About the creation of sterile lines of sweet pepper in breeding for heterosis
Authors: Koroleva S. V. , Polyakova N. V. , Pistun O. G. 
Published: October 2020

Relevance. Development of valuable sterile lines of sweet pepper using nuclear-cytoplasmic male sterility is associated with the search for stable sterility maintainers in collection material.Material and methods. The purpose of the research is to optimize the identification of the desired genotypes and accelerate the development of sterile lines using artificial climate chambers. The research material was a sterile line msTol55, which under the conditions of a film greenhouse showed partial fertility at the beginning or at the end of the growing season. The place of cultivation is artificial climate chamber, a film spring greenhouse.50-day-old seedlings were planted in pots on 10.01, the period of growing plants in the chamber - until 20.04, then the adult plants were transplanted into a spring film greenhouse. According to the traditional technology, the cassette seedlings of the same line were planted in the greenhouse on 15.04. The number of tested plants is 16-20 pcs. Growing mode in the chamber: 12 hours were illuminated with DRLV lamps, while the temperature was at the level of 26-28°C, from 20.00 to 8.00 the lamps were not illuminated, the temperature was 14-15°C. The actual sterility / fertility of the flowers was determined by the level of contamination of the fruits at the beginning of their formation.Results. The maintained temperature regime for growing in an artificial climate chamber made it possible to identify sterile (30%) and partially fertile plants (70%) in the first 2 weeks of flowering. When adult plants were transplanted into a spring greenhouse, the number of sterile plants increased to 56%. When growing the line msTol55 in a spring greenhouse using the usual technology, partial setting of seeded and little seeded fruits on 60% of the plants was observed from the third decade of May to the second decade of July, then all plants set only non-seeded fruits. Based on the results obtained, it is advisable to identify the breeding material for the Rf gene in the ACC, since the proposed growing regime serves as a provocative background and allows for more effective control over the manifestation of sterility.
The breeding method and its influence on the intensification of the tomato selection process
Authors: Маkоvеi M. D. 
Published: October 2020

Relevance. The article presents the results of using three different selection methods to obtain new forms of tomato that combine high productivity with resistance to high-temperature stress factor.Methods. Eleven hybrid combinations were used as experimental material. Selections were made starting with the offspring of the F1 generation. Three different methodological approaches were used: 1 – step-by-step alternation of sporophytic-gametophytic selections under high temperature pressure; 2 – only gametophytic selection using heat-treated pollen for pollination; 3 – traditional selections based on a high value of indicators of the studied traits. In each of the variants of the experiment, we studied: the heat resistance of offspring at different stages of ontogenesis – "sporophyte-gametophyte"; the duration of the vegetation period of plants; the fruit formation; the total yield. The offspring of the most stable and productive plants isolated from different hybrid combinations were combined in the populations in each variant of the experiment and a comparative analysis and evaluation of the effectiveness of the methods used was carried out.Results. It is shown that the combination of step-by-step sporophyte-gametophyte selections under the action of high-temperature regimes (43°C and 45°C), at early stages (F1–F3) lead to more stable, productive offspring in F5-F7 both for sporophyte and gametophyte traits, compared to using only gametophyte selections and stronger differences relative to the control variant. The gradual alternation of selections at different stages of ontogenesis also leads to the production of offspring with a shorter period of passage of the phenophases "seedling-flowering" – "floweringmaturation" and a stable manifestation of signs that determine the quality of the fruits. Using only gametophytic selections and traditional methods of selection was less effective than alternating sporophyte-gametophyte ones.Conclusions. The differentiating ability of the selection methods used and their influence on obtaining more resistance and productive genotypes was established. The advantage of the method of step-by-step alternation of sporophyte-gametophyte selections, which led to the production of new lines (118/1, 124/1, 133-11/1, 133-12/1, 134/1, 110/1 and 7/1) with high resistance at different stages of ontogenesis (sporophyte-gametophyte), shorter vegetation period and high fruit-forming capacity in three different years of research (2015-2017).

Relevance. Due to the wide diversity of cultivars and rootstocks, the selection of more productive, commercial and adapted graft-rootstock combinations for industrial orchards in the Orel region and the entire Central Chernozem region is relevant.Materials and methods. The studies were carried out at the Russian Research Institute of Fruit Crop Breeding (VNIISPK) on the bases of the laboratory of cultivar study and cultivar agrotechnics of pome crops and the laboratory of physiology of fruit plant resistance. Winter apple cultivars of VNIISPK breeding ‘Sinap Orlovsky’, ‘Veteran’, ‘Orlik’, ‘Rozhdestvenskoye’, ‘Svezhest’, ‘Bolotovskoye’, ‘Veniaminovskoye’ and control cultivar ‘Antonovka Obyknovennaya’ on the vegetatively propagated semi-dwarf rootstock 54-118 were taken as objects of the studies. The orchard was planted in autumn 2013, the planting scheme was 6 mx3m.Results. The studied apple cultivars have good compatibility with 54-118 rootstock, provide good tree development and low-sized crown. The highest yield on average for three years was in scab-immune apple cultivars ‘Bolotovskoye’ (4.6 t/ha), ‘Rozhdestvenskoye’ (3.4 t/ha) and ‘Venyaminovskoye’ (3.2 t/ha). The highest indicators for the load of the crop on the crown volume, crown projection area, and cross-sectional area of the stem were for ‘Svezhest’ and ‘Bolotovskoye’. As a result of determining the frost resistance of apple cultivars in mid-January to temperatures up to -38...-40°C, it was revealed that in the hardened state, the cultivars showed frost resistance of buds and tissues of annual shoots with reversible damage at -38°C in the middle of winter. A decrease in temperature to -40°C in January increased damage to buds and wood in the studied varieties, while the bark was characterized by greater frost resistance. According to the degree of damage to the cortex in January, when the temperature dropped to -40°C, ‘Rozhdestvenskoye’, ‘Svezhest’, and ‘Sinap Orlovsky’ were at the control level.

Authors: Semin I. V. , Dolmatov E. A. , Ozherelieva Z. E. 
Published: October 2020

Relevance. Unfortunately, there are no intensive pear plantations in the central regions of Russia due to the absence of intensive dwarf rootstocks. Therefore, the research aimed at obtaining winter-hardy rootstocks that provides early industrial fruiting of gardens, limits plant growth and gives a quick return on investment, is very important and can be applied in many different ways.Materials and methods. The research was carried out in the laboratory of selection and variety study of pears and non-traditional pome crops of the Russian Research Institute of Fruit Crop Breeding (FSBSI VNIISPK). The object of the research was the common quince selected by FSBSI VNIISPK. In 2008-2010 and 2012-2014 we studied the economic and biological characteristics of the common quince as clonal pear rootstocks when propagated by green cuttings.Results. The research results show high winter hardiness of the common quince plants in Oryol region, as well as their high regenerative capacity in case of damage caused by adverse winter conditions. It was determined that some types of common quince can be reproduced by green cuttings and provide a high yield of uniform planting material. The common quince has a high seed productivity that allows to get seedling rootstocks of high quality. Some pear cultivars demonstrate a good compatibility with the common quince, moderate growth and high early maturity in comparison with the pear rootstock; there are also preliminary data on compatibility of 11 pear cultivars in a nursery, and 4 cultivars that are incompatible with the common quince.

Published: October 2020

Em 2008, o Brasil adotou a política de erradicação do sub-registro civil de nascimento e de promoção do acesso à documentação básica. Passados 10 anos de atividades, diz-se que o país erradicou o sub-registro civil de nascimento, embora os dados mostrem que cerca de 1% das crianças nascidas no país permanecem sem registro. Considerando que o registro civil de nascimento é um direito humano que garante o exercício dos demais direitos e, sabendo que os esforços brasileiros para erradicação do sub-registro têm sido considerados exitosos, este artigo analisa os 10 anos da política nacional sob a perspectiva das políticas públicas em direitos humanos, identificando, ainda, os impactos da descentralização da política nos órgãos públicos no alcance das metas estabelecidas no decênio 2008-2018. Conclui que as ações coletivas, a padronização documental e dos sistemas de informação contribuíram para o sucesso dessa política pública; no entanto, permanecem os desafios de registro civil de nascimento dos chamados grupos prioritários. A metodologia de pesquisa consiste em revisão bibliográfica e análise de dados estatísticos oficiais do governo brasileiro.Palavras-chave: Registro civil de nascimento. Brasil.

Utility of the optical quality analysis system for decision-making in Nd: YAG laser posterior capsulotomy in patients with light posterior capsule opacity
Authors: Lu Bo , Zhu Weijie , Fan Yu , Shi Dong , Ma Liwei 
Published: October 2020

Abstract
Background: A prospective cohort study was performed to evaluate whether the Optical Quality Analysis System (OQAS) can serve as a valuable additional indicator for appropriate posterior capsulotomy referral. Methods: One hundred and five eyes from 96 patients undergoing capsulotomy were divided into precapsulotomy logMAR CDVA ≤ 0.1 group and logMAR CDVA > 0.1 group. CDVA， and the Visual Function 14 index (VF-14) score were estimated before and one month after capsulotomy. The objective scattering index (OSI) value was measured by using the OQAS. Posterior capsule opacification (PCO) severity was assessed with Evaluation of PCO 2000 (EPCO 2000) software. Results：In logMAR CDVA > 0.1 group, the correlations of OSI, logMAR CDVA, EPCO score and VF-14 score were very strong preoperatively. In logMAR CDVA ≤ 0.1 group, preoperatively, OSI was correlated with logMAR CDVA (r = 0.451), EPCO score (r = 0.789), and VF-14 score (r = 0.852). LogMAR CDVA has weak correlation with VF-14 score (r = -0.384) and EPCO score (r = 0.566). VF-14 score was correlated with EPCO score (r = -0.669). In the logMAR CDVA ≤ 0.1 group, there was no significant difference in logMAR CDVA between precapsulotomy and postcapsulotomy (P > 0.05). In the two groups, all the other optical quality parameters were significantly improved after capsulotomy (P < 0.05). In logMAR CDVA > 0.1 group, the area under the curve of the ROC of the OSI was 0.996 (P = 0.000). In logMAR CDVA ≤ 0.1 group, the area under the curve of the ROC of the OSI was 0.943 (P = 0.000).Conclusions：The OSI was useful for evaluating of PCO and prediction of beneficial capsulotomy. Especially for patients with slight PCO and better visual acuity, OSI is more valuable than CDVA and completely objective examination. Trial registration: The study protocol was registered at the Chinese Clinical Trial Registry. Register: ChiCTR1800018842 (Registered Date: October 13th, 2018).
