Judul: Genetic analysis towards single crossed rose (rosa hybrida l.)
Abstrak: The information of genetic variability, heritability, genetic correlation among characters, path analysis, indices selection and genetic distance among parental are very important in rose breeding program. The use of selection indices based on measurement of several characters is more effective and useful in selecting superior rose genotypes which meet the established standard quality. The general aims of this study are to develop single crossed roses (Rosa hybrida L.) hybrids and choose good parent candidates to create double cross hybrids based on genetic distances. The specific aims of this study are to get information about variability, heritability, correlation among the characters being observed, path analysis and to use selection indices based on quality characters of rose for obtaining qualified cultivars and to estimate genetic distances based on phenotypic performances. The genotypes were arranged in a randomized complete block design with three replications and sub-sampling. Observations were made on fourteen quantitative characters and fifteen qualitative characters related to quality were being analyzed by using cluster analysis of Ntsys 2.02 software. The results of the study showed that the characters length of stalk, number of leaves, number of nodes, number of petals, number of large thorn, and days to harvesting were large genetic variability and high broad sense heritability. A real positive correlation occurred between length of stalk with number of leaves, number of nodes, neck length, number of large thorn and number of flower per plant, while days to harvesting have negative correlation. Flower bud diameter had a real positive correlation with vase life and number of petals, while the real negative correlation with bloomed flower diameter. Vase life had a real correlation with flower bud diameter, stalk diameter, number of leaves , number of nodes and number of flower per plant, while the real negative correlation with neck length. Bloomed flower diameter had a real positive correlation with flower bud diameter, number of petal and number of petals, while the real negative correlation with number of small thorn. Number of flower per plant had a real correlation with length of stalk, bloomed flower diameter, length of nodes, neck length and vase life, while the real negative correlation with days to harvesting. Number of nodes and number of flower per plant had positive direct effects on length of stalk, while neck length and number of leaves had negative direct effect. Number of petals has positive direct effect to flower bud diameter. Flower bud diameter, stalk diameter and number of leaves had positive direct effects on vase life, while number of nodes has negative direct effect. Flower bud diameter, number of petals and number of flower per plant had positive direct effects on bloomed flower diameter. Length of stalk, bloomed flower diameter, length of nodes and neck length had positive direct effects on number of flower per plant. Based on the brightness of flower colors, genotypes 97.100-36, 95.077-01, 97.100-31, 97.105-80 and 97.167-01 were selected. Indices selection based on economic value selected genotypes 97.105-80, 97.174-01, 97.029-82, 95.077-01 vi and 97.106-42. Based on heritability, selected genotypes 97.105-80, 97.174-01, 97.029-82, 95.077-01 and 95.090-04, while based on direct effect

Judul: Quantitative Traits Inheritance of Crossed Big and Curly Chili.
Abstrak: Chili is divided into types based on the fruit size, such as cayenne, big chili, curly chili and paprika. Varied behavior of Indonesian people in chili cultivating and consuming based on size causes low national chili productivity. First step in plant breeding was base population formation with high genetic variance. The genetic variance could be obtained by exploration, introduction, hybridization and mutation. Information of traits genetic inheritance was studied by hybridization. The research used 20 genotypes cultivated and characterized in two locations, i.e. Rimbo Panjang and Leuwikopo. Different places of cultivation were expected to separate the genetic-by-environment interaction effects from their genetic effects. Genotypes grouping based on the similarity using cluster analysis. High genetic coefficient and broad sense heritability were observed for several traits and proceed to get the selection criteria. Selection criterias used were yield per fruit, length of fruit, number fruit per plant and plant height. Then, genetic parameters, combining ability, heterosis and hybrid performance were observed from full diallel population (6×6). Genetic parameters were estimated by Hayman method while combining ability by Griffin method. Dunnett test was used to show hybrid performance. Genetic variance affected with several traits was additive and non-additive. Gene distribution did not spread evenly in parents, except leaves width, plant height, stem diameter and fruit stalk length. Partial dominance level affected each several traits performance. Number of controlling gene groups of traits were ranged between one to four groups. High broad sense and narrow sense heritability were suggested for several characters. General combing ability (GCA) and specific combining ability (SCA) influenced significantly in some observed traits, except leaves width, stem diameter and fruit stalk length. Genotype C5 was selected parent with best GCA in some observed traits and recommended to be developed subsequently as open-pollinated variety. Those were hybrids that were potential to be further tested, i.e. C2×C19, C5×C2, C5×C19, C19×C2, C19×C5, C2×C120, C5×C111, C5×C120, C19×C111, C19×C120, C111×C5, C120×C5, C159×C5, C2×C159, C120×C19, C111×C120, C159×C120, C111×C159, C120×C159 and C159×C111.
