Judul: Analisis akumulasi panas pada perkembangan tanaman cabai Bolivian Rainbow (Capsicum annuum)
Abstrak: Bolivian Rainbow (BR) chilli has four fruit colours that changes according to its level of maturity development. This characteristic makes BR chilli suitable as ornamental pepper rather than consumed. This research aimed to analyze and calculate the heat unit in the development of BR chilli inside and outside the greenhouse. The development of BR chilli is divided into vegetative and generative phases. The average temperature in the greenhouse was 28.0 °C with a maximum temperature of 37.0 ºC. The average temperature outside the greenhouse was 26.3 °C with a maximum temperature of 41.0 ºC. The growing response of BR chilli outside greenhouse in this study was better than its response inside greenhouse. Too high greenhouse temperature was not suitable for the development of BR. Development stage of BR inside greenhouse stopped at FG6 phase with heat unit of 907 ºC. Development stage of BR outside greenhouse could reach until FG14 phase with heat unit of 1470 ºC. The concept of heat unit could not be used to explain the linear correlation between temperature and plant development if the temperatures were not within the optimum temperatures for the plant.

Judul: Morphological and Productivity Analysis of the Second Generation of Curly Chili Mutants (Capsicum annuum L.) Resulting from Gamma-Ray Irradiation
Abstrak: Cabai (Capsicum annuum L.) merupakan komoditas hortikultura yang banyak dibudidayakan untuk keperluan industri makanan maupun kesehatan. Salah satu faktor yang mempengaruhi produktivitas cabai adalah kondisi iklim. Pemuliaan tanaman cabai dilakukan guna mendapatkan varietas yang tahan terhadap cekaman lingkungan untuk memenuhi kebutuhan cabai di masyarakat. Salah satu upaya untuk merakit varietas cabai unggul dapat melalui iradiasi sinar gama. Penelitian dilakukan bulan Oktober 2023-April 2024 di kebun Percobaan PKHT IPB Pasir Kuda. Penelitian menggunakan rancangan kelompok lengkap teracak (RKLT) 3 ulangan dengan faktor tunggal yaitu genotipe. Hasil penelitian menunjukkan bahwa produktivitas genotipe uji HTCkr-1, HTCkr-11, dan HTCkr 2 memiliki potensi produktivitas yang tinggi meskipun tidak memiliki perbedaan signifikan terhadap varietas pembanding. Hasil produksi belum mencapai produktivitas nasional akibat faktor cekaman lingkungan yang cukup ekstrem. Pengamatan karakter kualitatif tidak menunjukkan variasi fenotipe pada seluruh genotipe uji. Analisis korelasi menunjukkan produktivitas cabai keriting memiliki hubungan positif yang sangat nyata terhadap karakter umur berbunga, umur panen, tinggi tanaman, tinggi dikotomus, diameter batang, lebar tajuk, diameter buah, bobot per buah, jumlah biji per buah, jumlah buah per tanaman, bobot buah per tanaman, dan bobot buah per petak., Chili pepper (Capsicum annuum L.) is a horticultural commodity widely cultivated for the food and health industries. One factor affecting chili productivity is climate conditions. Chili plant breeding is conducted to develop varieties that are resistant to environmental stress to meet the community's chili needs. One approach to developing superior chili varieties is through gamma-ray irradiation. The research was carried out from October 2023 to April 2024 at the PKHT IPB Pasir Kuda Experimental Field. The study used a randomized complete block design (RCBD) with three replications and a single factor, namely genotype. The results showed that the productivity of the tested genotypes HTCkr-1, HTCkr-11, and HTCkr-2 had high productivity potential, although there were no significant differences compared to the control variety. The production results of this research had not reached national productivity levels due to the quite extreme environmental stress factors. Observations of qualitative characteristics did not show phenotypic variation in all tested genotypes. Correlation analysis showed that the productivity of curly chili had a highly significant positive relationship with the traits of flowering age, harvest age, plant height, dichotomous height, stem diameter, canopy width, fruit diameter, fruit weight per fruit, number of seeds per fruit, number of fruits per plant, fruit weight per plant, and fruit weight per plot.
