Judul: Performance of Agronomic Characters in the Sorghum (Sorghum bicolor (L.) Moench) F3 Population Resulting from the Soraya 3 x Kawali
Abstrak: THEODORUS LEONARDO PAGAWAK. Performance of Agronomic Characters in the Sorghum (Sorghum bicolor (L.) Moench) F3 Population Resulting from the Soraya 3 x Kawali Crossbreeding Supervised by DESTA WIRNAS. Sorghum is one of the cereal crops that produces carbohydrates and can be used as a substitute for staple food other than rice. The development of sorghum varieties is very important to increase productivity and yield. This study aims to compare the selection results based on the diversity of agronomic characters in the F3 sorghum population and its two parent varieties, Soraya 3 x Kawali. The research was conducted in West Bogor. The materials used were F3 sorghum seeds resulting from the Soraya 3 x Kawali crossbreeding and seeds of the two parent varieties. Based on the analysis of variance and heritability conducted on several tested characters, each population showed diverse results. Specifically, the analysis of the genetic coefficient of variation for each character showed results ranging from medium to high, indicating the potential for improvement through selection. Based on the selection differential values, the panicle diameter and panicle weight were 0.32 and 1.36, respectively. Keywords: Rice, character, growth, crossbreeding, Soraya, Sorghum.

Judul: Diversity of Agronomical Characters and  Grain Type of Sorghum F2 Population Pulut 3 x Soraya 3
Abstrak: Pemanfaatan sorgum belum banyak dikembangkan di Indonesia karena kurang diminati oleh masyarakat. karena memiliki tekstur yang keras. Selain itu, terbatasnya varietas berdaya hasil tinggi menyebabkan produktivitas sorgum yang rendah. Penelitian ini bertujuan mendapatkan informasi keragaman karakter agronomi dan tipe biji sorgum, serta mendapatkan genotipe berdaya hasil tinggi dengan tipe biji waxy dari hasil persilangan Pulut 3 x Soraya 3 populasi F2. Penelitian ini dilaksanakan di Kebun Percobaan Muara, IP2TP Muara, Bogor pada bulan Agustus 2023 – Januari 2024. Hasil penelitian menunjukkan terdapat keragaman pada semua karakter agronomi yang diamati. Sebagian karakter yang diamati dikendalikan oleh aksi gen epistasis atau aditif tanpa epistasis dengan jumlah gen yang mengendalikan sedikit dan banyak. Terdapat keragaman karakter tipe biji sorgum yaitu tipe biji waxy dan non-waxy. Diferensial seleksi pada 30 genotipe waxy berdasarkan karakter diameter malai meningkatkan 31,3% bobot biji per malai., Utilization of sorghum has not been extensively developed in Indonesia due to its lack of public interest, primarily because of its hard texture. Additionally, the limited availability of high-yielding varieties has resulted in low sorghum productivity. This study aims to obtain information on the agronomic character diversity and grain type of sorghum, as well as to obtain high-yielding genotypes with waxy grain types from the crossbreeding of Pulut 3 x Soraya 3 F2 populations. The study was conducted at the Muara Experimental Garden, IP2TP Muara, Bogor, from August 2023 to January 2024. The research results showed that there is diversity in all observed agronomic characters. Most of observed characters are controlled by epistatic or additive actions without epistasis, with a small and large number of genes controlling them. There is diversity in sorghum grain types, including waxy and non-waxy types. Differential selection on 30 waxy genotypes based on inflorescence diameter increased the weight of grain per inflorescence by 31.3%.
