Panicle branching of nutritious rice based on good agricultural practices

Abstract

Panicle branching is one of the characters that can distinguish one rice cultivar from another. Agricultural practices determined the performance of panicle branching. The trial aimed to study the differences among ten rice lines based on panicle branching characters cultivated based on good farming practices. Seven pure lines and three varieties were planted as genetic material in 4 replications. The trial was conducted in Bandung in 2020 at an altitude was 460 m asl. The characters observed were panicle length, main axis length, number of total grain per panicle, number of primary branches, number of secondary branches, primary branch length, secondary branch length, and number of secondary branches primary branch. All the panicle branching characters showed different among genetical material planted. The longest panicle was found in IR 105730-B-79-1-4-SKI-1-8, but the longest main axis length was found in Inpari IR Nutrizinc, local variety and IR 105730-B-79-1-4-SKI-1-8. The genotype of IR 105734-B-64-1-1-SKI-1-SG-11 showed had the most grains number (223.28), and the genotype of IR 105730-B-79-1-4-SKI-1-8 was not different with IR 105734-B-64-1-1-SKI-1-SG-11. In the other characters, the genotype of IR 105730-B-79-1-4-SKI-1-8 was relatively showed a good performance, especially in primary branch length, secondary branch length, and number of secondary branches primary branch.
