Abstract

Rice panicle branching architecture is an important trait affecting yield, but its responses across different seasons have not been extensively studied yet. The aim of this study was to evaluate the panicle branching responses of fifteen rice genotypes on different seasons. This study was conducted from April 2017 to March 2018 at Babakan Experimental Station, IPB University, Dramaga, Bogor. Fifteen genotypes as treatments were grown in the dry and wet seasons to study the genotypes × seasons interaction effects on panicle branching. The experiment was laid out in a randomized complete block design with four replicates. Individual analysis and combined analyses over seasons were performed. The results revealed that the genotype, season, and genotype × seasons had significant effects on panicle length, number of primary branches, length of primary branches, and length of secondary branches. The results of the study may be useful for rice breeders in conducting selection based on panicle branching.

Keywords: dry and wet season, genotypes × seasons, rice breeding
