An experiment was conducted to evaluate 32 rice hybrids for yield and quantitative characters during Kharif-2015. The data were recorded on 13 quantitative characters to study genetic variability, heritability, and genetic advance. Analysis of variance among 32rice hybrids showed highly significant differences for all the characters indicated the presence of substantial amount of genetic variability for all the characters. Based on mean performance high grain yield per hill was observed for hybrid IHRT-E-22 followed by IHRT-E-23. High phenotypic and genotypic coefficient of variation (PCV) was observed for Flag leaf length followed by biological yield indicating that environment highly influenced these characters. High estimate of heritability was observed for test weight and plant height.
