Stability assessment in late duration rice hybrids 21 STABILITY ASSESSMENT IN LATE DURATION RICE HYBRIDS

Analysis of variance carried out for eight quantitative traits on twenty-five genotypes (twenty-one hybrids and four check varieties) revealed significant genotypic differences at all the five locations for al the traits. Genotypes x location interactions were found to be significant for all the characters except 1000-grain weight. The variance due to genotype x location (linear) was significant only for days to 50 % flowering. Non-linear component was found to be significant for all the characters. Among the 25 genotypes studied, only six rice hybrids had given significantly superior yield tha
