Abstract:

The present investigation was carried out during kharif 2016 at the Agricultural and Horticultural Research Station, Kathalagere and other five locations under University of Agricultural and Horticultural Sciences, Shivamogga, Karnataka, to know the stability of the Twenty three advanced genotypes including three checks of paddy. Highly significant differences among genotypes were observed for all the characters except number of number of tillers, panicles fertility percent. The variance due to Genotype x Environment found significant for the characters like days to maturity, Plant height, Panicle length (cm) and number of spikelets per plant. Environment (linear) interaction component was significant for all the traits. The variance due to pooled deviation (non- linear) was highly significant for all the characters except for harvest index which reflect considerable genetic diversity in the material. Out of 23 genotypes studied six entries viz., JT-2-16-1, JT-2-22-5, JA-4-3, JT-2-15-1, JB-1-20-2 and JK-1-7-5 were consistent and high yielding compared to local checks, from the present study genotype JA-6-2 was found to be a stable across the environments.
