Abstract
Seventeen genotypes of radish were evaluated to determine their stability and adaptibity in six different environments during 2015-16 at PAU, Ludhiana. The data on growth, yield and quality characters and environmental variables were analyzed by AMMI model. The analysis revealed that the genotype RL-30 was stable for yield building factors in all the environments followed by genotype RB-21 (except in April). Genotype RL-2210 was stable for root plant ratio, root shoot ratio and quality characters. Among the environments, October was the best environment for testing the genotypes with wider adaptability followed by environment March. However environments April, December and August can be used to identify those genotypes that were specifically adapted to these environments. Genotypes Punjab Safed, LSR-2 and Pusa Jamuni 2 performed best in environment August. Selection-2, RB-21 and RL-2210 Long were found best in October. In December, Japanese White, RB-20 and RL-15 were good performer genotypes whereas in environment February Japanese White, RB-20 and RB-21 were better adapted. Selection-2, RL-2210 Long and RL-2210 performed best in March, while Punjab Safed and LSR-2 gave better adaptation in environment April. Total root yield had significant and positive correlation with marketable yield, root weight, plant weight, root diameter and root length. Path coefficient analysis revealed that marketable yield had the maximum positive direct effect on root yield followed by plant weight.
