 ABSTRACT

The study envisaged assessing the stability analysis of the parents and hybrids, using line x tester mating design. Twenty four hybrids (derived from mating four testers with six lines in L x T design) along with their parents (10) and checks ((SSG 59-3 and MFSH 4)) were evaluated at two locations with two date of sowing (Early and late sowing) during the kharif season of 2015-16. Data on five randomly taken plants from each genotype in each replication were recorded on different quantitative characters at first cut and second cut. Stable hybrids are desirable for commercial exploitation over a wide range of agro-climatic conditions. When the mean sum of square due to environment (linear) was tested against pooled deviation, it was found significantly different for all the characters studied. This indicated that the environments were significantly different and warranted estimation of G × E interactions. Ten hybrids and three parents were found to have significant di2, indicating the presence of non-linear component for dry fodder yield. The higher green fodder yield was exhibited by hybrids 465A × G 46 and 467A × IS 2389 and were found stable and suitable for all the test environments while hybrid 31A × HJ 513 was found highly responsive for the favourable environments. The cross 31A × IS 2389 was found stable, average responsive and suitable for all the test environments for dry fodder yield while hybrids 14A × HJ 513 and 467A × IS 2389 were found highly responsive and suitable for the favourable environments. Hybrids 465A × HJ 513 and 9A × IS 2389 may be further advanced to select the good segregants for green and dry fodder yield as these had high sca and stability.
