Abstract:

The present investigation entitled was carried out with 1700 germplasm lines along with 4 checks i.e. CSV17, CSV20, CSV27 and CSV21F provided by National Bureau of Plant Genetic Resources (NBPGR) through ICAR- Indian Institute of Millet Research (IIMR) Hyderabad. The experiment was laid out in augmented RBD with 60 replications during Kharif 2015 at Instructional Farm, Rajasthan College of Agriculture, Udaipur. The populations were employed for the assessment of genetic variability, heritability and genetic gain and observations were recorded for nine quantitative characters viz., days to 50 per cent flowering, plant height (cm), number of leaves, leaf length (cm), leaf width (cm), panicle length (cm), panicle width (cm), 100- seed weight (g) and grain yield per panicle ( g ) on five competitive plants selected at random for each germplasm lines except early vigour and days to 50 percent flowering which were recorded on whole plot basis. Availability of genotypes in different replication at the time of observations was not conform on account of germinations and shoot fly dead hearts therefore, data were analysed in augmented CRD. Analysis of variance revealed significant difference between genotypes for nine quantitative characters. Mean square due to germplasm was significant for all the characters. CSV17 was the best check for days to 50 percent flowering. CSV27 was the best check for leaf length, leaf width, panicle length and grain yield per panicle. CSV21F was the best check for panicle width, plant height and number of leaves.GCV, PCV and genetic gain were high for grain yield per panicle and heritability for 100-seed weight.
