Abstract: An experiment was conducted in two replications with seventy germplasm lines during kharif 2012 at College of Agriculture, UAS, Raichur. The germplasm included 30 local varieties from different parts of Karnataka and 40 lines collected from AICRP, Jabalpur. Each entry was sown in three lines of 4 m length with 30 cm x 10 cm spacing. Out of seventy lines sixty two entries were germinated. These lines were evaluated for seed yield and other ancillary characteristics viz., days to 50% flowering, days to maturity, plant height, number of primary branches, number of capitula, number of seeds per capitulum and seed yield. Among them, six entries performed better than check variety No. 71 and 12 entries performed better than another check variety RCR 18. Among all the entries N-84 (238.89 kgha-1) and SD-33 (215.28 kgha-1) produced high yield. Hadagali local and No. 71 (51.5 days) were found earliest in flowering and maturing varieties and SP 141 was late in flowering (71 days) and late in maturing. Tavaregere local (66.5 cm) and SP134 had less plant height (67.5 cm) and BMD 127 had highest (113.5 cm) plant height. The number of primary branches was more in the genotype Humnabad local (12.5). Number of capsules plant-1 were more in Humnabad local and ICP 76 (53.0) and number of seeds capsule-1 were more in BMD 115 (77.0). Correlation studies revealed that plant height and number of seeds per capsule were positively correlated with seed yield. The 62 studied germplasm lines were clustered into two clusters.
