The present study was undertaken; to evaluate the response of recurrent selection derived lines by the testing of (C3) derived lines for genetic variability, genetic advance and heritability and to assess the effect of selection on other quantitative traits. The 16 half-sib families were selected from 3rd cycle of recurrent selection were grown for evaluation in Randomized Block Design in Rabi 2009 -10 along with check varieties Bhima and A1. The expected genetic advance expressed as per cent of population mean at 10 per cent was high for seed yield per plot (48.84) followed by seed yield per plant (28.88). The expected genetic advance per cent over Bhima at 10 per cent selection intensity was high for seed yield per plot (28.27) followed by seed yield per plant (22.78). In safflower seed yield per plant was positively and significantly correlated with days to maturity, number of capitula per plant, number of seeds per capitulum and 100 seed weight. Days to maturity and seed yield per plant had exhibited significant and positive correlation. Two halfsib families were identified for testing in preliminary yield evaluation trial.Keywords

Selected lines of safflower (Carthamus tinctorius L) were used to predict the heterosis for yield and yield components and to assess the reliability of prediction methods. The highest magnitude of useful heterosis was observed in respect of number of seeds per capitula (53.78%), seed yield per plant (27.23%), 100 seed weight (2.58%) and days to maturity (-2.87%). Only one cross, AKMS 1 x JLSF 228 recorded significant useful heterosis over the check variety Bhima for seed yield per plant (27.23%).The parents JLSF 228, A1 and Bhima were good general combiners for seed yield per plant. The predictive model was effective for describing hybrid. There was, however, the positive relationship between mid parent and hybrid yield indicating that mid parent may still be a useful guide for the selection of parents for testing hybrid combinations. The effectiveness of predictive and postdiction model differed for different characters except for number of seeds per capitulum and days to maturity for which both models were equally effective in predicting hybrid yield.Keywords
