GENETIC CORRELATION STUDIES IN SAFFLOWER (Carthamus tinctorius L.)

GAURAO MANOHARRAO KURHADE

Abstract


Present study was conducted to estimate the correlations among the different parameters which is directly correlated with seed yield and oil content in safflower with other traits. The recurrent selection experiments are mainly designed and conducted for improving seed yield plant'1. In the present study, days to 50 % flowering exhibited significant and negative correlation with number of capitula plant'1 (-0.26**), 100 seed weight (-0.21*) and seed yield plant1 (-0.25**) and also exhibited significant and positive correlation with plant height (0.30**). Plant height exhibited significant and positive correlation with days to maturity (0.22*) and oil content (0.26**). The number of primary branches plant'1 exhibited significant and positive correlation with number of capitula plant'1 (0.72**) and seed yield plant'1 (0.60**). Number of capitula plant1 exhibited significant and positive correlation with seed yield plant1 (0.78**). Number of seed capitulum1 showed that significant and negative correlation with 100 seed weight (-0.40**) and exhibited significant and positive correlation with seed yield plant'1 (0.23*). 100 seed weight exhibited significant and negative correlation with oil content (-0.28**). Days to maturity (-0.17) and oil content (0.14) showed non-significant correlation with seed yield plant'1.

In the present study, days to 50 % flowering and days to maturity exhibited negative correlation with seed yield plant'1 indicating breaking of positive correlation to negative correlation. This study on correlation and reports mentioned above will facilitates selection of recombinant lines with high yield and earliness.
