SIMPLIFIED TRIPLE TEST CROSS ANALYSIS IN SAFFLOWER (CARTHAMUS TINCTORIUS L.)

Published on

The study revealed importance of epistasis in the inheritance of yield contributing
traits and possibility of its detection in Safflower. Epistasis was present for all the
characters except number of main branches per plant and oil content. In presence
of epistasis the estimates of genetic coml>onents would be biased. The present
analysis is applicable to those four characters for which the testers had extreme
phenotypes. Thus precise estimates of additive and dominance components were
obtained for only number of main branches per plant. In presence of preponderance
of additivity, the methods like simple selection has been advocated for further
improvement in safflower.
