Abstract

Safflower (Carthamus tinctorius L.) is a multipurpose crop giving quality oil, but poorly studied for geneticsof traits. In the present investigation, 14 genotypes (germplasm lines and varieties) viz., JSF-1, RSS-2011-2, PKVPink, Aceitera, GMU-1303, PBNS-12, TGMS, RSS-2011-1-1, RVS-12-13, SAF-2036, GMU-1810, IIOR-SAF-39,NARI-6 and RSS-2016-7 were used as parents, which are diverse for many traits, to make 10 crosses. Theobservations of contrasting traits of parents, the trait appeared in F1 and F2 were recorded. The data recorded were analysed by c 2- test for goodness of fit. Some of the traits such as capitulum shape, days to flowering, leaf margin and capitulumsize appeared to be monogenic as the F2 population segregated in 3:1 ratio. Inheritance pattern ofleaf shape, petal colour, spines, bract shape and size and branching habit revealed complementary or inhibitory gene interactions, indicating involvement of two genes.
