Title

INVESTIGATION OF VARIATION AND DETERMINATION OF GENETIC DISTANCE AMONG 25 GENOTYPES OF SPRING SAFFLOWER (CARTHAMUS TINCTORIUS L.)

Pages

  44-53

Abstract

SAFFLOWER (Carthamus tinctorius L.) is one of the plants which has a high adaptation to different conditions such as resistance to drought and it is suited to be grown in arid and semi-arid regions. In this experiment, 25 genotypes of spring SAFFLOWER including Iranian local genotyps and foreign cultivars were evaluated in a simple lattice Design (5x5) in 2004-2005 in Karaj. Different traits studied include: head number each plant, seeds each head, plant height, number of secondary branches, days to flowering, days to maturity, oil percentage, 1000 seed weight, seed and oil yields. The results showed that there were significant differences among the genotypes for all traits. The highest seed and oil yields belonged to I.L.111 and T.N.612-A.Seed yield had positive and significant relationships with head number each plant, number of secondary branches, days to flowering, biomass and oil yields. Cluster analysis using Ward's method and Euclidian distances, classified the 25 genotype into three clusters.
