Abstract
Fifteen jatropha lines were obtained from complex crossing between progenies derived from interspecific hybridization of Jatropha curcas and J . integerrima . They were evaluated for variability and association in yield, yield components, oil content, fatty acid composition, phorbol esters content, and growth characters . The major fatty acids in seed were oleic and linoleic acids, with a negative correlation among them. Seed yield showed a positive correlation with number of fruits per inflorescence and seeds per fruit, 100 seed weight and canopy size . A path coefficient analysis showed that number of fruits per inflorescence and canopy width had high positive direct relationship with seed yield per plant . Most characters showed high broad - sense heritability . Clustering by traits classified the breeding lines into five groups with a large distance between groups . The members in each group comprised lines of the same or similar pedigrees . Cluster I was the high seed yield group comprising two accessions (KUJL23 and KUJL18) . Clustering based on principle components classified them into four groups . The lines in cluster II and III from cluster analysis were included in one group, while members of the other groups were the same in both clustering methods .
