Abstract

Sixteen genotypes of Jatropha curcas collected from four states of India were evaluated in a replicated trial to find genetic variability for stay green (SG) trait and the association between stay green trait and yield component traits. Stay green was evaluated by visual observation. Phenotypic and genotypic coefficient of variation along with heritability was high (>90%) for SG trait correlation study showed that say green trait had significant positive association with seed yield/plant (r=0.88), fruits/plant (r=0.81), fruits/bunch (r=0.71) and seeds/fruit (r=0.60), but its association with 100 seed weight was positive and non-significant. This investigation revealed that substantial variation exists for SG trait and this trait could be used as an effective selection criterion for yield improvement in Jatropha curcas.
