Abstract: Thirty genotypes of Little millet (Panicum sumatrance) at Junagadh, Gujarat during Kharif 2017 under Timely (E1), late (E2) and vey late (E3) sown conditions. The characters studied were days to 50 % flowering, days to maturity, number of productive tillers per plant, plant height, panicle length, grain weight per main panicle, grain yield per plant, biological yield per plant, harvest index, 1000 seed weight, chlorophyll content and specific leaf weight. In timely sown condition, the grain yield per plant had highly significant and positive correlations with plant height, number of productive tillers per plant, harvest index and specific leaf weight at both genotypic and phenotypic levels. In late sown condition, grain yield per plant had highly significant and positive correlation at both genotypic and phenotypic levels with number of productive tillers per plant and harvest index. In very late sowing condition plant height, number of productive tillers per plant and harvest index with grain yield per plant at both the levels. Overall in all sowing condition, number of productive tillers per plant and harvest index has significant and positive genotypic and phenotypic correlations. Path coefficient analysis revealed that harvest index, biological yield per plant, days to 50% flowering and specific leaf weight exhibited high and positive direct effects on grain yield per plant under timely sown condition. While in case of late sown condition, path coefficient analysis revealed that harvest index, biological yield per plant, chlorophyll content, plant height, grain weight per main panicle and panicle length exhibited high and positive direct effects on grain yield per plant. In very late sowing condition, character harvest index, biological yield per plant and days to 50 % flowering shows high and direct positive effect toward grain yield per plant. Among all sowing conditions, biological yield per plant, harvest index and specific leaf weight exhibited high and positive direct effect on grain yield per plant. The residual effect of the present study under timely, late and very late sowing condition was 0.264, 0.829 and 1-1.012, respectively indicating that characters suggested that there might be few more component traits responsible to influence towards grain yield per plant than those studied.
