ABSTRACT
Correlation and path analysis studies in 50 little millet genotypes revealed strong, significant and positive association of harvest index, number of productive tillers plant-1, plant height, panicle length and thousand seed weight with grain yield plot-1 at both phenotypic and genotypic levels indicating yield improvement could be possible through the indirect selection for these traits. Harvest index, number of productive tillers plant-1, leaf area index at panicle initiation, leaf area index at 15 days after panicle initiation, relative injury at 15 days after panicle initiation, main panicle weight, panicle length, SCMR at panicle initiation and thousand seed weight showed maximum positive direct effect on grain yield plot-1 indicating the true relationship between these traits with grain yield. Hence, direct selection for these traits would be rewarding for improvement of grain yield in little millet.
Key words :
Correlation, Little millet, Path analysis, Yield attributes.
