Abstract

Phenotypic co-efficient of variation, genotypic coefficient of variation, heritability, genetic advance and genetic correlation for nine characters were estimated in thirty three geriotypes of rainfed niger. Considering the estimates of variability and correlation, it was observed that selection for number of branches and capitula per plant is likely to increase the yield of Niger plant. But the genetic variability and genetic advance for these characters are low. Thus more genetic variability for these characters are to be created and selection should be based on these characters to improve yield. Therefore, the first cycle of selection should be based on number of seeds per capitula and there after more genetic variability for number of branches and capitula per plant needs to be created for second cycle of selection.
