STUDIES ON GENETIC VARIABILITY AND INTER-RELATIONSHIP BETWEEN GRAIN YIELD AND ITS COMPONENTS IN FOXTAIL MILLET (SETARIA ITALICA)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 5
Abstract
An investigation was carried out to assess the genetic parameters like variability, heritability and genetic advance, character association and path analysis for five yield component characters viz., plant height, number of productive tillers per plant, days to 50% flowering, days to maturity and grain yield per plot in 23 genotypes of Foxtail millet (Setaria italica). The genotypic coefficients of variation for all the characters studied were lesser than the phenotypic coefficients of variation indicating the interaction of genotypes with environment. High heritability coupled with high genetic advance was observed for grain yield per plot indicating the importance of additive gene action in governing the inheritance of these traits. Hence, simple selection is effective to improve the respected trait. Association studies revealed that, four out of five characters exhibited highly significant positive correlation with grain yield per plot both at phenotypic and genotypic levels. However, the traits plant height, number of productive tillers per plant, days to 50% flowering and days to maturity were found to possess significant association in desirable direction with grain yield per plot at both genotypic and phenotypic levels. Path analysis studies revealed that plant height, number of productive tillers per plant showed true relationship by establishing significant positive association and direct effect on grain yield per plant both at genotypic and phenotypic levels and days to maturity at phenotypic level.
