ABSTRACT
Correlation and path analysis were studied in 78 genotypes for 10 characters during rainy season and summer season in 2013 and 2014. The study indicated that direct selection based on the traits, days to maturity, plant height, number of tillers, panicle length, panicle weight, test weight and straw weight during rainy season where as in post-rainy season days to maturity , panicle length, panicle breadth, panicle weight and straw weight are effective as the association and direct effects were positive for these traits with grain yield. The path analysis study indicated that direct selection based on the characters, panicle weight, test weight and straw weight showed high and positive effect on grain yield per plant in both rainy and summer season indicating the true relationship between these characters with grain yield per plant, which helps in direct selection for these traits thus in improving the grain yield per plant.
Key words :
Correlation, Foxtail millet genotypes, Grain yield, Path analysis, Setaria italica.
