ABSTRACT
Twelve niger genenotypes grown in a randomized block design with three replications in kharif 2014-15 and 2015-16 field experiment were conducted at JNKVV, ZARS, AICRP On Niger, Chhindwara, M.P. The highest magnitude of GCV was obtained for number of capitula/plant (15.73) followed by number of productive branches/plant (10.94), plant height (6.78) and seed yield/plot (6.13) and Low values of GCV was estimated for days to maturity (0.87) and days to 50 percent flowering (1.0) indicating the presence of lower genetic variability for these traits. Days to 50 percent flowering had significant positive correlated with days to maturity. Number of productive branches/plant had significantly positive correlated with number of capitula/plant, plant height days to maturity and seed yield/plot. Seed yield per plot positively correlated with number of productive branches/plant7 (Khuntey et al., 2015), number of capitula per plant, plant height and days to maturity at genotypic level and negatively was days to 50 percent flowering. So these traits like number of productive branches per plant, number of capitula per plant should be given priority during selection in yield improvement programme. Path analysis revealed that the significantly positive associations of number of productive branches per plant, number of capitula per plant, plant height and days to maturity for seed yield were due to high positive direct and indirect.
Key words: Correlation and Path, Genetic Parameters, Niger.
