Abstract:

A study was undertaken to determine the extent of genetic variability for seed yield and ten other quantitative characters and two qualitative characters in 45 genotypes of Niger. The analysis of variance revealed significant differences among genotypes for all the characters. High genotypic coefficient and phenotypic coefficient of variation was recorded for number of secondary branches per plant followed by number of capitula per plant, 1000 seed weight, seed yield per plant, number of seed per capitula and number of primary branches per plant, days to 50% flowering. The lower magnitude of GCV and PCV was observed in protein content, plant height, oil content, days to maturity and diameter of capitula. The high estimates of heritability in broad sense was observed for number of secondary branches per plant followed by number of capitula per plant, 1000 seed weight and number of seeds per capitula. Highest estimate of GA was noticed for number of secondary branches per plant. While, medium to low estimates of GA observed for number of capitula per plant, 1000 seed weight, seed yield per plant, number of seeds per capitula, number of primary branches per plant, days to 50% flowering, diameter of capitula, days to maturity, oil content, protein content, plant height. High heritability coupled with high genetic advance was recorded in number of capitula per plant, number of secondary branches per plant, 1000 seed weight, and number of seeds per capitula, which indicated the predominance of additive gene effects. Improvement in these characters could be exercised by simple selection due to fixable additive gene effects.
