The present study “Genetic variability analysis of yield and its components in Niger [(Guizotia abyssinica (L. f.) Cass.]” was carried out at the Instructional cum Research Farm of S.G. College of Agriculture and research station, Jagdalpur (C.G.) Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Kharif 2017. The experimental material comprised of 50 Niger germplasm and 3 check variety of Niger. The experimental materials were sown on September 2017 in RBD design with three replication with the objectives to estimate the genetic variability, heritability and genetic advance. Analysis of variance indicate that the mean sum of square due to genotypes were highly significant for all the characters. High genotypic coefficient of variation and phenotypic coefficient of variation were observed for capitulum per plant and seed yield per plant (g). The high heritability was recorded for the trait days to maturity and straw yield (g) followed by days to 50% flowering and oil content (%), plant height (cm), capitulum per plant, seed yield per plant (g) seed per capitulum, primary branches per plant and harvest index (%). Genetic advance a percentage of mean recorded high for capitulum per plant, seed yield per plant (g), seeds per capitulum, oil content (%), harvest index (%), primary branches per plant, plant height (cm) and straw yield (g).
