Genetic variability studies in azwain (<em>Trachyspermum ammi</em> L.)
Narendra Pratap Singh, VP Pandey and AK Singh
Thirty genotypes of azwain were evaluated for their genetic variability, heritability and potential for screening suitable genotypes for future improvement programmes. Analysis of variance showed the mean sum of square due to treatment was highly significant difference for all the ten characters, indicated presence of sufficient variability in the studied materials. Genotypes, NDAZ-22, NDAZ-20, NDAZ-25, NDAZ-5 and NDAZ-27 were identified as most promising genotypes for seed yield per plant. Highest genotypic and phenotypic coefficient of variation was exhibited by test weight followed by number of umbellets per umbel, weight of grains per umbel and number of primary branches per plant. High estimates of heritability in broad sense was observed for the characters like test weight g (93.19 %), number of umbellets per umbel (91.92 %), weight of grains per umbel (89.64 %), days to maturity (88.34 %) and number of branches per plant (85.99 %). The genetic advance as per cent of mean was highest in case of test weight g (37.45 %) followed by number of umbellets per umbel (29.78 %), weight of grains per umbel g (25.21 %), number of branches per plant (23.93 %), yield/plant (10.83 %), and days to maturity (10.78 %), indicated these characters had additive gene effect and therefore, these are more reliable for effective selection.
