Abstract

  Diallel analysis of Hayman was performed removing reciprocal in basil, the experimental material consisted of morphological diverse genotypes and their 21 direct crosses i.e. F1 populations. The traits days-to-flowering (50%), plant height (cm), no of branches/plant, inflorescence length (cm), fresh herb yield (g)/plant, oil content (%), oil yield (g)/plant, days-to-maturity, methyl-chavicol content (%), linalool content (%), citral content (%), eugenol content (%) explored additive type of gene effects. t2 for all the characters are non-significance so its indicate validity of the hypothesis postulated by Hayman. Regression line for days-to-flowering (50%), days-to-maturity were below the origin showing the presence of over-dominance while for branches/plant, ocimene content, linalool content, camphor content and methyl-chavicol it was above the origin suggesting the presence of partial-dominance. Regression line for plant height, inflorescence length, fresh herb yield, oil content and oil yield were through the origin indicating the presence of complete-dominance. Narrow sense heritability estimates h^ 2(ns)% ranged from 7.9% (lowest) for inflorescence length to 59% (highest) for oil content. Genetic advance over mean ranged from 0.54 (days-to-maturity) to 53.11 (branches/plant).
