Estimates of genetic components and heritability from a diallel cross in Egyptian cotton [electronic resource].

Includes reference.

A half diallel crosses involving five Egyptian colton genotypes was used to study the inheritance of seed-cotton yield per plant and lint yield. The analysis of the Fl generations and parents revealed that both additive and dominance gene effects were Important in controlling the variation in the yield traits, but the effects of genes acting additively were more pronounced. The 0 parameter denoring additive variance was larger than the dominance H,. Partial dominance was manifested for all studied traits. Narrow sense heritability was high for flowering time (O.81), seed-colton yield (0.87) and lint yield (O.83) but low for lint percentage (0.18).
