摘要

The choice of an efficient breeding procedure depends to a large extent on knowledge of the genetic system controlling the character to be selected. To obtain information on the nature of gene action in West African okra, six generations of parents, first and second filial generations, back crosses 1 and 2 (P1, P2, F1, F2, BC1 and BC2) derived using Generation Mean Analysis (GMA) from crosses involving fourteen selected genotypes were evaluated. The experiments were conducted at the Teaching and Research farm of the University of Agriculture, Abeokuta (7 degrees 29N, 3 degrees 30E) during the growing seasons of 2008 and 2009. The data suggest that genes influencing some of the characters are dispersed among the parental lines and those interactions are predominantly of the duplicate kind. Additive gene effects were higher than dominance gene effects for most of the traits that were evaluated. Seed yield per plant for cross NGAE-96-0062-2 X CEN 015 was controlled by complementary gene action. Days to flowering, number of pods per plant, number of seeds per pod, matured plant height and seed weight per plant for the NGAE-96-0063 X CEN 015 cross was controlled by duplicate epistatic gene actions. The presence of significant amount of all types of gene action, additive, dominance and epistasis for most of the traits has indicated that methods designed to utilize all of them such as recurrent selection and reciprocal recurrent selection has to be adopted in the breeding programme.
