Abstract
The feasibility of identifying superior parents of peanuts (Arachis hypogaea L.) by testing Fl hybrids grown under controlled conditions was investigated. Estimates of combining ability, maternal, and reciprocal effects among 15 F1 hybrids were determined for 17 seedling characters. Six lines of cultivated peanuts were crossed in all possible combinations to form a 6 × 6 complete diallel set. The lines included Valencia, Virginia, and Spanish types from three geographic regions of South America. Statistically significant variances were found for general combining ability for 11 of the 17 characters. Estimates of specific combining ability for three characters were statistically significant. The greatest portion of genetic variance was associated with general combining ability. Maternal and reciprocal effects were significant for two and one characters, respectively. Specific crosses among certain types had higher means than expected based on mid‐parent values for several characters.
