An F2 yield trial in peanuts (Arachis hypogaea L.) was conducted in 1978 to evaluate 25 entries in a six replicate randomized complete block design. Entries included progenies from sixteen intrasubspecific cross combinations and their representative parents: seven component lines of two U. S. cultivars, ‘Florunner’ and ‘Florigiant’, and two peanut introductions, ‘Makulu Red’ and ‘486 GKP’.
Progeny and parental performances were determined for eight quantitative traits: yield, fancy pods, meat content, total sound mature kernels, other kernels, extra large kernels, damaged kernels, and 100 seed weight.
Hybridization between adapted and unadapted genotypes led to a reduction in performance characteristics. However, cross populations were identified as having selection potential for improving yield and grade.
