Abstract
六個分屬於Spanish、Valencia及Virginia三種植物型（各2品系）之落花生品系爲材料，進行6×6全互交（不包括反交）分析，探討F1，世代莢果及籽粒性狀的組合力及雜種優勢。結果顯示：十項性狀均以累加性作用較重要，但仍有七項性狀其非累加性作用仍佔重要成份。
Six peanut (Arachis hypogaea L.) lines, were selected to represent a wide range of genetic diversity and intermated using a half-diallel mating design. The lines included two Spanish types, P1 240553 and P1 261946; two Valencia types, NC Acc. 17127 and PI 407454, and two Virginia types, Bolivia 2 and PI 203396. Parents and 15 F1 hybrids were field evaluated to study the combining ability and heterosis for pod and seed traits. Combining ability analysis showed that both general and specific combining abilities (GCA and SCA) were significant for all traits with the exception of the SCA for full-seed ratio, pod width, and seed width.
