Abstract
本研究利用二個大粒型(Virginia Bunch type)與二個小粒型(Spanish type)落花生雜交組合之F2族羣及其四個親木爲材料，於臺中霧峰及雲林崙背進行田間試驗，估算莢果與籽粒性狀之遺傳率、基因型相關及外表型相關，藉以鑑定此二雜交組合提供選拔大粒、飽滿、豐產落花生新品系之可能潛力。試驗結果顯示：兩個F2族羣之成熟莢果數、成熟莢果重、飽滿籽粒重、莢果長、莢果寬及籽粒寬等性狀之平均值約略相近。Two crosses between large-seeded Virginia Bunch type and small-seeded Spanish type peanuts were evaluated to determine the potential for selecting prominent cultivars. Heritabilities, phenotypic and genotypic correlations were determined for pod and seed traits at two locations. Two crosses had similar number of mature seed, weight of mature seed, weight of well-filled seed, pod length, pod width and seed width. Cross of U-5×Tainung 5 had higher number and weight of mature pod, and less number of well-filled seed and seed length than Tainan Sel. 9 ×Nakate Yataka. Heritability estimates for pod and seed traits were moderate to high over crosses and locations.
