用不同单性结实程度的品系间不完全双列杂交的后代和单性结实与非单性结实品系间杂交的F_1、F_2和B_1代研究了腌制黄瓜单性结实的遗传。单性结实的遗传可用三个独立的、具有加性作用的同分异构主基因以及纯合子-杂合子型的非等位基因互作来解释。已经发现了控制单性结实、雌性和有刺/有毛果实性状的基因之间存在联系的迹象。单性结实品种选育的后果进行了讨论。
The inheritance of parthenocarpy in the pickling cucumber has been studied with progenies of an incomplete diallel cross between lines with different degrees of parthenocarpy and with two sets of F1, F2and B1of crosses between parthenocarpic and non-parthenocarpic lines. The inheritance of parthenocarpy could be explained by three independent, isomeric major genes with additive action, together with a non-allelic interaction of the homozygote-heterozygote type. Indications have been found for linkages between genes that govern parthenocarpy, femaleness and the spined/hairy fruit character. Consequences for breeding parthenocarpic varieties are discussed.
