摘要
以有棱丝瓜海大1号、海大2号及其正反交品种为材料,研究其主要性状的遗传规律,揭示其杂种优势情况,为丝瓜的育种提供理论参考。结果表明:海大1号和海大2号杂交后代具有杂种优势这一遗传特性,杂种F1代长势更旺盛,果实的商品性状好,抗病性稍强,尤其是正交F1代的产量高达67 534.5 kg·hm-2,优于其亲本,极具市场竞争力。
Angled luffa （ Luffa acutangula L. ） is a major vegetable gourd in South China. Two angled luffa varities Haida 1 and 2 and the progenies of their reciprocal cross were planted in the garden to evaluate the inheritance of their major traits and their heterosis with a view to provide theoretical reference for heterosis breeding in angled luffa. The results showed that the first filial generation of the cross between Haida 1 and Haida 2 exhibited a genetic trait of heterosis. The F1 progenies grew more vigorous and slightly highly tolerant to diseases and their fruits sold well in the market. The F1 progeny of the direct cross between Haida 1 and 2 yielded 67 534.5 kg · hm^-2, higher than its parents, and hence is very competitive in the market.
