在甜瓜抗病育种中,出现了48.2%的单性花率,以后得知是D_(72)远缘杂种后代与一高抗单性花进行了自然杂交而出现的变异,该组合是含笑多抗源后代{〔<含笑出园瓠>α鼠瓜)×海南花蒲〕×丝瓜}×(F_2)包含了五种不同远生态型的遗传基因。表现超亲高抗。 以后对该系经过南繁加代、以一年三代快速选育方式,去劣选优,抗性稳定下来;单性花率也随之提高,现平均在90名以
In melon disease-resistant breeding, there appeared 48.2% of unisexual flowers rate, later known as D_ (72) distant hybrid progeny and a high resistance to the monotypic flower natural hybrid mutation, the combination is smiling The resistant offspring {[ a rat and rat) × Hainan flower Po] × loofah} × (F_2) contains five different far-ecological type of genetic. Super-high-performance anti-performance. After the Department of the South through the generation of the generation to three generations a year of rapid breeding methods, to poor selection, resistance stabilized; unisex rate also increased, the average is now 90
