闽稻3号在1977年早季测产试种中,表现出株态优良,综合性状好、耐肥、高产等优点。种植0.2617亩,实收干谷329.5斤,折合亩产1259斤,居测产的三个品系的首位。现简介如下,供进一步试种示范参考。一、来源与选育经过:闽稻3号是1974年8月间,以691(1)为母本与卷叶稻(691辐射后代突变株,内外颖不正常,花药瘦小花粉量少,叶片内卷似圆筒型)为父本进行人工杂交,获得一粒种子。当年冬季在海南岛培育 F_1,株型正常。1975年晚季在福州(本所)种植 F_2,株型产生分离,据田间调查500个单株,株型正常的400株,卷叶的100株,比例为4:1。我们从中选择20个正常型的优良单株,当年冬季在海南岛加代培育 F_3,其中11个单株多下来的种子,将其混
Min-3 No. 3 in early 1977 test yield test showed excellent plant state, good overall performance, resistance to fertilizer, high yield and so on. Cultivate 0.2617 mu, harvest dry valley 329.5 kg, equivalent to 1259 kg per mu, measuring production of the first three strains. The brief introduction is as follows, for further trial demonstration reference. First, the source and breeding after: Fujian rice 3 is in August 1974, to 691 (1) as the female parent and leafy rice (691 radiation offspring mutant strains, internal and external Ying is not normal, less thinner anther thinner, leaves Rolling like a cylinder-type) as the male hand-hybrid, get a seed. In the winter, F_1 was cultivated in Hainan Island and its plant type was normal. In the late 1975, F_2 was planted in Fuzhou (our institute), and plant types were segregated. According to the field survey, 500 plants, 400 plants of normal type and 100 plants of curly leaves were obtained, with a ratio of 4: 1. We select 20 normal type of fine single plant, when the winter in Hainan Island and F_3 generation, including 11 more than the seed of the plant, the mixed
