一、野败型,冈型不育系与 IR_(36)配制的各组合产量比较结果IR_(36)是近两年从国际水稻研究所引进的新品种,它具有对多种病虫的抗性。1976年7—8月我们用 IR_(36)为父本,同野败型 V_(20)A、金南特 A、冈型朝阳1号 A、青小金早 A、C 系统南新 A 转育的梅丰选 A 进行了测交。同年冬在海南陵水县播种。发现 IR_(36)对以上三种类型的不育系都具有良好的恢复能力。如 U_(20)A×IR_(36),结实率高达90.9%,在5×7寸密度下,
First, wild-type, wild-type sterile line and IR_ (36) of the combination of the results of the results of the combination IR_ (36) is nearly two years from the International Rice Research Institute introduced new varieties, it has a variety of pests Sex. From July to August in 1976, we used IR_ (36) as the paternity to transfer to wild type V_ (20) A, Jinnant A, Gangchaoyang No.1, Qingxiaojinzao A, C system Nanxin A Meifeng election A was submitted. The same year in Lingshui County, Hainan sowing. It was found that IR_ (36) had good recovery ability for the above three types of CMS lines. Such as U_ (20) A × IR_ (36), seed setting rate as high as 90.9%, at 5 × 7-inch density,
