采用60 Coγ射线 2 0 0Gy辐照处理 (晚粳“丙 92 1 2 4” 晚糯“绍糯选”)F2 干种子 ,经多代筛选获得晚糯稻突变体ZH2 0 6。ZH2 0 6经试种表现为产量高、籽粒大且品质优。 2年、2地区域试验比对照平均增产 9 4% ;籽粒较双亲明显增大 ,千粒重较母本丙 92 1 2 4重 4 1g ,较父本绍糯选重 3 6g ,千粒重达 30g以上。糯性优于对照祥湖 84,更优于亲本绍糯选。 2 0 0 3年通过浙江省农作物品种审定委员会审定 ,命名为“浙糯 36” ,成为近 2 0年来在浙江省 (市 )级晚粳糯稻区域试验中 ,增产幅度和籽粒均达到最大的晚糯稻审定品种。该品种的选育成功表明辐射诱变同步改良糯稻多个性状的可能性与有效性。
The F2 dry seeds of late rice “Diannuo” were digested with 60Co γ-rays at 200 Gy, and the late-glutinous rice mutant ZH2 0 6 was obtained through multiple generations of screening. ZH2 0 6 The performance of the test is high yield, large grain and good quality. 2 years, 2 regional trials than the control average yield of 9 4%; grain than their parents increased significantly, the 1000-grain weight than the parent C 92 1 2 4 weight 4 1g, compared with the father Shao glutinous selection weight 36g, 1000-grain weight of 30g or more. Waxy better than the control Xiang Lake 84, better than the parent Shao waxy election. In 2003, it was approved by Zhejiang Province Crop Variety Approval Committee and named as “Zhejiang Glutinous Rice 36”. It became the late growth rate and kernel of late japonica glutinous rice in Zhejiang Province in the recent 20 years Sticky rice validation varieties. The successful breeding of this variety indicates the possibility and effectiveness of simultaneous improvement of multiple traits of glutinous rice by radiation mutagenesis.
