我们采用He-Ne、CO2激光对滇糯稻——云南姚安三角大香糯水稻品种进行诱变育种改良,其目的是要在保持原品种良好特性的前提下,降低植株高度,缩短生育期,提高产量,并扩大种植适应区域。经过连续六年的探索研究和试验,其样品在试验地及原产地都出现了较好宏观表现,并具有基本稳定的遗传。结合实验室和田间试验表现,对激光诱变水稻的作用机理及遗传稳定性进行了分析研究。 We used He-Ne and CO2 laser to mutagenize Diannuo rice-Daxiang glutinous rice varieties in Yao’an triangle of Yunnan province. The purpose is to reduce plant height, shorten the growth period, Increase production and expand plantings to adapt to the area. After six years of exploration and experiment, the samples showed good macro performance both in the experimental site and the place of origin, with a basically stable inheritance. Combined with laboratory and field experiments, the mechanism and genetic stability of laser-induced rice were analyzed.
