摘　　要：【目的】淡白叶水稻作为有色稻,在稻田景观布置扮演着重要的角色,阐述淡白叶稻的选育过程,对其特征特性、遗传生理和品质等进行研究,为淡白叶稻的利用提供依据。【方法】以淡白叶突变体及其野生型黄华占为试验材料,对其进行正反交实验,同时测定其全生长发育时期的叶绿素含量,并对其进行指纹图谱鉴定。淡白叶突变体与野生型黄华占正反交,其F_(1)代均为绿色表型,其F_(2)代出现淡白叶和绿叶两种类型。【结果】卡方检测分析表明淡白叶突变体属于单基因隐形突变。叶绿素含量测定表明,在早期的营养生长阶段淡白叶突变体与黄华占存在显著差异,而在后期的生殖生长阶段两者无明显差异,同时淡白叶突变体的小区产量也可达到黄华占的86%。【结论】淡白叶突变体的叶色变化对其产量影响不大,淡白叶突变体可作为有色稻育种应用的重要资源。[Objective]As a type of colored rice,light-white-leaf rice plays an important role in the landscape layout of rice fields.This research introduced the selection process of light-white-leaf rice,its characteristics,genetic physiology and quality,which can provide reference for the utilization of the rice.[Methods]The light-white-leaf mutant(LWLM)and its wild-type Huang Huazhan(HHZ)were used as the test materials to conduct positive and negative cross experiments.During the experiments,the chlorophyll content of the whole growth period was measured,and the fingerprint was identified.The positive and negative cross experiments showed that there waas a green phenotype in its F_(1) generation,and there were two types of light white leaves and green leaves in its F_(2) generation.[Result]A Chi-square test showed that LWLM was a single-gene recessive mutation.The determination of chlorophyll content showed that there was a significant difference between LWLM and HHZ in the early vegetative growth stage,however,there was no significant difference between the two in the later reproductive growth stage.Meanwhile,the plot yield of LWLM reached 86%of that of HHZ.[Conclusion]The leaf color change of LWLM exerted little effect on its yield,which indicated that LWLM could be used as an important resource for colored rice breeding.
