湖北光周期敏感核不育水稻(Hubei Pho-toperiod-Sensitive Genic Male-Sterile RiceHPGMR)简称光敏感核不育水稻。该材料在1985年10月由农牧渔业部主持通过部级鉴定,原始材料农垦58突变株为粳型。经研究表明,这是一种受核内基因所控制的不育材料,具有育性转换的特性。诱导育性转换的主导因子是日照长度,调节日照长度,可以控制花粉的发育,从而形成育性的变化。 在北纬30°38′的武汉地区自然日照条件下,1986年分三期播种,以品种农垦58为对照。应用扫描电子显微镜对剑叶表面结构进行比较观察,並结合成
Hubei Pho-toperiod-Sensitive Genic Male-Sterile Rice (HPPGMR) is called Photo-sensitive Genic Male Sterile Rice. The material was appraised by Ministry of Agriculture, Animal Husbandry and Fishery in October 1985 through ministerial level. The original Nongken 58 mutant was japonica. The study shows that this is a kind of sterile material controlled by the nuclear gene, with fertility conversion characteristics. The dominant factor inducing fertility transformation is the length of sunlight, adjusting the length of sunlight and controlling the development of pollen to form the change of fertility. Under the condition of natural sunlight in Wuhan of latitude 30 ° 38 ’north, sowing was carried out in three phases in 1986 and the cultivar Nongken 58 was taken as control. Application of scanning electron microscopy of the surface structure of the flag leaf were observed and combined into
