坚持种植鉴定,是严格杂交稻种子质量把关的一项重大措施。我省从1982年就采用了这种方法,并制订了“杂交水稻亲本及杂交种田间种植检验操作规程”(以下简称“杂鉴规程”)。通过在杂交水稻“三系”亲繁及杂交制种的整个生育进程中,重点在苗期、抽穗开花期和成熟期,对植株形态特征及生物学特性进行田间检验,鉴别其异品种和变异株。并结合花粉镜检、套袋自交、隔离种植等检查鉴定不育系的不育度和不育株率。从而有效地鉴定纯度,保证了杂交稻种子质量。根据杂交水稻“省提、地繁、县制”的要求,由省种子公司负责杂交水稻亲本提纯基地种子的田间复验和收种后的种植鉴定。以地(市、州)为单 Adhere to the identification of planting is strictly checks the quality of hybrid rice is a major measure. This method has been adopted in our province since 1982 and formulated the “Operational Procedures for Field Planting Inspection of Parents and Hybrids of Hybrid Rice” (hereinafter referred to as “Miscellaneous Procedures ”). Through the whole process of inbreeding and hybrid seed production of hybrid rice “three lines ”, the focus was on the seedling stage, heading and flowering stage and maturity stage, and the morphological characteristics and biological characteristics of the plants were tested in the field to identify their heterosis And mutant strains. Combined with pollen microscopy, bagging selfing, isolation and planting inspection sterile CMS lines and sterile rate identification. In order to effectively identify the purity, to ensure the quality of hybrid rice seeds. According to the requirements of hybrid rice “provincial mention, to the traditional, county ” requirements, the provincial seed companies responsible for the hybrid rice parent purification base seed field retest and planting after planting identification.
