一、引言当前,水稻品种提纯复壮技术,以“单株(穗)选择、分系比较、混系繁殖”方法,却通过建立“株(穗)行圃、株(穗)系圃、原种圃”的三圃制生产原种,被认为最合理、有效。我认为,水稻品种是个大群体,三圃提纯技术不利于将一个群体中的优良个体尽可能多地保存下来,而且在生产实践中,建立数百至上千个株(穗)行圃,数十至数百个株(穗)
I. INTRODUCTION At present, the technology of purifying and rejuvenating rice varieties is based on the methods of “single plant (panicle) selection, partial system comparison and mixed breeding”. However, Nursery "three nursery production of the original species, is considered the most reasonable and effective. In my opinion, rice varieties are a large group. The purification techniques of Sanpu are not conducive to preserving the best individuals in a group as much as possible. In the practice of production, hundreds to thousands of plantations (spikes) To hundreds of strains (spike)
