自六十年代初期起,我场对水稻良种的提纯复壮技术,进行了一些研究。试验证明,系谱鉴定法技术要求虽较高,但效果较好,应该作为国营原(良)种场对良种提纯复壮的主要方法。目前广泛推行的“三圃法”(即选种圃、株系圃、原种圃,或穗行圃、穗系圃、原种圃),就是以单株(穗)的系谱鉴定为主的提纯复壮方法。三圃法的 Since the early 1960s, my field has done some researches on the technology of purification and rejuvenation of rice varieties. Experiments show that pedigree identification method, although the higher technical requirements, but the effect is better, should be used as the original (good) species field of the main method of purification of seed. At present, the “three-garden law” (that is, selection of nurseries, nurseries, nursery gardens, or nursery gardens, spike nurseries, and nursery gardens) is widely based on pedigree identification Purification and rejuvenation methods.
