“提纯复壮”是我国五十年代提出的一种良种繁育方法。“提纯”就是从混杂的群体中,选择那些符合良种原有的典型性植株。“复壮”则是使已经或开始退化的品种恢复或基本恢复它们原来的健壮情况和生产能力。两者结合起来就可以较好地保持品种的纯度和生产能力。 “Purification and Rejuvenation” is a breeding method proposed by China in the 1950s. “Purification” is from the mixed population, select those that meet the original plant typical. Rejuvenation restores or substantially restores the original robustness and productivity of varieties that have or begin to degenerate. The combination of the two can be better to maintain the purity of varieties and production capacity.
