利用一代杂种,可以提高大白菜栽培性状的一致性,是增强抗病性,改进品质,获得高产的有效途径。为了尽快地选育出优良的一代杂种及有效地解决制种技术,我们于1963年起开展了大白菜自交不亲和系的选育及一代杂种优势利用的研究。在毛主席革命路线指引下,选育出一批较稳定的自交不亲和系及优良的一代杂种组合。其中一代杂种“青杂早丰”、“青杂中丰”已在当地生产中推广应用。
The use of a generation of hybrids can improve the consistency of Chinese cabbage cultivation traits, which is an effective way to enhance disease resistance, improve quality and obtain high yield. In order to breed excellent hybrids as soon as possible and effectively solve the seed production technology, we carried out in 1963 Chinese cabbage self-incompatibility breeding and generation of heterosis utilization research. Under the guidance of Chairman Mao’s revolutionary line, a group of relatively stable self-incompatibility lines and excellent hybrid generations are bred. One of the hybrids “Zaobao Zafeng”, “Zazhong Zhongfeng” has been popularized and applied in local production.
