甘兰自交不亲和系的研究和利用

关于甘兰杂种一代利用及其遗传行为的研究是在1971—1979年进行的。以北京早熟、迎春、金早生、斯达哈诺夫卡等品种为材料,选择优良单株连续自交。根据主要经济性状、亲和性、配合力进行选择并共培育出六个优良自交不亲和系。其同共特性是:性状整齐一致,高产并可作为配制一代杂种的优良亲本。利用上述培育的甘兰自交不亲和系及引自上海园艺研究所的黑叶小平头自交不亲和系的材料,进行了160多个组合搭配,从中选育出一个早熟、二个中早熟优良组合。在培育自交不亲和系及选配优良一代组合过程中也研究了甘兰遗传行为。

APPLICATION & RESEARCH OF SELF—INCOMPATIBILITY LINES IN CABBAGE

The study of application of F_1 cabbage hybrid and its genetic behaviours was made in 1971-1979. The superior single plants were selected and selfing continuously with the basic materials namely Peking Early, Welcome Spring, King early and staxanovka. According to the main economic characteristics, compatibility and combining ability, six superior self-incompatible lines were released which are provided with more uniformity, higher yield, and have been used as good parents to produce F_1, hybrids. In addition, using the six self-incompatible lines as indicated above and Black Leaf self-incompatible line introduced from Shanghai Vegetable Research Institute, more than 160 combinations have been made, and one early and two mid-early superior combinations were selected among them. The genetic behaviours of the incompatibility in cabbage has been studied along with the development of self-incompatible lines and combinations.
