为使韭菜利用雄性不育系进行杂交制种能够取得较高的种子产量提供科学依据，我们于1989年开始利用我所选育的“石汉3A”早代不育试材，与早代自交系开展了杂交制种方面的研究。现将该技术研究介绍如下。一、直播与移栽对种子产量的影响直播试验于4月22日播种，每m2播种量...
In order to provide a scientific basis for the higher seed yield of Chinese chives by using male sterile lines for hybrid seed production, we started using the “Shi Han 3A” Intersection carried out hybrid seed production research. Now the technical research described below. First, the impact of direct seeding and transplanting on seed yield Direct seeding tests were sown on April 22, each seeding ...
