通过1989~1992年3批单株测交组合的配制和鉴定,初步揭示了甜菜有粉系早代配合力选择的方法、效果和存在的问题。选育出一般配合力较高、经济性状较优的甜研4号轮-24、A_(?)-24轮-24和81G—06轮-16等优良株系4个,高配合价基因型20余个,以及新的一轮群体3个,其中甜研4号一轮群体在主要性状方面有明显增益:根产量提高18.30%、含糖率增加2.9度,产糖量提高54.3%,褐斑病病情降低0.21级。该研究为开展甜菜配合力育种提供了一定的积累。
Through the preparation and identification of three batches of crossbreeding combinations from 1989 to 1992, the methods, effects and existing problems of the selection of combining ability of early lines of powdery millet were explored. The results showed that there were 4 good lines including sweet round 4 -24, A_ (-24) -24 and 81G-06 round -16 with high general combining ability and good economic traits, More than 20, and a new round of three groups, of which a round of Sweet Institute No. 4 significant gains in the main traits: the root yield increased 18.30%, the sugar rate increased 2.9 degrees, sugar yield increased 54.3%, brown The disease is reduced by 0.21 level. The research provided a certain accumulation for the development of sugarbeet combining ability.
