为了缩短甜菜多倍体育种年限,加速繁殖四倍体早代育种材料,尽快地选育出优良的多倍体品种提供生产应用,几年来,我们充分利用我国土地辽阔、南北气温相差较大的有利条件,进行了南繁培育母根的试验,取得了良好的效果。自一九七五至一九七八连续四年,我们在湖北省武汉市(中国农业科学院油料作物研究所农场)进行了甜菜四倍体的南繁工作,南繁的材料绝大部分为需要加速镜检提
In order to shorten the life span of beet polyploidy, accelerate the breeding of tetraploid early breeding materials, and to breed fine polyploid varieties as soon as possible to provide production and application, in the past few years, we make full use of the vast land in our country and large difference in temperature between north and south Favorable conditions, the South Fan breeding mothers of the test, and achieved good results. For four consecutive years from 1975 to 1978, we carried out Nan Fan’s work of tetraploid beet in Wuhan, Hubei Province (farm of the Institute of Oil Crops, Chinese Academy of Agricultural Sciences). Most of the materials in Nan Fan are needed Accelerated microscopic examination
