苹果杂种的选择包括种子、子叶苗、结果以前的幼龄植株和以后的果实鉴定等。实践与研究说明,杂种实生苗定植前的预选是一个关键。因为这一阶段选择的准确性高低直接关系到育种成效的大小。为了研究选择标准及其与果实等经济性状的相关程度,结合我们的工作实际,参考了一些前人经验,我们对1964、1975、1978年杂交的几批实生苗在定植前进行了性状的预选,并对1964年杂交的植株性状评分在3分以上的实生苗作了相关性分析。
Selection of apple hybrids includes seeds, seedling shoots, the results of previous young plants and subsequent fruit identification. Practice and research show that pre-planting hybrid seedlings pre-selection is a key. Because the accuracy of the selection of this stage is directly related to the size of breeding effectiveness. In order to study the selection criteria and its correlation with the economic traits such as fruit and so on, with reference to some previous experiences, we conducted preliminary character traits of pre-planting seedlings of several batches of seedlings crossed in 1964, 1975 and 1978. , And correlation analysis was made on the seedlings with the plant character score of 3 points or more in 1964 hybridization.
