本文研究了全同胞轮回选择和混合选择对玉米群体主要经济性状配合力的改良效果,结果表明:两稚选择方法对群体主要经济性状的配合力都有一定的改良效果,并以对一般配合力的改良效果较大;而且全同胞轮回选择的改良效果明显优于混合选择;经4次重组的基础群体,多数经济性状一般配合力的改良进展明显大于经2次重组的基础群体。
In this paper, we studied the improvement effect of all-sibling recurrent selection and mixed selection on the combining ability of main economic traits in maize population. The results showed that both selection methods had some improvement effects on the combining ability of main economic traits, , And the improvement effect of all-round recurrent selection was better than that of mixed selection. After 4 times recombination, the improvement of general combining ability of most economic traits was significantly greater than that of the 2-way recombination basic population.
