高淀粉玉米与普通玉米的遗传分析

Genetic Analysis on High-starch Maize and Ordinary Maize

以8个早熟高淀粉玉米自交系和8个同型普通玉米自交系,按Griffing完全双列杂交方法4组配,得到28个高淀粉玉米和28个普通玉米杂交组合。经遗传分析,除株高、穗位高外,高淀粉玉米的形态发育与普通玉米相近,从而说明在黑龙江省选育高淀粉玉米种质及杂交种是现实可行的。

8 early maturing and high-starch maize inbred lines and the same types of ordinary maize inbred lines were took as materials to hybridize, and acquired 28 high-starch maize and 28 ordinary maize. The genetic analysis indicated that the form of high-starch maize was similar to the ordinary ones except for plant height and ear height. That was to say to select and breed high-starch maize germplasm and crossbreed in Heilongjiang province was feasible.
