摘  要:
2010年研究不同种植地点对来源于一个育种材料的玉米单倍体自然加倍率的影响。结果表明:不同地点种植玉米单倍体自然加倍率有明显差异,甘肃春季播种玉米单倍体加倍率最高,其次为海南冬季种植,北京春播种植加倍率最低。甘肃春季播种和海南冬季播种比其他地点种植更有利于玉米单倍体自然加倍。

摘  要:
Haploids induced from one maize material was used to study the doubling rate in different planting places.The results indicated that the natural doubling rate of the maize haploid were different among these planting places,the doubling rate of the Spring planting in Gansu was the highest,the winter planting in Hainan was in the next place,the doubling rate of the Spring planting in Beijing was the lowest.The Spring planting in Gansu and the winter planting in Hainan would be better options for haploid doubling.
