采用父母本１１０的行比，研究了不同行母本植株在不同气候条件下接受花粉量和产量结构的变化及其相互关系．结果表明：母本行植株接受花粉量，晴天大于阴天，阴天大于雨天；南风时，靠南边行的大于靠北边的；离父本行越近的越大于离父本行远的．母本单株有效果数、每果粒数和单株产量，离父本行越近的其值越高，单株阴果数和千粒重则相反．母本行植株接受花粉量与单株有效果数、每果粒数和单株产量呈极显著正相关，与千粒重呈显著负相关．制种行比雨季以１２～３人为宜，在干旱季节可加到１３～４
Using the ratio of parents 110, we studied the changes of pollen quantity and yield structure under different climatic conditions in different rows of maternal plants and their correlations. The results showed that the maternal plants received more pollens than the cloudy ones in sunny days and cloudy days, while in the south winds, the southern ones were larger than the north ones. The closer the neighbors were, the more they were away from their parents. The number of fruit per plant, the number of fruit per plant and the yield per plant, the higher the value of the parent plant line closer to each other, the number of fruit per plant and 1000-grain weight is the opposite. There was a significant positive correlation between the number of pollen per plant and the number of fruit per plant, the number of per plant per plant and the yield per plant. There was a significant negative correlation between the number of pollen per plant and the weight of 1000-grain weight. Seed production line than the rainy season to 12 to 3 is appropriate in the dry season can be added to 13 to 4
