本研究探讨了兴农西瓜瓜重、瓜数与杂交一代产籽量的相关性。结果表明:春季制种单瓜重与种籽粒数的相关区间在0.4—4.8kg,秋季制种其相关区间在0.4—3.8kg区间内都呈二次指数方程正相关;两季制种单瓜重在0.4—3.0kg区间内产籽量随瓜重增加而近似直线上升;单株产籽量随瓜数的增加而成自然对数方程正相关,其种籽百粒重和质量经方差分析和试验无显著差异。据此结论是:控制瓜重在3.0kg内,主要着眼点是力增结瓜数,以达到增加单位面积产籽量的目标要求。
In this study, we discussed the relationship between the weight and the number of melon in Xingnong Watermelon and the seed yield in hybrid generation. The results showed that the correlation interval between spring single seed weight and seed weight was 0.4-4.8kg, the correlation interval between autumn seed production and 0.4-3.8kg was quadratic exponential equation; The weight of seed in the range of 0.4-3.0kg increased linearly with the increase of melon weight. The seed yield per plant was positively correlated with the natural logarithmic equation with the increase of melon number. No significant difference from the test. The conclusion is: control melon weight within 3.0kg, the main focus is to increase the number of knot in order to achieve the goal of increasing seed yield per unit area.
