苦荞麦主要农艺性状遗传浅析

试验结果分析表明，苦荞麦株高、千粒重等遗传力较高，早代进行选择效果明显；株粒重等遗传力低，应放宽选择标准，增加选择世代。株粒重虽然与产量高度相关，但遗传变异系数较小，直接选择效果差。可通过选择株高、株粒数和千粒重来达到提高株粒重的目的。

Buckwheat Main Agronomic Traits Genetic Analysis

The experiments result showed that buckwheat plant height, weight of one thousand grains etc, have high heredity ability, early generation selection have obviously results; the grainsweight of one plant have low heredity ability. It should be lower the selection criteria, increasing generations for selection . Although the grains weight of one plant and yield have high relevant, but genetic variation coefficient is smaller, direct select have lower effect, it should be though select plant height, weight of one thousand grains the purpose of improve weight of plant.
