用花粉管通道法将几种植物总DNA片段导入小麦，对变异后代5个农艺性状的遗传力、遗传变异系数及性状间的相关系数进行了估算。结果表明：株高的遗传力最大，其次为千粒重和穗长。每穗粒数和每株穗数的遗传力最小。遗传变异系数以每株穗数和千粒重最高。在相关系数方面，株高与千粒重、株高与每株穗数、穗长同每穗粒数都有极显著的遗传型正相关；株高与每穗粒数、穗长与每株穗数、每株穗数与每穗粒数、每株穗数与千粒重4对性状间存在高度负相关。本文还对这些结果在小麦育种中的应用及意义进行了探讨。 Several total plant DNA fragments were introduced into wheat by pollen tube channel method, and the correlation coefficients between heritability, genetic variation coefficient and traits of five agronomic traits were estimated. The results showed that the heritability of plant height was the largest, followed by 1000-grain weight and spike length. The heritability of grains per spike and panicle per panicle is the smallest. The coefficient of genetic variation was the highest in spikes per panicle and 1000-grain weight. In terms of correlation coefficient, there was a significant genetic positive correlation between plant height and 1000-grain weight, plant height and panicles per panicle, panicle length and grain number per panicle. Plant height and grain number per spike, panicle length and panicles per panicle , There was a highly negative correlation between the number of panicle per panicle and the number of panicles per panicle, the number of panicle per panicle and the number of 4 traits per 1000-grain weight. The paper also discussed the application and significance of these results in wheat breeding.
