本试验在保定地区农科所试验场进行。供试品种14个:东红三号、丰抗4号、丰抗8号、丰抗2号、丰抗13号、保3143、津农7535、吕麦669、吕麦562、太原204、廊7804、太原645、78—4020、乐亭1185。随机区组排列,重复三次。对性状遗传参数进行了方差分析,估算结果是:1、小麦穗长遗传力最高,为93.71%,穗粒重遗传力最低,为21.41%。各性状遗传力大小顺序为穗长>株高>千粒重>穗粒数>穗粒重。一般表现有植株性状遗传力大
This experiment is carried out in the experimental field of Agricultural Science Institute in Baoding. The test varieties 14: East Red 3, Feng 4, Feng 8, Feng 2, Feng 13, Paul 3143, Jinnong 7535, Lu Mai 669, Lu Mai 562, Taiyuan 204, Gallery 7804, Taiyuan 645,78-4020, Laoting 1185. Randomized block arrangement, repeated three times. The variance analysis of genetic parameters of traits showed that the results were as follows: 1. The earliest heritability of wheat was 93.71%, and the lowest heritability of ear kernel was 21.41%. The order of heritability of each trait was spike length> plant height> 1000-grain weight> number of grains per ear> grain weight per ear. The general performance of plant traits heritability
