摘要
对203份小麦的农艺性状进行鉴定和研究。结果表明,种质资源存在丰富的遗传多样性,其中穗数、穗粒数、千粒重和产量的变异系数分别为12.6%、9.3%、12.2%和14.7%。千粒重和穗粒数与产量的相关系数达极显著水平。长穗多粒特性的多穗型材料具有较高的产量潜力。筛选出28份可重点利用的矮秆、大粒、多粒、高产、优质类型材料。
Agronomic characters were evaluated for 203 wheat germplasms.The results showed that the coefficients of variance of spikes per plant,kernels per spike,1000-grain weight and yield were 12.6%,9.3%,12.2%and 14.7%,respectively.Agronomic traits had greater genetic diversity.1000-grain weight and kernels per spike had extremely significant correlation with yield.Multi-spike cultivars with long spike and many seed had higher yield potential.28 germplasms were screened with the advantages of short plant,big seed,many seed,high yield and high protein.All these accessions could be used as resources in wheat breeding.
