摘要: 比较了12个同源四倍体大麦原种与其二倍体亲本在每穗小穗数、每穗实粒数、结实率、千粒重、穗重和蛋白质含量上的差异。结果表明四倍体与二倍体在上述性状上存在着极显著的差异。在每穗小穗数、每穗实粒数、结实率和穗重上,四倍体不如二倍体;而千粒重和蛋白质含量上,四倍体则优于二倍体。四倍体原种间在上述性状上也表现出明显的差异,原种内不同单株在每穗实粒数和结实率上亦有很大在变幅。选择对部分原种的结实率有一定的正效应。

Abstract: Comparison of 12 autotetraploid barley original varieties with their diploid parents in spikelets per ear, seed-set, 100-grain weight, grain weight per ear and protien content has been done.The results showed significant difference in characteristics mentioned above between tetraploids and diploids.In spikelets per ear, grains per era, seed-set and grain weight per ear, tetraploids were inferior to diploid parents, and superior to diploid parents in 1000-grain weight and protein content.Among various tetraploid original varieties, there was obvious difference in mentioned above, and so was in grains per ear and seed-set among different plants of the same tetraploid original variety.Selection for seed-set showed some effect in a few tetraploid original varieties.
