| 摘 要： | 对大麦12个农艺性状的相关分析表明,穗粒重受多种因素影响,早代应注意对穗长的选择。株高、生育期对产量影响较小,可单独进行选择。大麦优良组合,应选第一主成分值大、第四主成分值小的组合,并放宽第二、三主成分值的取值标准。 |

| Abstract: | Twelve agronomic traits of two-rowed barley(Hordeum distchon)were studied with simple correlation,canonical correlation and principal component analysis.The results showed that kernel weight per spike is influenced by many factors and the selection for spike length should start in early generations.Plant height and days to maturity have less impact on yield and can be selected independently.For the selection of excellent cross com- binations,focus should be placed on combinations with large first principal component value and small fourth principal component value.The values for the second and third principal components may be widened. |
