摘要
为利用好小麦资源材料,对18份临汾系列小麦品种的农艺性状和品质性状等19个性状进行分析。相关分析结果表明,农艺性状与品质性状间有着复杂的相关关系,有10对性状表现为显著或极显著相关,有34对性状表现为显著或极显著偏相关。聚类分析结果表明,供试材料从农艺性状和品质性状可聚为3类,Ⅰ1,Ⅰ2,Ⅱ2和Ⅲ类群在育种中可以作为高产材料加以应用;Ⅰ2和Ⅲ类群可以作为矮秆抗倒材料加以应用;Ⅱ3类群可以作为改良穗部特性材料加以应用;Ⅰ1,Ⅱ1和Ⅲ类群可以作为优质材料加以应用;Ⅰ2类群可作为改良粒质量材料加以应用。
To make good use of wheat breeding resources,agronomic and quality characters of 18 Linfen series wheat were analyzed.The correlation analysis showed that there were complex relations between agronomic and quality characters.There was significant or extremely significant correlation between 10 pairs of characters.There was significant or extremely significant partial correlation between 34 pairs of characters.By clustering analysis,the results showed that all tested materials from agronomic and quality characters were divided into three classes.Class Ⅰ1,classⅠ2,classⅡ2 and class Ⅲcould be used as high material of breeding.ClassⅠ2 and classⅢ could be used as dwarf lodging-resistant wheat materials,classⅡ3 could be used as improved ear characteristics.ClassⅠ1,classⅡ1 and class Ⅲ could be used as quality breeding materials.ClassⅠ2 could be used as grain quality materials.
