摘要
为利用好小麦资源材料,对19份绵麦系列小麦品种(系)的农艺性状和品质性状等15个性状进行分析。结果表明,农艺性状与品质性状间有着复杂的相关关系,有13对性状表现为显著或极显著相关,有23对性状表现为显著或极显著偏相关。产量与8个农艺性状的关联系数的序次为:基本苗>千粒重>穗粒数>容重>株高>最高苗>生育期>有效穗;产量与6个品质性状的关联系数的序次为:稳定时间>最大阻力>籽粒蛋白>面积>吸水率>湿面筋;蛋白质与9个农艺性状的关联系数的序次为:最高苗>有效穗>基本苗>穗粒数>产量>容重>千粒重>株高>生育期;稳定时间与9个农艺性状的关联系数的序次为:容重>最高苗>产量>生育期>有效穗>千粒重>株高>基本苗>穗粒数;面积与9个农艺性状的关联系数的序次为:基本苗>穗粒数>千粒重>产量>株高>最高苗>有效穗>生育期>容重。供试材料从农艺性状和品质性状可被聚为三类,第Ⅰ2、Ⅰ3、Ⅰ4类育种时可以作为高产材料加以应用,同时Ⅰ3和Ⅰ4类群育种时可以作矮杆材料加以运用;Ⅰ1和Ⅰ4类群育种时可以作为优质品质材料加以运用。第Ⅱ类育种时可从粒重方面加以应用;第Ⅲ类从优质矮杆材料加以应用。
In order to make good use of wheat breeding resources,agronomic and quality characters of 19Mianmai-series wheat were analyzed.The correlation analysis showed there were complex relations betweenagronomic and quality characters.There was significant or extremely significant correlation between 13 pairs ofcharacters.There was significant or extremely significant partial correlation between 23 pairs of characters.The order of 8 agronomic characters influencing yield was basic seedling number 〉1000-kernel weight〉 kernels per ear 〉test weight 〉plant height 〉maximum seedling number 〉growth period 〉ears per hm^2.Theorder of 6 quality characters influencing yield was stability time 〉maximum resistance 〉kernel protein content〉 extension area 〉water absorbing rate〉 wet gluten content.The order of 9 agronomic charactersinfluencing kernel protein content was maximum seedling number〉 ears per hm^2 〉basic seedling number 〉kernels per ear〉 yield 〉test〉 weight〉 1000-kernel weight 〉plant height〉 growth period.The order of 9agronomic characters influencing stability time was test weight 〉maximum seedling number 〉yield〉growth period 〉ears per hm^2 〉1000-kernel weight 〉plant height〉 basic seedling number〉 kernels per ear.Theorder of 9 agronomic characters influencing extension area was basic seedling number 〉kernels per ear 〉1000-kernel weight〉 yield 〉plant height〉 maximum seedling number 〉ears per hm^2〉 growth period〉 test weight.By clustering analysis,all tested materials from agronomic and quality characters were divided intothree classes.ClassⅠ2,classⅠ3 and classⅠ4 could be used as high material of breeding,classⅠ3 and classⅠ4could be used as dwarf wheat materials,classⅠ1,class Ⅰ4 could be used as quality breeding materials.ClassⅡ could be used as grain-weight materials.Class Ⅲ could be used as quality dwarf wheat materials.
