| 摘 要： | 为选育籽粒灌浆和脱水速率高的品种,选用9份K10改良自交系,按格列芬双列杂交方法Ⅳ设计,对自交系籽粒灌浆速率、脱水速率、穗轴脱水速率及苞叶脱水速率配合力进行分析。结果表明:用9份自交系的配合力自交系间有较大差异。自交系4、自交系3籽粒灌浆速率、脱水速率的一般配合力均较高;自交系8籽粒灌浆速率一般配合力较高,脱水速率一般配合力居中;自交系9籽粒灌浆速率一般配合力较低,脱水速率一般配合力较高;自交系2、1、7籽粒灌浆、脱水速率一般配合力均较低。用来改良K10的9份材料中,国外杂交种和欧洲群体改良灌浆脱水性状的效果较好,丹598、丹340、瑞德群体、郑58不理想。

| Abstract: | In order to breed the varieties with high grain filling and dehydration rate, taking nine K10 inbred lines as materials,according to Gregory Fen diallel cross method IV, the combining ability of grain filling rate and dehydration rate,dehydration rate of cob and bract were analyzed. The results showed that there was lager difference of combining ability between 9 inbred lines. General combining ability of grain filling rate and dehydration rate of inbred line 4 and inbred line 3 were high;general combining ability of grain filling rate of inbred line 8 was high,general combining ability of grain filling rate inbred line 9 was low but its general combining ability of dehydration rate was high;combining ability of dehydration rate and grain filling rate of inbred lines 2, 1,7 were low. Among 9 materials of modified K 10, dehydration character of abroad hybrid and European Group were better, and Dan 598, Dan 340, Reed group,Zheng 58 were not ideal. |
