Suwan与我国四大玉米种质的配合力和杂种优势分析

Study on the Combining Ability and Heterosis Between Suwan and Four Major Maize Germplasm of China

采用NCII设计,研究了4个Suwan群体与我国四大骨干自交系的配合力和杂种优势。结果显示:Suwan群体选系有较好的一般配合力,与四大骨干自交系有较高的特殊配合力和较强的杂种优势。其中,Suwan3的选系一般配合力较高,与丹340组配易形成较强的杂种优势。

By using NCII design the combining ability and heterosis between Suwan and four major maize germplasm of China were studied. The results showed that Suwan Germplasm lines have higher general combining ability. There are higher specific combining ability and heterosis between those lines and four major gerplam. The heterosis pattern between lines from Suwan 3 and Dan 340 were discussed.
