贵州地方血缘自交系配合力研究

Study on Combining Ability of Several Maize Inbreds with Guizhou Local Strain

用自选及从省内外引进的13个自交系(其中有5个自交系具有贵州地方血缘),按Griffing完全双列杂交方法四组配78个杂交组合,进行了田间试验。估算了这些自交系产量性状的一般配合力效应。结果表明,自交系大013﹑交51、5003的一般配合力较高。

maize inbreds developed by our institute or introduced from Guizhou or other domestics regions were made 78 cross combinations according to Griffing (1956)'s method 4.5 inbres of them were with Guizhou local strain. Field experiment was conducted. The general combining ability effect (GCA) was estimated. The results showed that GCAs of inbred Da013, Jiao51 and 5003 were high.
