摘　　要：通过对３个四倍体材料（４ｎ）和４个二倍体材料（２ｎ）配制测交组合１２个，进行配合力分析，优选出一般配合力最强的吉３３４（４ｎ）和７４２／２（２ｎ）两个亲本。The combining abilities of 12 crossings made from three tetraploid materials(4n) and four dipliod materials(2n) have been measured. From 742/2(2n) and Ji-334(4n), the parents of the highest combining abilities, the crossing ND9016 which is of high heterosis has been made.
