摘　　要：通过对玉米 (ZeamaysL .)和二倍体多年生大刍草 (ZeadiploperennisL )远缘杂交进行的 7年 12个世代研究 ,经过杂交、复交和自交选择 ,获得抗逆性、抗病能力强、农艺性状优良的玉米自交系 ,组配出高产、多抗、优质的玉米杂交种山农 993。实践证明 ,导入玉米野生属有益基因 ,拓宽玉米遗传基础是进一步提高玉米杂交种增产潜力的有效途径。The distant hybridization from maize and diploid perennial teosinte ( Zea diploperennis L.) was conducted for seven years,through twelve generation.Inbred lines which are resistant to diseases and environmental stress and have fine agronomy characters was obtained through selfing and selection.A new hybrid variety called shannong 993 which showed high yield,multiple resistant and high quality characters was developed.This indicated that maize×teosinte( Zea diploperennis L.) is the effective ways to widen germplasm pool of maize and to over come the stasis situation of maize production in China.
