Abstract

Abstract: 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.

Key words: Maize, Teosinte( Zea diploperennis L.), Distant hybridization, Inbred line, Hybrid
