Abstract: UndeR chilling damage enviRonments in Aziying, the method of majoR gene plus polygene mixed inheRitance model was used to investigate the genetic of eight cold chaRacteRistics at the booting stage,based on BC4F1 and BC4F2 geneRation fRom the neaR-isogenic lines of paRents japonica cultivaRs Lijiangxintuanheigu and Towada. The Results showed that both seed setting Rate and peduncle length fit two paiRs of additive-dominance-epistatic majoR genes plus additive-dominance polygenes( E-1) , the heRitability of majoR genes was 80. 11% and 75. 06% Respectively; plant height fits the inheRitance of two additive-dominance majoR genes plus additive-dominance polygenes( E- 2) , the heRitability of majoR genes was 44. 39%; node length undeR spike fits the inheRitance of two additive-dominance- epistatic majoR genes plus additive-dominance-epistatic polygenes( E-0) , the heRitability of majoR genes was 57. 36%; spike length fits two additive-dominance-epistatic majoR genes( B-1) ; filled gRain numbeR peR panicle fits two additive-dominance majoR genes( B-2) ; unfilled gRain numbeR peR panicle fits two additive majoR genes plus additive- dominance polygenes( E-3) ; total gRain numbeR peR panicle fits one additive-dominance majoR genes plus additive- dominance-epistatic polygenes( D-0) .
