本文研究了国外引进的六个抗病材料Zenith,Pelita I/1、DV-86、DZ-78、DV-85和BJ1对白叶枯病强菌株KS-8-4的抗病性遗传,试算了和育种有关的遗传参数,结果表明:Zenith和BJ1对KS-8-4的抗性是由一个隐性主效基因控制的,Pelita I/1的抗性是由一个显性主效基因控制的,而DV-86、DZ-78和DV-85的抗性均是由一个显性上位基因和一个隐性基因控制的。抗病性狭义遗传力多数在70％以上,预期抗病性早代选择较易收效。 In this paper, we studied the inheritance of disease resistance of the resistant strains Zenith, Pelita I / 1, DV-86, DZ-78, DV-85 and BJ1 to the bacterial blight strain KS-8-4. The genetic parameters related to breeding showed that the resistance of KS-8-4 to Zenith and BJ1 was controlled by a recessive major gene, and the resistance of Pelita I / 1 was controlled by a dominant major gene While the resistance of DV-86, DZ-78 and DV-85 was controlled by a dominant epistasis and a recessive gene. Narrow sense of resistance Most heritability in more than 70%, the early resistance is expected to choose more effective disease-resistant.
