【摘要】 本试验研究了九个水稻品种对白叶枯病菌“江陵69l”菌株的成株抗性遗传,进行了抗病基因的等位性测定。结果表明:水稻品种Bulu Patih、Ketan Gondel、Pulut Kemandi、KetanGondopuro、Ketan Bajong和Rathu Heenati对“江陵691”菌株的成株抗性由一个相同或等位的显性抗病基因控制,该基因与全抗品种IR1545-339和DV₈₅的隐性抗病基因独立遗传,而与全抗品种IR28的显性抗病基因为复等位基因;南梗15、早生爱国3号和辛尼斯的成株抗性各由一个显性抗病基因控制,这三个抗病基因彼此独立遗传。更多还原

【Abstract】 The inheritance of adult Plant resistance in nine rice varieties and theallelic relationship of genes for rcsistance to“Jiangling691”Strain of Xantho-monas campestris pv. oryzae were studied. The results indicated that therice varieties Bulu Patih, Ketan Gondel, Pulut Kemandi, Ketan Gondopuro,Ketan Bajong and Rathu Heenati have the same Or allelic dominant gene foradult plant resistance. which is non-allelic to the recessive gene for overallresistance in IR_l545-339 and DV₈₅ and is multiply allelic to the dominant genefor overall resistance in IR₂₈. Nangkeng 15, Wase Aikoku 3 and Zenith eachhave a dominant gene for adult plant resistance. The three genes are non-allelicand segregate independently of each other.更多还原
