【摘要】 在双桥公社、黑庄户大队病区进行了六年抗条纹叶枯病鉴定和品种选育,其结果:（1）籼稻比粳稻具有较强的抗性,籼粳稻和水陆稻杂交后代,大都较粳粳交后代抗病。（2）鉴定出籼稻塔杜康（Todukan）、特特普（Tetep）、C_4-63、窄叶青8号、IR26、IR8以及粳稻烟锦糯（陆稻农林糯39）、中国31等品种具有较强的抗性,可用作抗源亲本。（3）在自然选择与人工选择相结合的条件下,加大了选择压力,在导入抗性基因的株系中,选育了抗病性强、丰产性较好的中作180、中作9及中作59等品种。更多还原

【Abstract】 The evaluation of resistance of germplasm to rice stripe and ricebreeding program were conducted in the infected area for six years.Theresults are as follows:1)Indica rice has better disease resistance than Japanica rice;Theprogenies between Japanica and Indica rice and between lowland and up-land rice are more resistant to the disease than those between Japanicavarieties.2)The Indica rice varieties Tadtkar,Tetep,C4-63,Zhaiyeqing 8,IR26,IR8 as well as some Japanica rice varieties such as Norin mocil39,Chugoku No.31 etc.,have rather strong resistance and can be used asresistant sources for breeding program.3)As greater selective pressure was created by combining natural andartificial selection together,lines with transfered resistant genes can bescreened out so that high-yielding,better resistant Zhongzuo 9,180 and59 varieties were developed.更多还原
