Abstract
利用高產但感黃萎病之水稻品種臺南5號和臺農61號為母本或輪迴親，及以抗病品種Firooz-（1）和Kabara為父本或非輪迴親，以譜系法和回交法同時進行抗水稻黃萎病之育種工作，經五年的時間已選出五個抗病品系。此五個抗病品系全部選自以臺農61號為母本或輪迴親的什交組合，其中有YD-15、22、28和75等四個品系之抗病因子來自Kabara，僅有YD-62一個品系之抗病因子來自Firooz-（1）。又五個抗病品系中有YD-62和75等二個品系選自譜系法，其株高及生育日數較選自回交法者為矮及早熟。五個抗病品系之產量在第一期作之表現均較臺南5號高，但第二期作則因褐飛蝨之為害而影響產量至鉅。五個抗黃萎病品系之不具褐飛蝨抵抗性為其最大缺點，但仍可供今後進一步從事抗黃萎病育種的良好種源及橋梁親本之利用。
Yellow dwarf is one of the major diseases of the second crop rice in Taiwan. In order to develop the disease resistant varieties, two susceptible but high yielding varieties, Tainan 5 and Tainung 61,were used as the female(recurrent) parents, and two resistant but tall varieties, Firooz-(1) and Kabara, were used as the male (donor) parents in this study. Selection for the disease resistance were made using both pedigree and backcross methods. Artificial inoculation of pathogens was made using the vector insects, leaf-hopper.
Five selected lines were found to be highly resistant to yellow dwarf disease after testing three times by artificial inoculation. All of them are from the progenies of Tainung 61 which was used as a recurrent parent. Four resistant lines (YD-15, 22, 28, and 75) carry the resistant gene transferred from Kabara, while the remaining line YD-62 carries the resistant gene transferred from Firooz-(l).
Two of the five resistant lines were selected by pedigree method and the other three by backcross method. Lines selected by pedigree method (YD-62 and 75) were found to have shorter plant height and earlies maturity than those selected by backcross method. All resistant lines were found to be higher in grain yield than that of the check variety (Tainan 5) in the first crop, but lower in the second crop due to the severe damage by brown hopper. Five yellow dwarf resistant lines together with other lines are now under further yield trials.
