Abstract
為研究水稻品種BJ 1等對白葉枯病抗病性之遺傳行為，利用感品種臺中在來號與高雄秈2號分別與BJ 1等抗病品種雜交，並於雜交後裔與親本在孕穗期間進行病原菌人工接種，接種20天調查其發病程度。試驗結果，BJ 1與TKM 6品種為親本所得F1、F2及F3雜種裔之反應，顯示水稻種品BJ 1具有抗病性，係受一對隱性因子控制；而控制TKM6之抗病性則對顯性因子，為後者與IRRI試驗結果一致。
The objective of this study was to investigate the mode of inheritance of resistance to bacterial leaf blight in rice variety BJ 1 (TKM 6 used as a check). The experiment was conducted at Taiwan Agricultural Research Institute in 1973. Two susceptible varieties Taichung Native 1 and Kaoshiung sen 2 were crossed with BJ 1 and TKM 6. The clipping method of inoculating the flag leaves was used for the test of bacterial leaf blight. Reaction was scored 20 days after inoculation on a scale of 0-9 based on the extent to which the lesion spread downward from the cut of inoculation. A score of 0 indicated the most resistant reaction, and 9, the most susceptible.
Results from the genetic study of parental varieties, F1, F2 populations and F3 families of various cross combinations were given in Figs. 1 and 2 and Table 1. The reaction of the hybrid fitted the hypothesis that resistance to the bacterial leaf blight in rice variety BJ 1 was conditioned by a single recessive gene while that TKM 6 was controlled by a single dominant gene.
