The inheritance of the marked differences between rice varieties in response to phenyl mercuric acetate (PMA) dust was investigated in the first crop of 1966 at the Chiayi Agricultural Experiment Stations. The resistant japonica-type variety, Chianung 242, was crossed with a sensitive indica variety, Taichung Native 1, and their F1, F2, BC1, and BC2 plants were used in the testing. The individual seedlings or plants were classified for resistance to PMA toxicity based on an arbitrary scale devised by the authors. The observed data agreed with the hypothesis that sensitivity to PMA toxicity is controlled by at least two pairs of alleles, Prna1 and Prna2. The possible implication of tolerance to PMA toxicity on the future rice breeding program is also discussed.
本試驗以分析水稻品種抗有機汞殺菌劑藥害之遺傳現象為目的。供試材料為抗藥害品種嘉農 242 號與感受品種臺中在來 1 號，其 Fl，F2，BCl，及 BC2。分別在溫室及田間噴施西樂生石灰，並按各個體藥害之輕重分級歸類，由此分析結果得知，水稻抗有機汞殺菌劑藥害之性狀，至少受兩對遣傳因子Pma1 與 Pma2所支配。
