嘉義農業試驗分所59年第二期作以人工接種方法檢定臺中在來1號 × Mudgo 之 F1,F2及F3雜交後裔與IRS × Mudgo之F2植株，以及其親本對褐飛蝨之抵抗性，初步試驗結果，顯示水稻品種Mudgo所具抗蟲性為由一對顯性遺傳因子所控制。
The experiment was conducted at the Chia-yi Agricultural Experiment Station in the second crop of 1970. The reaction of F1, F2 plants and F3 families of T (N) 1 × Mudgo, and the F2 plants of IR8 × Mudgo were evaluated under artifical infestation with brown planthopper nymphs. Mudgo is highly resistant to the brown planthopper whereas IR8 and T (N) 1 are susceptible to this instect.
The results obtained are summarized as follows:
1.The F1 plants of T (N) 1 × Mudgo were as resistant as Mudgo, showing that the resistance to the brown planthopper in Mudgo is completely dominant.
2.The reaction of F2 plants of T (N) 1 × Mudgo and IR8 Mudgo to the brown planthopper agreed satisfactorily to the probability for monogenic inheritance, indicating that the resistance of Mudgo is controlled by one dominant gene.
3.The homozygous resistant, segregating, and homozygous susceptible F3 lines of T (N) 1 × Mudgo were close to an expected ratio of 1:2:1. This results further support the hypothesis that resistance to the brown planthopper in the variety Mudgo is conditioned by a single dominant gene.
