Abstract
本研究利用28個日本型稻品系間之雜交F2和F3植株，用臺灣之第4，第13，第22和第25等稻熱病病原生理小種之孢子懸浮液，使用噴霧法或注射法分別在稻苗第五至第六葉齡時接種，以探究稻對不同稻熱病病原生理小種抵抗性之遺傳。 利用上述四種稻熱病病原生理小種試驗結果，發現稻對此四種不同病原生理小種之抵抗性，大部分受一對顯性抗病因子所支配，同時發現抗病因子Pi4-Pi13, Pi22-Pi25 及Pi4-Pi22間互相獨立。另外發現此四抗病因子與無葉舌因子lg；Pi4與標示因子A, P, Ps1, Ps2, Bf, d2及Pi22與標示因子Ph, Rc等之間亦無連鎖關係。
The present study was conducted to find out genes controlling the resistomses to different blast fungus races occurring in Taiwan. The F2 and F3 hybrids between 28 Japonica rice strians were tested for blast-disease resistance using four different races, 4, 13, 22 and 25. Spore suspension was inoculated with rice seedling at the five-leaf stages by using both spraying and injecting methods. The resistance to the four races were found to be each controlled by a single dominant gene. Experimental data showed that the resistance genes Pi4 and Pi13, Pi4 and Pi22 and Pi22 and Pi25 were independent to each other. Also these 4 genes were not linked with the marker gene lg. Pi4 was independent to the marker genes A, P, Ps1, Ps2, Bf and d2; and so did Pi22 to the Ph and Rc genes involved in the crosses.
