中文摘要 | 本研究以水稻4個雜交組合的F�秧皒s探討對鏈黴素耐性(葉片白化程度) 之遺傳。結果顯示水稻F�秧皒s在對鏈黴素的耐性、苗高、葉長及葉寬均有超越 分離現象;各為部分顯性、超顯性、超顯性、及部分顯性或超顯性基因作用。廣 義遺傳率各為69-73-35-50、34-42及35-54,正反交間無顯著差異。而各耐性程度之 性狀間呈顯著正相關。 |
英文摘要 | In this experiment, varietal variation was used to study genetic behavior in streptomycintolerance (inhibition of chlorophyll formation) of rice. F2 population of rice showed more widevariation in streptomycin tolerance and treated seedling characters than their parents. Thesecharacters were controlled by partial dominance or overdominance, respecitively. Heritabilities ofstreptomycin tolerance, seedling height, leaf length and leaf width were 69-73, 35-50, 34-42and 35-54, respecitively. There were no significant differences between reciprocal crosses inF2 population of rice. Significant positive coirelations were obtained among the four characters. |
