中文摘要 | 為了改進梗稻病害蟲扺抗性,於民國71年第二期作以梗稻台農67號 與秈稻IR4227-18-3-2雜交,在雜交第一代產生部分不稔實,或稔實而稻穎變成 黑色現象,回交梗稻一次以後該種現象即漸次減少。雜交後代二個固定品系具有 豐產及台農67號之米質理化特性,並抗稻熱病及白枯病,此表示梗秈稻回交一 次之雜交後代,秈稻之抗稻熱病及白枯病基因有轉移到梗稻台農67號,並且具 有梗稻台農67號米質理化特性,但食味性稍佳。 |
英文摘要 | In order to improve the pest resistance of japonica rice, a hybridization by crossing japonica (Tainung 67) with indica (IR 4227-18-3-2) was made in the second crop of 1982. Although partial sterility and black husk grains appeared in the F1 generation, the phenomena reduced following the backcrossing with japonica. From the progenies of the cross, two lines with the characters of high yield, similar rive quality as Tainung 67, but resistance to rice blast and bacterial blight were selected. This suggested that in the first backcrossing, the genes of blast and bacterial blight resistance in the indica had been transferred to japonica. On the other hand, the physico-chemical properties of rice in the selected lines were similar to Tainung 67, but the eating quality was better. |
