中文摘要 | 本試驗利用由回交育種法育成之抗�蚽f菜豆新品系台中系1號、2號、 11號、12號、15號等進行品系比較試驗,以輪迴親黑仁衣竺為對照品種,以選 育優良抗�蚽f菜豆新品系藉以推廣栽培。試驗結果如下: 1.參試各抗�蚽f品系始收日數,終收日數、莢形、莢色等主要園藝性狀皆達到與 輪迴親近似或更優良的程度。其中台中系11號比對照品種增產26.7∼32.6%,台 中系12號亦比輪迴親略增,其嫩莢長圓而直,頗具市場競爭潛力。 2.參試各品系不同期作間�蚽f罹病度皆低於對照品種,於春作台中系11號、12 號之�蚽f罹病度各為1%,而對照品種為19.5%;秋作對照品種�蚽f罹病度為 87.8%,而台中系11號、台中系12號,罹病度分別為10.3%與5.0%,顯示有優 越之�蚽f抗病性,已達育種目標。 |
英文摘要 | A comparison test was conducted in two different crop seasons for the newly bred lines of common bean, Taichung 1, 2, 11, 12 and 15 obtained from a backcross breeding. The check variety was the recurrent parent cv. Black creasback. The results are summarized as follows: 1.All the tested lines performed the same or better than the check variety in terms of days to first harvest, last harvest, pod shape, and pod color. Taichung 11 yielded the highest in both crop seasons, being respectively 26.7% and 32.6% higher than that of the check. Taichung 12 yielded slightly higher than its recurrent parent. Owing to its long, round and straight pods, this line showed a good marketing potential. 2.All the tested lines had less rust infection rate than the control variety in both crop seasons. In the spring crop, the infection rate in Taichung 11 and Taichung 12 was 1% as compared to the 19.5% found in the check. The coresponding values for the fall crop were 10.3%, 5% and 87.8% respectively. It is, therefore, indicated that Taichung 11 and Taichung 12 obtain high rust resistant ability. |
