Abstract
黑腐病是國際上重要的十字花科細菌病害，由Xanthomonas campestris pv.campestris所引起的黑腐病有11個生理小種，其中以生理小種1 與4 最為重要。本研究以12 個芥藍雜交品系進行抗十字花科黑腐病之苗期篩選，並選出2 個可兼耐黑腐病生理小種1 與4 之芥藍雜交品系。芥F 自交系在抗黑腐病組合力評估，呈現較佳的一般組合力。選獲優良之自交系，可供後續芥藍抗黑腐病雜交親本之利用。9 個芥藍雜交組合成株田間黑腐病自然發病試驗，在二個地區黑腐病罹病度均在30 %以下，其中以編號21-522與21-524表現較好，田間黑腐病罹病度均在10 %以下，成株田間自然發病與苗期人工接種試驗結果一致。選獲優良耐黑腐病之雜交組合，具有優良園藝性狀及產量高的特性，可進一步推廣利用。
Black rot is an internationally important cruciferous bacterial disease. There are eleven physiological races in published reports, among which races 1 and 4 are the most important. The twelve hybrid lines of Chinese kale had been inoculate with Xanthomonas campestris pv. campestris race 1 and 4 on seedling stage. Two Chinese kale hybrid lines had been selected with tolerant of black rot race 1 and 4. The Chinese kale inbred line F showed better general combing ability (GCA) on resistant black rot. Excellent inbred lines have been selected, which can be used as hybrid parents of Chinese kale for resistance to black rot. Nine Chinese kale hybrids lines were tested on the natural incidence of black rot in the field, and the disease index of black rot was below 30 %. Hybrid lines of 21-522 and 21-524 performed better. The disease index of black rot was below 10 %, and the test results of the adult plant and seedling stage were consistent. Excellent horticultural traits and high yield characteristics combination with excellent resistance to black rot were selected, which could be utilized in the further.
