Abstract
The exploitation of somaclonal variation is an efficient approach to select improved Cavendish-type banana cultivars with superior horticultural traits and resistance to Fusarium wilt, caused by Fusarium oxysporum f. sp. cubense race 4 (Foc race 4) in Chinese Taipei. TC3-1035, an improved somaclonal variant of Tai-Chiao No. 3, was selected and released as a new banana cultivar Tai-Chiao No. 5 in 2007. It inherited the semi-dwarf status and moderate resistance to Foc race 4 of Tai-Chiao No. 3, but not the susceptibility to flower thrips, Thrips hawaiiensis, at shooting stage.
It also has a higher yield potential.
Under suitable field management, plant height of Tai-Chiao No. 5 is 2.7 m, and its fruit size, shape and yield capacity are as good as those of Pei-Chiao, which is the most widely planted Cavendish cultivar in Chinese Taipei.
During the 7-year consecutive evaluation trials, Fusarium wilt incidence in Tai-Chiao No. 5 plants was 5-25% whereas 10-50% plants were affected in Pei-Chiao established in the same infested plot.
This is an indication of the stable resistance of Tai-Chiao No. 5 to Foc race 4. With additional benefit of easy ripening and good eating quality, Tai-Chiao No. 5 is now well accepted, both in the local and Japanese market.
Currently, a total of 0.9 million tissue-culture plantlets, about 450 ha, have been released to banana growers in Chinese Taipei.
