  • Abstract : Fusarium wilt of banana, caused by Fusarium oxysporum f. sp. cubense (Foc) race 4, is the major constraint for cultivation of banana in Taiwan. For obtaining a resistant variety to replace the susceptible Cavendish, Taiwan Banana Research Institute (TBRI) initiated an innovative breeding program based on somaclonal variation approach. This breeding program, which began in 1984, already produced a total of 13 resistant/tolerant clones; and derived from the wilt-susceptible variety 'Giant Cavendish'. To solve the fusarium wilt problem, three of them were released as the new varieties, 'Tai-Chiao no.1' in 1992, 'Tai-Chiao no.3' in 2001 and 'Formosana' in 2002, for commercial production. The former two varieties are mediocre in resistance to fusarium wilt and in productivity, and moderate success has been obtained. 'Formosana' net only showed a high level of resistance to fusarium wilt just also produced a bunch about 40 percent heavier than that of its progenitor 'Giant Cavendish', a breakthrough in banana breeding. This new variety was released for commercial planting beginning January 2002 to replace both 'Tai-Chiao no.1' and 'Tai-Chiao no.3'. With its superb agronomic and horticultural characteristics, it is believed that Formosana will soen become the major banana variety grown in Taiwan. The novel breeding strategy based on somaclonal variation has proved to be a useful method for the improvement of banana. (Author's abstract).
