Abstract: Nine accessions of banana germplasm（ No. W1- W9） introduced from the Pomology Research Institute of Guangdong Province were trial planted as treatment from September 2011 to September 2012 in Fushan Town,Chengmai County,Hainan Province,and Musa AAA cavendish cv. Baxi banana was planted as CK. The accessions W1- W6 grew taller than the CK,and Accession W2 grew shorter than the CK. Accessions W7- W9were not significantly different in height from the CK. Accessions W1- W6 had larger leaves than the CK,and Accessions W7- W9 had smaller leaves than the CK. Accessions W1 and W5 had a significantly longer growth cycle than the CK,whereas the other accessions were not significantly different in growth cycle from the CK. Accession W1 had a significantly shorter time for fruit development than the CK,and Accession W9 was not significantly different in fruit development from the CK. The other accessions were significantly longer in fruit development than the CK. Accessions W4 and W7 were significantly larger in fruit cluster than the CK while Accessions W8 and W9 were not significantly different in fruit cluster from the CK,and the other accessions were significantly smaller in fruit cluster than the CK. Accession W6 had a significantly higher number of fruit fingers in the biggest comb than the CK,while Accessions W1 and W3 had a significantly lower number of fruit fingers than the CK,and the other accessions were not significantly different in number of fruit fingers from the CK. Accessions W1 and W2 and W8 were significantly shorter in finger length than the CK,whereas the other accessions were not significantly different in finger length from the CK. Accessions W3,W5,W8 and W9 gave a significantly higher yield per plant than the CK,while Accession W1 yielded significantly lower than the CK,and the other accessions were not significantly different in yield from the CK. Accessions W4,W6,W7 and W9 contained significantly higher soluble sugar in fruit flesh than the CK,and the other accessions were not significantly different in soluble sugar content from the CK. Accessions W6 and W7 had significantly lower acid content in fruit flesh than the CK,while Accession W4 was not significantly different in acid content from the CK,and the other accessions had significantly higher acid content than the CK. Accession W9 had a significantly higher content of Vc in fruit flesh than the CK,while Accession W6 had a significantly lower Vc content than the CK,and the other accessions were not significantly different in Vc content from the CK. Accessions W5 and W8 had a significantly lower edible rate of fruit fingers than the CK,while the other accessions were significantly higher in edible rate than the CK. It is concluded that Accessions W4,W7 and W9 gave better performance than other accessions and the CK and can be used as new cultivars for the banana producing area in the northwest of Hainan Province.
