A new banana line ＂W-07＂ with uniform fingers and shorter growing period was selected from the in vitro propagated progenies of banana line ＂8818＂ . The main morphological characteristics of the ＂W-07＂ include medium-short stalk （231 cm in height）, moderate pseudostem thickness （70.2 cm in diameter）, fast vegetative growth, and dark green elliptical leaves with leaf length to width ratio of 2.05. The ＂W-07＂ yielded high： bunches 80.6 cm long, 24.42 kg/bunch; hands 6-8 hands/bunch, 4.0 kg/hand; fingers 130.2 fingers/bunch, 20.3 cm in length and 180 g/finger. The whole growth stage for the line ＂W-07＂ planting in spring is 317 days, and this line is hence suitable for planting in Hainan Island.
