  • Banana（ Musa acuminata L. AAA group,‘Brazilian’） calli and buds induced from immature male flowers were used as explants,radiated with 60Co-γ ray for mutagenesis and then screened by low temperature selection. Banana plants of two cold tolerant lines（ Kanghan 9 and Kanghan 11） and the control without radiation treatment were determined in terms of starch,total sugar,glucose,fructose and sucrose. The two cold-tolerant banana lines contained highly significantly higher total sugar,sucrose,fructose and glucose in the banana fruit than the control（ P ＜0. 01） and also had higher content of total starch,amylose and amylopectin in the fruit than the control. However,Kanghan 11 had a lower amylose/amylopectin ratio in the fruit than the control.

Abstract: Banana（ Musa acuminata L. AAA group,‘Brazilian’） calli and buds induced from immature male flowers were used as explants,radiated with 60Co-γ ray for mutagenesis and then screened by low temperature selection. Banana plants of two cold tolerant lines（ Kanghan 9 and Kanghan 11） and the control without radiation treatment were determined in terms of starch,total sugar,glucose,fructose and sucrose. The two cold-tolerant banana lines contained highly significantly higher total sugar,sucrose,fructose and glucose in the banana fruit than the control（ P ＜0. 01） and also had higher content of total starch,amylose and amylopectin in the fruit than the control. However,Kanghan 11 had a lower amylose/amylopectin ratio in the fruit than the control.
