Triploid banana breeding could be achieved by crossing tetraploid to improved diploid
banana genotypes. The availability of tetraploid bananas is naturally very limited. One of
methods to produce tetraploid bananas is inducing tetraploid plants using chemicals that
inhibit spindle fiber formation during mitosis such as oryzalin or colchicines. The present
study selects and characterizes autotetraploid Mas Jambe Banana (Musa, AAAA) induced
by in vitro oryzalin treatment that will be used as 2n gamete donors in crosses with improved …
