There are still no measures to control guava wilt and the growers are losing interest in guava growing and cutting down guava orchards to convert it to lemon and mango orchards. A stable in vitro selection system developed on the basis of the current findings can go a long way in eliminating single trait problem while retaining others and also, shortening the time to release a variety which otherwise would entail a long period of 10-12 years by conventional means.
