Aloha Saravanan, I agree with S Benji, all of the breadfruit and relatives will do fine without a taproot. If you donʻt want to graft, then the stem-cutting should be fine, they are grown that way all the time and produce fruit just fine.
One thing I am planning to try though is growing breadfruit and jackfruit from seedlings and letting some of them just become what they will as far as fruit and growth type, and see what we get. Some of the rest will be grafted to varieties to see if having the taproot can increase health, production, drought-resistance, and nutrient uptake from deeper in the ground, since they should develop the taproot. Much like what people are doing in temperate areas with fruit trees, I think the trees grown from seeds will have an advantage in a changing climate. It is just not done often because it is a lot easier to propagate them from cuttings. One thought is that since these species have been propagated asexually for so long, we need new varieties because the climate and conditions in the world are changing so much.
