The trait of self-fertility turned a bonus, and domestic cultivars of tomato have been selected to maximize this trait. In the wild, original state, tomatoes required cross-pollination; they had been rather more self-incompatible than home cultivars. As a floral system to cut back selfing, the pistil of wild tomatoes extends farther out of the flower than at present’s cultivars. Tomatoes serve, or are served by, a big variety of companion crops. Although not a illness as such, irregular provides of water may cause growing or ripening fruit to split.
