Scrutiny of Strategies in developing Parthenocarpic Tomato (Solanum lycopersicum)

Nancy D

Abstract :

Fruit development occurs after victorious completion of early development following pollination, fertilization and maturation. At the end of early development; a green fruit is obtained, which has the size of a mature fruit and the maturation phase commences. Parthenocarpy is the growth of the ovary into a seedless fruit in the dearth of pollination and/ or fertilization. Nevertheless, the current agricultural practices to achieve seedlessness have in–built disadvantages. A considerable difference in dry matter content, sugar and soluble solids were observed in parthenocarpic fruits. The successfully available seedless tomatoes are “Montfavet 191” (pat mutant) developed by mutation in two recessive genes in US market, sha and patI “Sweet”. World’s first seedless tomato, “CV MicroTom” by regulation of genes for auxin synthesis (iaaM) or responsiveness (rolB) driven by DefH9 or the Inner No Outer (INO) promoter from A. thaliana and “Monalbo / porphyre” (single pat– 2 gene mutant). Beyond the seedless nature, these fruits are sweet with firm gel and juiciness. This review has been focused on different strategies available to develop parthenocarpic tomatoes that includes; environmental factors controlling fruit set, gene modifications and terminator technology, which provides an in–depth view towards magnitude of seedlessness.
