Abstract:

Custard Apple is one such arid fruit crop grown across various parts of Southern India serves as the fruit of poor man. Custard apple cv. Arka Sahan is an improved hybrid obtained out of Island Gem (Annona atemoya Hort.) x Mammoth (Annona squamosa L.). The present study was under taken mainly to enhance the fruit characters by subjecting it to assisted pollination and various combinations of Gibberellic acid. Among the treatments the combination of GA3 1000 ppm + assisted pollination recorded maximum increment in reproductive parameters such as fruit set (98.23 %), fruit retention (98.16 %) and Time taken for maturity (133.33 days). The fruit characters like fruit weight (409.13 g), fruit length (8.95 cm), fruit width (8.71 cm), pedicel length (6.59 cm), pedicel weight (3.32 g), pulp weight (307.90 g) and peel weight (66.78 g) were also had significant results from the same treatment combination. So it is GA3 1000 ppm + assisted pollination combination proved to be the best treatment for enhancing the reproductive traits.
