Abstract

Eleven varieties of Sapota (Manilkara achras (Mill) Forb)were evaluated under humid tropical conditions at Central Horticultural Research Station (IIHR), Chettalli (Karnataka) during 2011 and 2012 for growth and yield.Higher plant height was recorded in CO-1 (9.02m) followed by cvs. CO- 2 (8.22 m) and Gutti (8.15m) while it was lowest in cv. in Krithi Bharthi (5.79 m). The scion girth was also highest in cv. CO-1 ( 96.53 cm) while it was lowest (57 cm) in cv. Krithi Bharathi . The plant spread was higher in cvs. Kalipatti and CO-2. The number of fruits were highest in cv. Singapore (1521 fruits) closely followed by cvs. Kalipatti ( 1462 fruits ) and Cricket Ball (1256 fruits)and lowest in CHES selection (232.5 fruits). The fruit weight was highest in CHES selection (158.8g) and lowest fruit weight in cv Singapore (59.3g). The highest yield per tree was recorded in cv. Kalipatti (135.2 kg) closely followed by cv Cricket Ball (133.7 kg). The lowest yield was recorded in cvs. CHES Selection (41.8 kg), PKM-1 (50.5 kg), CO-1(53.71 kg) and CO-2 (62.6 kg). The total soluble Solids were highest in cvs. Kalipatti (20.4° Brix) PKM-1 (20.1520.4° Brix) and DHS-1 (19.2520.4° Brix). The fruit shape index varied from 0.84 in cv. CO-1 to 1.28 in cv. Singapore. The titrable acidity and ascorbic acid was found low in all the varieties. The result concludes that cvs. Kalipatti and Cricket Ball were found best in terms of yield and quality of fruits.
