Performance of aonla cultivars under humid tropical conditions of Western ghats

Seven cultivars of aonla (Emblica officinalis Gaertn) were evaluated under humid tropical conditions at Central Horticultural Research Station(IIHR), Chettalli (Karnataka) for 3 years during 2010 to 2012 for growth and yield. Highest plant height (6.32 m), rootstock circumference (75.10 cm), scion circumference (74.24 cm) and plant spread(N-S) (6.18m) was recorded in cv. BSR-1 followed by cv. Kanchan. The highest number of fruits (798) was recorded in cv. Chakaiya followed by cv. Krishna (649), while fruit yield was highest in cv. Chakaiya (26.78 kg/plant) and cv. Krishna (26.34 kg). Highest fruit weight (40.57 g) was recorded in cv. Krishna followed by NA-6(37.72 g). The lowest fruit weight was recorded in BSR-1 (18.59g).The pulp percent was highest in cv. NA-7 (95.50%) and cv. Chakaiya (95.33%). T.S.S was highest in cv. BSR-1(11.5O Brix) followed by cv. Kanchan (9.87oBrix). Ascorbic acid, acidity and sugar percent was higher in cv. BSR-1 than other cultivars. The cv. BSR-1 was found better for growth and fruit quality parameters while yield and fruit size was higher in cvs. Chakaiya and Krishna.
