Abstract

The present investigations were carried out in Fruit Science Department under aegis of All India Coordinated Research Project on Arid Zone Fruits at College of Horticulture and Forestry, Jhalawar on new established orchard during 2010 to evaluate the four different custard apple cultivars collected from different horticultural institutes of the country. The fruit quality characteristics during first bearing (2016) revealed that maximum fruit weight (169.38g), pulp wt. (68.27g), pulp % (40.71) was observed in Balanagar cultivar, however maximum TSS (35.73°brix), higher yield/plant (3.81kg), less no. of seeds (24.80) and less seed weight/ fruit (6.63) was estimated in Raydurg cultivar. The quality attributes of cvs. Balanagar and Raydurg were found at par with each other and were found superior over Ramsita and APK (Ca-1) cultivars during first bearing. The evaluation of custard apple fruit quality during second bearing (2017) revealed that maximum average fruit weight (224.34g), pulp weight (100.03g), pulp % (44.54) and yield/plant (5.60kg) was recorded in Balanagar cultivar, however maximum TSS (32.88obrix), less number of seeds (27.80), less seed weight/fruit (7.35g) was estimated in Balanagar cultivar and were found higher over Ramsita and APK (Ca-1) cultivars. The genetic studies revealed high heritability values for fruit weight (148.79), pulp weight (149.29), pulp percentage (149.05), number of seeds/fruit (148.41), seed weight/fruit (149.87), TSS content (148.41) and fruit yield/plant (147.89) among custard apple cultivars. The present studies determines that Balanagar and Raydurg cultivars have shown promise under heavy black soils of Jhalawar district and holds potential for this crop in subhumid climate having good average annual rainfall (750mm).
