Abstract
The present investigstion entitled “Collection and Evaluation of Custard apple (Annona squamosa L.) genotypes in Chhattisgarh plains” was carried out in the Department of Fruit science, College of Agriculture, IGKV, Raipur through the survey conducted in the different villages of district Bilaspur and Mahasamund, during the year 2016-17. All 18 genotypes were evaluated for growth and yield parameters and physico-chemical aspects. The results revealed a great variability for various characters which helped to identify the most promising genotypes. The tree height varied from 3.22–3.98 m, trunk girth varied from 38.36–42.38 cm, North-South spread ranged from 2.24–3.52 m, while East-West spread varied from 2.11-3.32 m and leaf length as well as leaf breadth varied from 9.13-18.29 cm and 4.55-7.54 cm, respectively. Number of fruits per tree varied from 26–41 and fruit yield per tree varied from 4.05–14.99 kg.
There was variation for physical characters of fruit in genotypes. The fruits physical characters viz., fruit length (7.53 to 11.76 cm), fruit breadth (7.14 to 10.98 cm), fruit weight (155.86 to 365.78 g), pericarp weight (75.85 to 162.58 g), pulp weight (60.44 to 180.56 g) number of seeds per fruit (48.33 to 20.00) and seed weight (15.00 to 23.00 g), also the shape of fruit observed was either round, oval or heart shape. All these physical characters showed significant variation.
The variation was also observed for fruit chemical characters viz., TSS (20.19 to 25.22 0B), acidity (0.32 to 0.45 %), Ascorbic acid (32.4 to 37.8 mg/100 g pulp), Total sugar (13.01 to 18.20%), reducing sugar (10.80 to 14.50%) and non-reducing sugar (2.10 to 3.70%).
The fruit colour observed was dark-green to whitish-green. Seed colour observed was black to brownish-black. The pulp colour was dull-white to creamy-white. The white colour was predominant and was recorded in eleven genotypes. The taste of fruit pulp varied from less sweet to very sweet. The pulp was found as soft or granular.
On the basis of performance of individual genotype, BSPCA-1, BSPCA- 4, BSPCA-8, MSCA-1 and MSCA-5 was located as promising genotypes. All the five promising genotypes were superior in fruit quality traits and could be commercially viable cultivars.
