Variability studies in guava (Psidium guajava L.) genotypes for growth and yield attributes at Chhattisgarh plains

Abstract

Eighteen guava genotypes viz., BSPG-1, BSPG-2, BSPG-3, BSPG-4, BSPG-5, BSPG-6, BSPG-7, BSPG-8, BSPG-9, RJMG-1, RJMG-2, RJMG-3, RJMG-4, RJMG-5, RJMG-6, RJMG-7, RJMG-8 and RJMG-9 were showed wide range of variation with respect to plant growth and yield attributes. The result revealed a great variability for various characters which helped to identify the most promising genotypes. The tree height varied from 3.50–4.43 m, trunk girth varied from 39.25–55.44 cm, North-South spread ranged from 5.11–7.78 m, while East-West spread varied from 5.10-7.84 m. Number of fruits per tree varied from 55–121 and fruit yield per tree varied from 8.16–21.32 kg. fruit length (6.23 to 7.84 cm), fruit width (6.41 to 7.66 cm), fruit weight (130.00 to 229.17 g), pulp weight (112.33 to 205.55 g), seed weight (2.32 to 3.70 g), number of seeds per fruit (177 to 346.67).
