Abstract

Guava exhibit greater variability on the region-specific which could lead to discovers a significant genotype that are suitable for a particular area or region in terms of yield and quality parameter. The growth, yield and quality traits of 21 genotypes of guava (Psidium guajava L.) were evaluated during the winter season of 2018-19. Plant height was higher in G-12 (8.55 m) whereas, the minimum height was recorded in G-15 (2.50 m). The maximum North-South spread was recorded in genotype G-7 (8.30 m) but East-West spread was recorded in genotype G-2 (6.15 m). In visual observation of canopy shape, it was seen that out of the 21 genotypes, 2 genotypes were found erect type, 7 genotypes were semi spreading, and 12 genotypes were spreading type. There was no variation in bark colour and leaf colour in selected genotypes but number of leaves/30cm shoot and size varied. The result showed that the values of physical parameters viz. fruit length (9.0 cm), fruit width (8.04 cm), pulp percentage (98.35 per cent) and thickness of pulp (1.8 cm) were found maximum in genotype G-13. Thus, genotype G-13 was found superior over other genotypes which may be selected for further evaluation and recommendation.

Conclusion

Based on result, it is noted that G-12 recorded maximum plant height (8.55 m), whereas; the minimum height was recorded in G-15 (2.50 m). The maximum North-South spread was recorded in genotype G-7 (8.30 m) but East-West spread was recorded in genotype G-2 (6.15 m). As far as physical parameters are concerned the maximum fruit length (9.0 cm), fruit width (8.04 cm), pulp percentage (98.35 per cent) and thickness of pulp (1.8 cm) were found in genotype G-13. Thus, genotype G-13 was found superior over other genotypes which may be selected for further evaluation and recommendation. In visual observation of canopy shape, it was seen that out of the 21 genotypes, 2 genotypes were found erect type, 7 genotypes were semi spreading and 12 genotypes were spreading type. The variability in these selected genotypes may be due to genetic makeup and agro-climatic conditions of the locality.
