Studies on genetic diversity in pummelo (Citrus grandis Merrill) genotypes on the basis of morphological and physiochemical characters

Author(s): AK Baswal, HS Rattanpal, Gurteg Singh Uppal and KS Gill
Abstract: Assessment of genetic diversity in the available germplasm is the prerequisite for the development of improved genotypes through planned breeding programmes. In view of this, ten pummelo (Citrus grandis Merrill) genotypes maintained at College Orchard and Fruit Research Farm of Punjab Agricultural University, Ludhiana were evaluated for vegetative, floral, fruit and seed characters on the basis of IPGRI descriptor for citrus during 2013 to 2015. Morpho-physiological data was subjected to cluster analysis and the tested genotypes were grouped into four clusters, indicating that the genotypes in these clusters have dissimilarity for morphological features and performance. Cluster I was recorded with no fruiting, while cluster III had the highest mean value for fruit weight (1218.17 g), fruit diameter (175.93 mm), fruit length (151.36 mm), fruit rind thickness (21.86 mm) and number of segments per fruit (15.50) and least mean value for total soluble solids (7.720 brix) and 20 seeds weight (5.86 g). Cluster II was characterized by maximum value for titrable acidity (0.89%), 20 seeds weight (6.44 g), seed width (8.47 mm) and least mean value for fruit diameter (134.05 mm), fruit rind thickness (15.55 mm) and seed number (84.5).
