Correlation studies of different physico-morphological characters in citrus rootstock genotypes with fruit yield under Vidarbha region

Abstract

The aim of this study was to find out relationship between yield and yield components of citrus rootstock genotypes and ultimately the development of new genotypes with more yield comprising of important horticultural traits. Thirty genotypes of citrus rootstocks belonging to four species viz., C. jambhiri, C. limonia, C. pseudolimon and C. macrophylla were collected from Akola, Nagpur and Amravati districts and analysed for 43 physico-morphological characters. Correlation study revealed that the correlation of fruit yield with fruit weight (0.587), pomace weight (0.564), fruit volume (0.562), leaf area (0.560), number of fruits tree-1 (0.502), leaf lamina length (0.490) and leaf lamina width (0.468) was highly significant and in positive direction. It was also positively and significantly correlated with stem girth (0.447), petal width (0.451), chlorophyll content (0.423), fruit diameter (0.382) and weight of 20 seeds (0.377), whereas significant and negatively correlated with non-reducing sugars (-0.429) and total sugars (-0.400).
