Morphological and horticultural diversity of plum varieties evaluated under Kashmir conditions

Abstract

This study was carried out to evaluate the morphological and horticultural diversity among 15 plum varieties grafted on seedling rootstocks at ICAR- Central Institute for Temperate Horticulture, Srinagar, Jammu and Kashmir during 2013 and 2014. The highest Trunk cross sectional area (177.37 cm2) was recorded in Santa Rosa and canopy volume (25.42 m3) in Au-Rosa. The maximum fruit yield (57.91 kg tree-1) was recorded in Meriposa and productivity efficiency (0.785 kg cm-2) was in Au-cherry. Highest fruit and pulp weight (58.59 g and 56.49 g) was recorded in Grand Duke and lowest seed weight (0.74 g) in Monarch. The highest length and width ratio (1.42) was recorded in Grand Duke and lowest (0.94) in Black Amber. The fruit quality attributes such as TSS (21.10oB) was estimated in Santa Rosa and acidity (0.69%) was in Au-cherry and Red Beauty cultivars. The varieties Au-Cherry, Meriposa, Tarkol, Beauty and Monark performed better in respect to yield and Grand Duke, Santa Rosa and Methley were better for fruit quality of plum under Kashmir conditions.
