Abstract

Twenty-one low-chill pear germplasm were evaluated for plant growth, fruit yield and fruit quality parameters at Horticulture Research Centre, Patharchatta, G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, during 2001–02 to 2003–04 for various vegetative, reproductive and yield parameters. The mean performance values for tree height (10.0 m) and trunk girth (56.8 cm) indicated larger values for Pant Pear-18 and LeConte, respectively. The maximum canopy spread (5.1 m) was recorded in Pyrus pashia and Pant Pear18, respectively. Among fruit quality traits maximum fruit weight was recorded in Pant Pear-3 (11.3 g), fruit length in China (8.7 cm), TSS in LeConte (15.2%), acidity in Tumaria (0.37), total sugar in LeConte (9.1%) and fruit yield in Pant Pear-3 (26.5 q/ha) during the study. The variability observed in the pear germplasm can be used for the genetic improvement of fruit yield and quality.
