Multilocation Adaptability Studies of Pecannut for Assessing the Scope of Pecanut Cultivation in Punjab

Abstract

Pecans (Carya illinoinensis) belong to Juglandaceae family. It is large tree and may go upto the height of 20-30 meters and sometime upto 40 meters.  The productivity period spread over the span of several hundred years producing nuts of great commercial value. Pecan is enriched source of fatty acid (mono and poly unsaturated) and bioactive substances attributing various health benefits. Several researchers have observed that fruit quality is affected by various Preharvest and postharvest factors. The main problem associated with pecans storage is lipid oxidation which may cause noticeable off-flavor. In the present study a multilocation trial of two varieties of Pecannut “DMA-2 and “DMA-1” were done. DMA-2 selection proved superior in terms of Nut Weight (9 g) and Kernel weight (5 g) as compared to values of Nut weight (5 g) and kernel weight (3 g) in case of DMA-1. In terms of number of nuts per tree DMA-2 selection produced 20 % more nuts per tree than DMA-1.
