FRUIT CHARACTERIZATION OF PAKISTANI DATES
GHULAM SARWAR MARKHAND1*, ADEL A. ABUL-SOAD2, AMEER AHMED MIRBAHAR1,3 AND NISAR AHMED KANHAR4
Abstract: Fruit of 85 varieties of
Pakistani dates were collected throughout the harvest season.
Appropriate Performa was designed to write the scientific and commonly
used properties. These properties included fruit color at Khalal stage,
shape, size (length & diameter), color & height of perianth, fruit group
(soft, semi-dry, dry), edible stage and the micropyle position and split
(wide, narrow, deep). Furthermore, pictures of the whole fruit,
longitudinal and transverse sections and dorsal & ventral sides of seed
have been taken. This study aimed to evaluate the quality of different
Pakistani dates. Aseel variety is considered as one of the predominant
and commercial varieties in Pakistan. It is elliptical in shape like
most of the Pakistani dates. A few of the evaluated varieties have good
properties. The majority of Pakistani dates fall in the semi-dry group.
Most of the varieties, if not all are sensitive to monsoon rains, which
synchronizes with ripening/harvest season. The harvest season of dates
in Khairpur, Pakistan starts from the end of June until the mid of
August. Urgent and rapid demand is being required for the high quality
varieties. Whether, this demand can be achieved by means of
micropropagation of offshoots of these evaluated and selectable
varieties by the tissue culture or to import offshoots of best quality
dates from abroad for propagation needs. 1Date Palm Research Institute, Shah Abdul Latif University, Khairpur, Sindh, Pakistan. 2Horticulture Research Institute, Agriculture Research Center, Egypt 3Plant Tissue Culture and Biotechnology Section, H.
