Genetic diversity of jujube (Ziziphus mauritiana) cultivars
2018
The present study was conducted on five jujube (Ziziphus mauritiana Lamk.)
cultivars (Anokhi, Karela, Dill bahar, Ajooba and Dehli white) grown in two
locations in Punjab, Pakistan during seasons 2014-2015 and 2015-2016. The
aim of the study was to determine genetic diversity based on fruit
properties fruit (weight, length, diameter), seed (weight, length,
diameter), pulp weight, juice pH, total soluble solids (TSS), titratable
acidity (TA), vitamin C, sugars (total, reducing, and non-reducing),
antioxidant capacity and total phenolics. All cultivars significantly
differed from each other in their fruit physico-chemical attributes. Dehli
white cultivar had the highest fruit weight (22.90 g), fruit diameter (37.58
mm), pulp weight (16.83 g) and seed diameter (10.33 mm) than other
cultivars. Dill bahar had the highest fruit length (43.75 mm), seed weight
(2.69 g), juice pH (4.98), vitamin C content (55.86 mg/100 mL juice) and
total phenolic contents (146.98 渭g GAE per mL). Anokhi had the highest seed
length (26.13 mm), non-reducing sugars (37.81%), total sugars (47.23%) and
antioxidant capacity (1016.8 mM trolox per 100 mL). In Bahawalpur and
Faisalabad鈥檚 environmental conditions Dehli white and Dill bahar cultivars
were with better physical properties. However, according to biochemical
properties Ajooba and Anokhi cultivars were better in Bahawalpur.
