ABSTRACT
Ber is a quick growing and early bearing fruit which yields a heavy crop every year and perhaps requires the least inputs and care. In spite of that heavy fruit drop after setting, small fruit size and poor fruit quality in many commercial cultivars is a common phenomenon in many ber growing areas in the country. Earlier ber was propagated by seeds during earlier period. But the main disadvantage of this method is of heterozygosity and variability in seedling progeny. Presently, a superior variety of ber is propagated by budding on seedling rootstock. In order to overcome embryo abortion Wang used male sterile germplasm as female parent in cross breeding of Chinese jujube. Ber trees can withstand extremely high summer temperatures and are found to grow well in regions having maximum temperatures of 39 to 42° C and can tolerate temperatures as high as 49-50° C.
