| This study was conducted during three successive seasons of 2013 up to 2015 on Sadat pear (selected clone from (Le-Conte) pear (Pyrus communise, Rehd). Trees grafted on Pyrus betulaefolia [P. betulifolia] rootstock and grown in sandy soil at private orchard in Sadat city, Menofya Governorate, Egypt, to evaluated parameters [(date of: vegetative bud break, flower bud break, full bloom and petal fall, vegetative growth parameters (No. of leaves per shoot, shoot length and leaf area), fruiting (fruit set, maturity and yield) and fruit quality (physical and chemical analysis)] at harvest or cold storage at 5±1 ºC and 90% relative humidity for 60 days.The results showed that, bud break time was late at first week of April, and maturated at the end of September compare to 15/8 for "Le-Conte" and fruitful with a consistent bearing of regular shape, large size fruits (385g) and produced higher yield per tree 123.4 kg (average of three seasons) Sadat pear trees yield late fruits and has good keeping quality during cold storage so, it offer fresh fruits for long period in markets, where as was known that the most production of pear fruits persists just through two months.With respect to molecular genetic studies, the data obtained from RAPD-PCR showed nine bands as total bands with molecular weight ranging from 180-1100bp. On the other hand, ISSR-PCR analysis generated ten bands with molecular weight ranging from 120-1360bp. | ||
