Abstract :

In this research reaction of 10 Khuzetan native date palm cultivars clustered to 4 groups as as Dates with too much contamination including khadravi. Highly contaminated dates including Braim, Berhi, Gantar and Sayer. Dates with average contamination including Ashkar, Zahedi, Chibchab and Raim. Slightly contaminated dates including Dayri. The characters such as bunch number, bunch weight, pedicel length, main stalk of bunch length, smallest stand lenght , stand number and sugar percent have significant correlation with lesser moth injury. Other haven’t significant correlation with lesser moth injury.
