EVALUATION OF SOME WHEAT VARIETIES AGAINST LEAF BLIGHT (Bipolaris sorokinianai

Abstract

A net house experiment was carried out in the field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to evaluate ten wheat varieties against leaf blight (Bipolaris sorokiniana). The wheat seeds of varieties Sonalika, Kanchan, Barkat, Shatabdi, Aghrani, Pavon-76, Akbar, Gourab, Sourav and Protiva were collected from Banngladesh Agricultural Research Institute (BARl), Gazipur. At ear initiation stage, flowering stage, milking stage and hard dough stage minimum disease severity was recorded in the variety Shatabdi and maximum in the variety Sonalika. The highest number of grains/ear (36.95) and number of healthy grains/ear (36.43) were recorded in the variety Shatabdi The highest 1000-seed weight (43.1Og) were recorded in the variety Gourab and lowest in the variety Protiva. The highest grain yield/pot (5.97g) was recorded in the variety Gourab and lowest yield/pot (4.40g) in the variety Pavon-76. The highest straw yield /pot (14.13g) was recorded in the variety Barkat and lowest (9.IOg) in the variety Shatabdi.
