Evaluation of sunflower germplasm lines against whitefly, Bemisia tabci (Genn.) (Hemiptera: Aleyrodidae) under field condition

Abstract

An experiment was conducted on evaluation of sunflower germplasm lines against whitefly, Bemisia tabaci (Genn.) at college of agriculture Raichur, Karnataka during rabi 2016-17. The objective of the study was to find out the promising sunflower germplasm lines against whitefly under field condition. Among 150 sunflower germplasm lines evaluated for their reaction against whitefly, the germplasm lines viz., PM-4, PM-18, PM-19, PM-26, PM-30, PM37, PM- 39, PM-42, PM-43, PM-52, PM-67, PM-69, PM-73, PM-97 and 85 other germplasm lines were found to be promising against whitefly (category-I). Similarly, PM-6, PM-11, PM-12, PM-13, PM-62, PM-83, PM-87, PM-94, PM-103, PM-107, PM-112, PM-117, PM-121, PM-123, PM-128 and 27 other germplasm lines were grouped as category-II. Further, seven germplasm lines viz., PM-3, PM-78, PM-91, PM-78-1, PM-91-1, PM-92 and PM-155 were grouped under category-III.
