Relative Performance and Karnal Bunt Infestation of Wheat (Triticum Aestivum L. Em. Thell.) Accessions in Eastern Uttar Pradesh.

Abstract

Twenty wheat accessions were evaluated on 11 parameters in an experiment at Center for Research and Development (CRD), Gaunar, Usaraha, Gorakhpur, U. P. in a randomized block design with three replications. The objectives of the experiment were to assess the relative performance of the accessions on various parameters and extent of Karnal bunt (KB) infestation. Normalized cumulative ranks were used to assess the relative performance of accessions. KOH seed soaking technique was used to assess the extent of Karnal bunt infestation. Based on normalized accumulating ranks the performance order of wheat accessions is BHU-25, HPST-16-17-16, HPAN-101,HPAN-57, PBW-677, CRD Gehu 1, BHU-31, ANKUR, HPST-16-17-07, HPAN-111, HPAN-127, HPAN-65, HPST-16-17-15, PBW-Zn 1, HPAN-42, HPAN-164, HD-2967, WB-02, ZINCOL and HPAN-147. All the 20 accessions of wheat were susceptible to Karnal bunt and infestation ranged from 3.67% (HPST-16-17-15) to 70.33% (HPAN-147).
