Multi-Criteria Selection and Screening for Karnal Bunt Resistance of Wheat (Triticumaestivum L. Em. Thell.) in Eastern Uttar Pradesh
Twenty wheat germplasm were evaluated on 14 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 objective of the experiment was to select top five good performing genotypes on the basis of all the parameters and extent of Karnal bunt (KB) infestation. Normalized cumulative ranks were used to assess the relative performance of twenty genotypes. KOH seed soaking technique was used to assess the extent of Karnal bunt infestation. Based on normalized accumulating ranks the performance order of twenty wheat genotypes isHD3117, HPYT480, HPAW152, HD3271, HPAN196, HPYT443, HPAN165, HD3226, HPYT409, HPAN153, HPYT474, CSW18, HPYT424, HPYT489, HPYT441, HPYT490, HPYT426, HPYT418, HPAN163 and HPYT446. Four genotypes were completely resistant. Sixteen genotypes were susceptible to Karnal bunt and infestation ranged from 1.33% (HPYT-418) to 30% (HPYT-446). High performer genotypes like HD3117, HPYT480, HPAW152, HD3271, HPAN196 and Karnal bunt resistant genotypes like HPYT409, HPAN153, HPYT489 and HPYT 490 should be recommended for cultivation in this area.
