I. Introduction heat is a staple food crop of majority of the people in the world. However, its production depends on availability of suitable varieties and control of diseases and pests. Plant breeders provide suitable varieties to farmers to boost food production and minimize loss incurred by pests and diseases. With the objective of providing suitable varieties to farmers we evaluated 20-wheat genotypes on 14 parameters including a test for Karnal bunt infestation. This paper presents the findings of this experiment. II. M aterials and M ethods Afield experiment was conducted in Rabi season 2019-20 at Center for Research and Development (CRD) located at Gaunar-Usaraha, Gorakhpur, Uttar Pradesh. The experimental site is located at 26°42' 45.5" N latitude, 83°36'36.6" E longitude and 86 m above mean sea level. The climate is semi- arid with hot summer and cold winter. Nearly 80% of the rainfall is received during monsoon along with a few winter showers. Twenty wheat germplasm, included in this experiment, were taken from the germplasm stock available at CRD and BRD PG College, Deoria. These genotypes were raised in a randomized block design in a timely sown condition with standard package of practices for wheat cultivation. Thus, 20 genotypes were evaluated on 14 parameters in three replications. The parameters evaluated are 1. Biological yield (abbreviated as Bio Yield), 2. 1000 seed weight, 3. Yield per hectare, 4. Days to 50% flowering, 5. Flag leaf area, 6. Karnal bunt infestation, 7. Effective tillers, 8.Spikes/m 2 , 9.Spikelets/ear, 10.Ear length, 11. Peduncle length, 12.Plant height, 13.10 Ear weight and 14.Yield/Plot. Data were collected on five randomly selected plants of all 20 genotypes and were compiled to calculate average of three replications. These were further used to calculate replication mean. These values were subjected to normalized cumulative rank (NCR) analysis as discussed by Singh and co-workers (Sanoj Kumar 2021; Singh 2017; Singh et al. 2018; Yadav et al. 2020). The idea of this analysis is based on the concept of crop ideotype as given by Donald 1968. That is why, in this analysis, we are looking for ideal plant types (=crop ideotypes) that would rank relatively high in majority of the parameters and would come first in cumulative rank or normalized cumulative rank.

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.
