Relative Performance and Karnal Bunt Infestation of Wheat ( Triticum Aestivum L. Em. Thell.) Accessions in Eastern Uttar Pradesh Rajesh Kumar α , Shri Niwas Singh σ , Sanoj Kumar ρ & Baij Nath Singh Ѡ 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). High performers and least bunt infested accessions like BHU-25, HPST-16-17-16, HPAN-101, HPAN-57 and PBW-677 could be further investigated or directly recommended for cultivation in this area.

However its production is limited by non- availability of suitable varieties and infestation of diseases and pests. Therefore, plant breeders’ duty is to provide suitable varieties to farmers so that food production and food security can be insured. With these facts in mind, we evaluated 20-wheat accessions on 11 parameters including a test for Karnal bunt infestation. The present paper reports the findings of this experiment. II. M aterials and M ethods The experiment was conducted in Rabi season 2019-20 at Center for Research and Development 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 and 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. HD2967 was used as a standard check variety. These accessions 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 11 parameters in three replications. The parameters evaluated are 1. 1000 seed weight or test weight, 2. 10 spikes’ weight, 3. yield per plot, 4. spikes per square meter, 5. effective tillers, 6. Plant height, 7.yield per hectare, 8. biological yield per plant, 9.days to 50% flowering, 10. flag leaf area and 11. Karnal bunt infestation. Data collected on five randomly selected plants of all 20 genotypes were compiled to calculate means in 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 in many papers (Sanoj Kumar 2021; Singh 2017; Singh et al. 2018; Yadav et al. 2020). The idea of this analysis came from 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 well or first in all parameters. III.
