“…In the present study the phenotypic and genotypic coefficient of variation was found to be high for gluten content % and grain yield per plant. Similar observation was also reported by Kalimullah et al, [6] Ranjana et al, [7] Dutamo et al, [8] Arya et al, [9] Kumar et al, [2] and Prasad et al, [10]. Moderate GCV and PCV were observed in biological yield per plant, harvest index, number of productive tillers per plant.…”

The present experiment was carried out during Rabi 2021-2022 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut-250110 (U.P.). The material used in the present study comprised 103 germplasm accessions of Wheat (Triticum aestivum L.) having variability for various agronomic and morphological characters were obtained from the available germplasm in the Department of Genetics & Plant Breeding, SVPUA&T, Meerut. The number of genotypes are 103 including four check (DBW-71, DBW-222, DBW-173, HD-3226), the Plot size is10 row 2.5m length spaced at 0.25m and the date of sowing is 20 December, 2021 on Augmented experimental design. Twelve observations were recorded. In each plot, five plants from each genotype were arbitrarily selected and tagged to record the observations studied characteristics except days to 50 % flowering and days to maturity they were recorded on plot basis. The highest value of biological yield per plant was estimated in CSW-18 (45.16g), DBW-621 (51.45%) recorded a high value of harvest index and the maximum grain yield is from CSW-18 (15.94) g. High heritability coupled with high genetic advance observed for gluten content, grain yield per plant, biological yield per plant, harvest index and number of productive tillers per plant.

“…High genotypic and phenotypic coefficient of variation was observed for number of spikes/plant (30.23 & 32.42) followed by number of effective tillers/plant (29.45 & 29.87) in EIII, High genotypic and phenotypic coefficient of variation was observed for number of effective tillers/plant (27.2 & 27.83) followed by number of spikes/plant (25.75 & 27.39) in pooled analysis. Similar results reported by Mundiyara et al [8], Tiwari et al [9], Rajput [10], Biru and Negash [3], Choudhary et al [4], Prasad et al[5] and Sharma et al[7] and Chaudhary et al[6]. This result indicated that there was negligible variation in all different environmental conditions means these traits were show genotypic variation they would be used in hybridization programme for better crop improvement.…”

Present study was carried out to evaluate genetic variability and inheritance of yield contributing traits using fifteen cytoplasmic male sterility (CMS) based F1 hybrid of wheat involving fifteen CMS based lines and one restorer line received from IIWBR, Karnal and Division of Genetics, IARI under CRP on hybrid wheat programme along with five wheat checks. Experiment was conducted during Rabi 2019-20 in randomized block design with two replications in three different sowing dates at Seed Breeding Farm, JNKVV, Jabalpur. Analysis of variance revealed that, significant differences among the crosses for all the traits indicated that the presence of sufficient amount of genetic variability. High GCV% and PCV % accounted for the traits number of effective tillers/plant and number of spikes/plant, thousand grain weights, spike weight and grain yield/plant in EI, EII, EIII and pooled environment. Genetic advance as percentage of mean estimate was highest for biological yield/plant (33.99%) and mean noted respectively number of effective tillers/plant, thousand grain weight, number of spikes/plant and grain yield/plant in different environment conditions. Hence, selection of these traits would be effective for further crop improvement programme. On the basis of mean and range, maximum mean value noted in respective CMS based hybrids viz., grain yield/plant (CMS96A*Res-37), thousand grain weights and grains/ear (CMS86A*Res-37), harvest index (CMS85A*Res-37), number of effective tillers/plant (CMS95A*Res-37). These crosses contributed directly for yield improvement and to meet the demand of increasing population to make India self sufficient in food security.

“…High genetic gain was observed for grain yield per plant followed by biological yield per plant, number of productive tiller per plant, spike length and weight of grain per spike. Moderate genetic advance was recorded for number of spikelets per spike followed by number of grains per spike, plant height, chlorophyll content, harvest index and protein content and low for days to heading followed by days to maturity and 1000 grain weight" [32,33].…”

Ten bread wheat genotype and their all possible cross combinations excluding their reciprocals (10 parents+45 F1s+45 F2s) were evaluated in a randomized block design with three replications during Rabi2022-2023 at Student’s Instructional Farm, C. S. Azad University of Agriculture and Technology-208002, Kanpur, U.P to get the extent of variability and related parameters to select effectively for grain yield and quality character. It is the big challenge for researchers to get high grain yield with high protein. The data was recorded on fourteen characters viz., days to heading (50%), days to maturity, plant height (cm), number of productive tillers per plant, chlorophyll content, spike length (cm), number of spikelets per spike, number of grains per spike, weight of grain per spike (g), 1000 grain weight (g), biological yield (g), harvest index (%),protein content (%) and grain yield per plant (g). The variability among parents was highest for days to maturity it ranged from 117.33 to 137.67 with the mean value 126.60. The variation in F1 progenies was highest for plant height ranged from 85.97 to 120.53 with the mean value of 96.71.The variation in F2 progenies was highest for plant height ranged from 83.70 to 120.20 with the mean value of 94.99. The result showed higher estimated values for phenotypic coefficient of variability(PCV) of all the fourteen characters as compared to their corresponding genotypic coefficient of variability (GCV). Highest value of PCV and GCV were noted for grain yield per plantin both generation F1s and F2s except GCV were observed for none of the character F1s. high heritability estimates were recorded for all characters in both generation F1s and F2s.High genetic gain was observed for grain yield per plant followed by biological yield per plant in both generation F1s and F2s.
