1BL/1RS translocation is widely used around the world to enhance wheat yield potential, resistance to various diseases, and adaptation. However, the translocation is combined with inherent quality problems associated with reduced dough strength and dough stickiness due to the presence of Sec-1 on proximal end and absence of GluB3/GliB1 on distal end. Two NILs, one carrying the distal (1RSRW) and the other carrying the proximal (1RSWR) fragment from 1BS, in background of Pavon were used for transferring these two loci in yellow rust resistant version of two elite wheat varieties PBW550+Yr5 and DBW17+Yr5. Foreground and background marker assisted selection was done for the Sec-1- and GluB3+ alongwith Lr26/Yr9/Sr31, Pm8 and 1RS loci in the advancing generation. BC2F5:6 NILs with absence of Secalin and presence of GluB3/GliB1 loci were evaluated for two years in replicated yield trial. A positive correlation of thousand grain weight (TGW), harvest index (HI), and tiller number per meter (TNpM) with yield (YD) with significant GxE effect was observed. Further multivariate analysis of these traits contributed maximum to the effective yield. Thirty promising NILs were identified with Sec-1-/GluB3+ alongwith with high yield contributing parameters.

“…However, was stastically similar to genotype NERI-306 (plant height of 103.65 cm) .The statistical analysis of data between different genotypes indicates that significant effect on plant height was mainly due to genetic potential of genotypes and can also affected by environmental factors like temperature, water, sunlight and nutrient uptake during its cropping period. Similar findings have been reported by Reddy et al [5].…”

The field experiment was conducted during Rabi 2021-2022 genotypes at Wheat Breeding experimental Field, Naini Agriculture Institute, SHUATS, Prayagraj, Uttar Pradesh. The Soil of the experimental plots was sandy loam in texture with neutral soil reaction (pH 6.7). The experiment was laid out with six genotypes (NERI-301, NERI-302, NERI-303, NERI-304, NERI-305 and NERI-306) in a Randomized Block Design with four replications. Study revealed that growth parameters viz., higher plant height (105.26cm), number of effective tillers/hill (10.00/hill), and plant dry weight (22.13 g/plant) were recorded significantly higher for the genotype NERI-305.For yield attributing parameters viz., number of effective tillers (6.55/hill), number of grains/spike (63.07/spike),and test weight (49.38 g) were significantly highest for the genotype NERI-304, and yield parameters viz, grain yield (4.74 t/ha), harvest index (41.52%) were recorded significantly higher for the genotype NERI-304. spike length (13.35 cm) and straw yield (6.69t/ha) were r significantly highest for the genotype NERI-301. From the above findings gross return (1,18,500.00 INR/ha), net return (82,314.00 INR/ha) and Benefit cost ratio (2.27) were significantly highest for the genotype NERI-304.The genotype NERI-304 was found to be more potential as well as economically viable and productive over rest of the genotypes.

“…Significantly higher plant height was observed in variety DBW-187 (118.73) which is statistically at par to HD-3411(117.69), HD-3406(116.36), HD-3437(115.43) HD-3440(115.29) and HD-3436(114.47) The statistical analysis of data between different Genotypes indicates that significant effect on plant height was mainly due to genetic potential of Genotypes and can also affected by environmental factors like temperature, water, sunlight and nutrient uptake during its cropping period. Similar results were also reported by Reddy et al [5] Significantly higher number of tillers recorded in variety DBW-187(13.63) was significantly at par to HD-3411(13.54), HD-3249 (13.52), HD-3440(13.43), HD-2733(13.31), HD-3436(13.30) and HD-2967(13.25). Increase in growth parameters depends on irrigation by 90 per cent and nutrient uptake during vegetative stage, it is an importance factor during tillers formation stage and yield depends on number of tillers developed during vegetative stage which is mainly due to genetic diversity and higher inheritance of character of seeds.…”

A field experiment was conducted to find out growth and yield of ten wheat varieties in the Rabi 2021-2022 at Wheat Breeding experimental Field, Naini Agriculture Institute, SHUATS, Prayagraj (U.P.). Soil of experimental plots was sandy loam in texture with neutral soil reaction (pH 7.1). Experiment consists of ten varieties HD-3440, HD-3406, HD-2967, HD-3411, HD-3437, DBW-187, HD-3436, HD-3249, HD-2733, HD-3086 which are replicated four times in Randomized Block Design and evaluation was recorded. The results showed that growth parameters viz., higher plant height (118.73 cm), number of effective tillers/hill (13.63), dry weight (43.00 g) and yield attributing parameters viz., spike length (14.12 cm), no. of grains/spike (100.50), test weight (39.53 g), grain yield (4.21 t/ha), straw yield (6.26 t/ha), harvest index (40.10 %), were recorded significantly higher in DBW-187 variety. where DBW-187 variety was found to be more potential, viable and productive over rest of the varieties.
