“…Wheat is a major grain crop due to its nutritional value and wide acceptability worldwide [14,23,24]. However, adversities associated with climate change are major challenges to meet the ever-increasing demand of food supply with the increasing population [25][26][27].…”

Stem reserves in grain crops are considered important in grain filling under post-anthesis stress in the absence/low availability of photosynthetic assimilates. Considerable variation is present among genotypes for stem reserve translocation in wheat. Therefore, this study aimed to exploit the phenotypic variation for stem reserve translocation in wheat under control and chemically induced stress conditions. The phenotypic variation among six parents and their corresponding direct cross combinations was evaluated under induced stress conditions. The results signify the presence of considerable variation between treatments, genotypes, and treatment-genotype interactions. The parent LLR-20 depicted the highest translocation of dry matter and contribution of post-anthesis assimilates under induced-stress conditions. Similarly, cross combinations Nacozari × LLR22, Nacozari × LLR 20, Nacozari × Parula, Nacozari × LLR 21, LLR 22 × LLR 21, and LLR 20 × LLR 21 showed higher source-sink accumulation under induced-stress conditions. The selected parents and cross combinations can be further utilized in the breeding program to strengthen the genetic basis for stress tolerance in wheat.

“…The production also declined by 3.9% to 26.394 million tonnes against 27.464 million tonnes a year before (Anon., 2022). Farmers need better varieties and production technology for improved livelihood supplied by plant breeders (Lantican et al, 2016;Sarfraz et al, 2016). These newly developed varieties increase the pace of adoption as these adjust for biotic and abiotic stresses across multiple environments (Witcombe et al, 2016;Shaukat et al, 2021).…”

Wheat Research Institute (WRI), Faisalabad, Pakistan, a premier foundational birthplace of the Green revolution in Pakistan, has played a vital role in attaining food self-sufficiency. Latest grown varieties have succumbed to ever-changing pathogens, unable to stand in the fields. Hence, the initiative to develop an indigenous type to withstand high disease pressure producing better grain yield transpired during 2008–2009, with the hybridization of Dilkash-20 (WBLL*2/4/SNI/TRAP#1/3/KAUZ*2/TRAP//KAUZ/5/ PB.96//LU26/HD2179). It proceeded with segregating generations from F2 to F7 from 2009 to 2016. During 2016–2017 and 2017–2018, its testing followed at station yield trials, including Preliminary (A) and Regular (B), under code V-16005. It produced a significantly higher yield (10.86% and 10.40%) than the check varieties (Faisalabad-08 [FSD-08] and Punjab-11 [PB-11]). In provincial trials, it out-yielded a check variety by 4.06%. Testing in national yield trials, line V-16005 produced 17.40% and 12.03% higher grain yield than check cultivars during 2018–2019 and 2019–2020, respectively. It yielded better when planted on the first 10 days of November with a 100 kg ha-1 seed rate and 120:90:60 NPK (kg ha-1) fertilizer rate. The Dilkash-20 variety is a medium-height (105–115 cm), semi-erect producing 425 tillers per m2, with 119 days to heading and 145–150 days to maturity. It is of excellent quality, with protein (15.1%), starch (52.7%), gluten (28.7%), and test weight (72.1 kg hl-1), highly suitable for chapatti making. It has an effectual, durable resistance against brown and yellow rusts based on adult plant resistance genes. Therefore, the Punjab Seed Council approved Dilkash-20 for general cultivation throughout the irrigated areas of Punjab.

“…Symptoms related to the phenotypic structure of wheat have been frequently evaluated in previous studies, and to date, methods adapted to genetic backgrounds have been developed for many QTL analyzes using a variety of methods, but research continues (Yang et al, 2021;Griffiths, 2022). RAPDs were the first DNA markers used in genomic research for genotyping, as well as QTL mapping by PCR, because they are easier to manage, require less time, and do not require sequential information (Williams et al, 1990;Raheel et al, 2015, Sarfraz et al, 2020. Milad and colleagues identified RAPD and ISSR markers linked to flag leaf senescence gene in wheat under drought stress and QTL mapping for flag leaf senescence gene in the F2 population, using bulked segregant analysis (Milad et al, 2011).…”

Global climate change causes an increase in frequency and intensity of abiotic stress factors that negatively impact plants. Drought is a common environmental problem that negatively affects plant growth and productivity. The presence of the gene locus associated with flag leaf senescence in wheat plant genotypes exposed to drought stress was investigated using RAPD OPH13 and RAPD OPU06 markers. Based on the analysis of electrophoretic profiles of PCR results, the expected 450 bp fragments in 39 wheat genotypes and 340 bp fragments in 36 genotypes were synthesized. Results confirm the presence of the gene locus in these genotypes that ensures flag leaf senescence, which is an indicator of drought tolerance. The studied gene locus was absent in 31% of genotypes analyzed using the RAPD OPH13 marker and in 40% of genotypes with the RAPD OPU06 marker. It is proposed to use this locus, which ensures the physiological youth of the flag leaf, in future selection programs.
