Yellow rust and heat stress adversatively impact the growth production of bread wheat in particular under rising adverse environmental conditions. Stability grain yield is a pivotal purpose plant breeders to improve ensure global food security especially abrupt climate change. The objective this study was assess performance stability diverse genotypes for yellow resistance, stress, traits. studied were evaluated two different locations sowing dates (timely late sowing) during growing seasons. obtained results displayed significant differences among tested locations, dates, most measured measurements field conditions including final severity (FRS), average coefficient infection (ACI), area disease progress curve (AUDPC) revealed that Giza-171, Misr-1, Gemmeiza-12, Shandweel-1, Sids-13, Line-1, Line-2, Line-55 had better resistance. Based on sensitivity measurements, Line-1 Line-2 followed by Line-35, Shandweel-1 classified as more tolerant compared with remaining genotypes. Line-55, Misr-1 able maintain acceptable agronomic timely all environments. Different statistical procedures employed explore adaptability i.e., joint regression, stratified ranking, Wricke's Ecovalence values, cultivar superiority, additive main effects, multiplicative interaction (AMMI), AMMI value, genotype plus genotype-by-environment (GGE). applied parameters quite similar describing indicated Sids-12, desirable stable. heatmap hierarchical clustering exploited dividing into clusters based resistance tolerance indices, performance. best tolerance, Sids-13. In conclusion, our findings provide evidence utilizing promising breeding programs improving mainly

Abstract Small grains provide agronomic benefits that are critical to the success of organic production, and opportunities within local food movements create expanded markets for small grains. However, diversifying rotations with can present challenges related infrastructure, markets. Here, we draw upon over two decades integrated research Extension efforts support grain production in Upper Midwest, Northeast, other regions United States where these crops underutilized. Lessons learned have led development guiding principles a systems‐level approach regional production. Forming innovative partnerships between farmers, researchers, end users is critical. This enables research, adjust needs, adapt available foster economies. The key lie ahead also discussed, especially adapting practices conditions changing climates. highlighted here will increase resilience farms across expand adoption

Determining adaptability of farmer bred spring wheat (Triticum aestivum L.) genotypes to Canadian organic production using stability analysis

Plant Breeding, Journal Year: 2024, Volume and Issue: unknown

Published: May 20, 2024

Abstract Participatory plant breeding (PPB) is a collaborative process between farmers, breeders and researchers to create germplasm specifically bred for target environments. We sought examine the yield performance adaptability of genotypes from an organic PPB wheat programme under management across Canadian prairies. evaluated 25 farmer 6 commercial cultivars in locations Alberta, Saskatchewan Manitoba, totalling 12 The top performers most responsive higher environments were three (BL34‐SW, BL43C‐TM BJ13‐GW) one check cultivar (Vesper). Genotype plus genotype by environment (GGE) biplot analysis indicated that (BL23‐AS) (Vesper) demonstrated high greater adaptation than other tested. Two registered (AAC Brandon Jake) had low poor adaptation, as did (PWA10B‐LD). Yield was positively strongly correlated with height, anthesis mature biomass kernel number per unit area. results provide evidence early generation selection effective strategy discovering excellent production systems Canada.

Yield Stability and Adaptability of Spring Barley (Hordeum vulgare) Varieties in Polish Organic Field Trials

Agronomy, Journal Year: 2024, Volume and Issue: 14(9), P. 1963 - 1963

Published: Aug. 29, 2024

In the next few years, demand for organic crops, including barley, will grow. Barley is one of world’s most important crops cultivated food and feed. With forecasted increase in cropped area, there a need stable, well-adapted high-yielding varieties. The aim this study was to assess yield stability ten varieties tested Polish post-registration trials years 2020–2022. For purpose, we fitted linear mixed model on plot data. Additionally, each variety, calculated probability falling certain threshold. It shown that Bente variety highest-yielding among Pilote stable terms Shukla’s variance. Furthermore, three varieties, lowest values simultaneous selection index below threshold were obtained. We can, therefore, conclude should be promoted cultivation. Moreover, new suitable farming can bred from

One of the major tasks faced by wheat breeders in Uzbekistan is to enhance genotypes’ adaptability soil and other environmental conditions improve grain quality, making country self-sufficient grains later becoming an exporter. Better results are achievable using world collection, including CIMMYT germplasm. Determination positive correlation physiological traits new cultivars, importance indicators water balance with productivity, vital role these productivity level were chief concerns. The timely study evaluated heat resilience, rust resistance, yield bread genotypes. Bread germplasm obtained from a background artificial infection yellow incurred scrutiny for their resistance. A 15% incidence was detectable seven genotypes; however, necrosis quickly formed around symptoms disease plant leaves, preventing its further development. Resistant accessions, i.e., 1088, 1164 (R), 1006, 1251 (MR), occurred as moderately resistant, showing high leaf area yield. average value genotypes low, mainly due two rust-resistant samples, 1000-grain weight 34.8 g 34.6 g, respectively, per spike lower than average. chlorophyll b, total chlorophyll, carotenoid content, relative flag area, production К-1088 К-1164 gained assessment, revealed be physiologically effective under field Tashkent, Uzbekistan.
