... The study aimed to analyze the agronomic performance of 11 safflower genotypes using adaptability and stability methods, while identifying safflower genotypes with stable behavior and a high grain yield in different environments of the Brazilian Cerrado. Ten lines and a cultivar of safflower were evaluated in four environments in the Brazilian conditions. Our results revealed the genotypes P30, P3 ...

Abstract:
... Flower size, a primary agronomic trait in breeding of ornamental plants, is largely determined by petal expansion. Generally, ethylene acts as an inhibitor of petal expansion, but its effect is restricted by unknown developmental cues. In this study, we found that the critical node of ethylene-inhibited petal expansion is between stages 1 and 2 of rose flower opening. To uncover the underlying reg ...

Abstract:
... Plant height is the main agronomic character used to measure the vertical growth and developmental abilities of plant. Cucumber is a popular greenhouse vegetable in Northwest China, and its production is principally limited by water and temperature. However, few studies have simulated water- and temperature-driven cucumber heights in solar greenhouses; in this paper, we explored these optimum grow ...

Abstract:
... Organ size is an important agronomic trait. Small peptides function in various stages of plant growth, but their regulatory mechanisms in organ growth remain poorly understood. Here, we characterize a novel small peptide, AtZSP1, which positively regulates organ size in Arabidopsis. Loss‐of‐function mutant atzsp1‐1 exhibited small organs, whereas AtZSP1 overexpression plants (p35S:AtZSP1#1) produc ...

Abstract:
... BACKGROUND: Foliar application of highly concentrated ZnSO₄ fertilizer improves Zn biofortification in wheat grains. However, excess ZnSO₄·7H₂O concentration (≥5 g kg⁻¹, w v⁻¹) has been associated with leaf burn and yield loss, necessitating Zn sources with a high threshold concentration. The aim of this study, based on a 2 year field experiment conducted on wheat cultivated in acidic and alkaline ...
... Genetic biofortification through breeding offers sustainable solution to the micronutrient malnutrition problems in the target countries. Great progress has been made in the past decade in transferring alleles for high-zinc (Zn) and iron (Fe) from diverse genetic resources into elite wheat breeding lines. However, the major challenge is to maintain simultaneous and high rates of genetic gains for ...

... Truncated antenna size of photosystems and lower leaf chlorophyll content has been shown to increase photosynthetic efficiency and biomass accumulation in microalgae, cyanobacteria and higher plants grown under high-density cultivation conditions. Here, we have asked whether this strategy is also applicable to a major crop by characterizing the barley mutant happy under the sun 1 (hus1). The pale ...

Abstract:
... The stem diameter, an important agronomic trait, affects cucumber growth and yield. However, no genes responsible for cucumber stem diameter have been identified yet. In this study, the stem diameter of 88 cucumber core germplasms were measured in spring 2020, autumn 2020 and autumn 2021, and a genome-wide association study (GWAS) was carried out based on the gene sequence and stem diameter of cor ...
... Lodging is an important agronomic trait related to crop yield and is easily susceptible to environmental influences. In this study, a recombinant inbred line population from soybean (Glycine max (L.) Merr.) Hefeng 25×Dongnong L28 including 109 lines was used to identify quantitative trait loci (QTLs) related to soybean lodging. Seven QTLs were identified in the three environments (Harbin in 2 ...

Abstract:
... In-situ composting is an efficient method for the dispose of crop residues. However, the high organic carbon content and low water-holding capacity of corn (Zea mays L.) straw can easily result in a slow composting process with high nutrient loss. In this study, compressed corn straw blocks was a control (S), straw mixed with earthworm casts (SE), straw mixed with biochar (SB), straw mixed with ea ...

Abstract:
... Accurate estimation of radiation use efficiency (RUE) at variable timed sowing dates will enhance the prediction of plant dry matter accumulation. The objectives of this study were to (1) determine the impact of three sowing dates on the productivity, performance, and economic feasibility of three biomass sorghum hybrids and (2) evaluate the variability of RUE in the production of biomass sorghum ...
... Lactuca indica L. is an undomesticated medicinal crop in the Asteraceae family. The study was carried out to identify elite genotypes for lettuce cultivation and breeding improvement. Data was recorded for 19 morphological and developmental traits across 38 accessions (Acc). The genotypic mean square variance was significant for all characters. The higher extent of genotypic and phenotypic coeffic ...

Abstract:
... Ideotypic characteristics of durum wheat associated with higher yield under different water and temperature regimes were studied under Mediterranean conditions. Six semi-dwarf cultivars with contrasting agronomic performance were grown during two consecutive years under winter-planted rainfed and winter-planted support-irrigation conditions and a late-planting trial under support irrigation, at th ...

Abstract:
... Rice panicle apical abortion (PAA) is a detrimental agronomic trait resulting in spikelet number reduction and yield loss. To understand its underlying molecular mechanism, we identified one recessive PAA mutant tutou2 from the offspring of tissue cultures. The mutation locus was finely mapped to a 75-kb interval on the long arm of chromosome 10. Sequence analysis revealed a single nucleotide subs ...
... Organic materials have a nonreplaceable role to improve soil quality and productivity. Yet, processes related to decomposition and nutrient supply capacity are restricted under nutrient-depleted soils. Thus, a field experiment was conducted to evaluate the decomposition rate of leaf litter mixtures treated with mineral nitrogen (N), phosphorous (P), and sulfur (S) fertilizer in the form of NPS (19 ...

Abstract:
... Provitamin A-enriched maize (Zea mays L.) is an important complementary food staple for combating vitamin A deficiency (VAD) in high maize-producing and maize-consuming countries of sub-Saharan Africa (SSA). However, frequent drought is a major abiotic factor that retards maize growth, resulting in yearly fluctuations in grain yield. Development of provitamin A-enriched maize varieties resilient t ...
... KEY MESSAGE: Introducing Agropyron cristatum chromosome 1P into common wheat can significantly reduce the plant height and leaf size, which can improve the plant architecture of common wheat. A new direction in crop breeding is the improvement of plant architecture for dense plantings to obtain higher yields. Wild relatives carry an abundant genetic variation that can increase the diversity of gen ...
... The wheat Green Revolution Rht-B1b and Rht-D1b dwarfing alleles are associated with increased grain yields but also with reduced early growth and seedling emergence, especially if sowing conditions are unfavourable. The gibberellic acid-responsive, mutagen-derived Rht18 dwarfing gene was backcrossed from durum wheat (Triticum turgidum subsp. durum L.) cv. Icaro into tall bread wheat (Triticum aest ...
... The faba bean (Vicia faba) is a temperate grain legume, that is regaining interest due to the high demand for food and feed uses and the environmental services provided. The parasitic weed broomrape (Orobanche crenata) appears as the major constraint to agricultural production in the Mediterranean Basin. The yield stability can be managed by adjusting agronomic practices and breeding for adaptatio ...
