Abstract Phenology is critical to crop adaptation. We grew 24 chickpea genotypes in 12 environments analyse: the environmental and genotypic drivers of phenology; associations between phenology yield; phenotypes associated with allelic variants three flowering related candidate loci: CaELF3a ; a cluster FT genes on chromosome 3; region 4 an orthologue floral promoter GIGANTEA . A simple model 3 genotype-specific parameters explained differences response daylength. Environmental factors causing flower abortion, such as low temperature radiation high humidity, led longer flowering-to-podding interval. Late podding poor partition grain, limiting yield favourable environments. Sonali, carrying early allele Caelf3a ( elf3a ), was generally earliest set pod, had biomass but highest harvest index. Genotypes combining orthologues FTdel , where deletion intergenic FTa1-FTa2 slow development, usually featured reproduction index, returning emphasise importance pod set, rather than flowering, target for breeding, agronomic, modelling applications. Highlight This paper analyses genetic controls its effects grain yield, multi-environment trial including varying combinations genes.

Continuing to raise the potential yield of wheat through breeding is essential for global food security. Past progress has largely been associated with greater grains/m2 (GN), critical period determination which relates spike growth, GN often closely related dry weight at anthesis (g/m2). This focussed review outlines importance duration (Ds, in days or °Cdays) and questions how it may be increased genetically, relying partly on long involvement authors this field, primarily lower latitude crops spring-type wheat. Ds further defined as interval between flag leaf emergence first anthesis, each across 50 % culms any crop, a encompassing most accumulation matter, turn determining floret survival final fertile numbers/m2. Natural temperature variation manipulation, particularly field crops, confirm dependence temperature, °Cdays varies from about 300–500, depending photoperiod. Evidence points stronger influence night than day Ds, while maintaining close positive relationship GN. However, genetic response appears very minor. inversely photoperiod, again expected effects weight, florets Extended photoperiod during showed greatest reduction per advance anthesis. responses can major sensitivity alleles present. A experiment unique reduced treatment demonstrated strong effect GN, especially fully recessive photoperiod-sensitive isoline. While more recent varieties tend have longer experiments targeting selection intervals delivered little change low heritability. Field shortening studies needs testing proof concept. Better are also needed. At same time, knowledge molecular basis such that gene editing surely ripe tackle challenge down-regulating only period, thereby increasing Exogenous application plant development regulators appropriate stage provide way forward.

Episodes of extreme weather, such as high temperatures and heavy rains causing waterlogging, have been becoming more frequent due to climate change, posing risks crops reducing growth yield. While the impact these stresses has individually studied, there is a significant gap in understanding their combined effects within same growing season. There were only 15 studies rigorous literature addressing waterlogging. None explicitly examined whether additive (penalties close sum individual penalties), synergistic (more severe or antagonistic (less penalties). We aimed propose sound hypothesis on most likely type interaction between two stressors. Reviewing scarce we found, against expectations, that interactions common, followed by cases effects, with being rare. Notably, while primary concern virtually all was crop yield, them focused exclusively leaf-level traits, whose responses did not correlate well yield responses. This preliminary analysis provides solid roots for hypothesizing waterlogging interact antagonistically; i.e., plants might develop some resilience when exposed one stress, potentially other. Should this be accepted, considering physiological traits but also, mainly, major crops, would less pessimistic view expected outcome increased frequency temperature

ABSTRACT Drought stress reduces cereal crop growth and yield due to modifications interactions between sink source. However, little research has investigated multiple carbon sources their relationships with capacities, especially in response drought at different stages. The objective of this study was thus examine two major (i.e., photosynthetic assimilation the flag leaf remobilisation pre‐anthesis reserves stems) strength phenological A greenhouse experiment conducted five water regimes: well‐watered (WW), progressive (PD), (DS) during vegetative (DS‐V), early reproductive (DS‐ER), post‐anthesis (DS‐PA). Compared WW regime, DS‐V treatment reduced shoot biomass, grain yield, number grains per pot, weight, harvest index, water‐soluble carbohydrates stems despite recovered photosynthesis after rehydration. Wheat plants subject DS‐PA exhibited rate but greater depletion filling relative regime. Grain positively correlated residual late‐season rates. This demonstrated losses associated changes source capacities stages showcased predominant role filling.
