The Effect of Grain Position on Genetic Improvement of Grain Number and Thousand Grain Weight in Winter Wheat in North China [PDF]

Frontiers in Plant Science, 2018
Genetic improvements have significantly contributed to wheat production. Five wheat cultivars—widely grown in north China in the 1950s, 1990s, or 2010s—were grown in field experiments conducted in the 2014–2015 and 2015–2016 growing seasons.

A molecular framework for grain number determination in barley. [PDF]

Sci Adv, 2023
Flowering plants with indeterminate inflorescences often produce more floral structures than they require. We found that floral primordia initiations in barley ( Hordeum vulgare L.) are molecularly decoupled from their maturation into grains.

Natural variation in GNP3 determines grain number and grain yield in rice. [PDF]

Nat Commun
Grain number per panicle critically determines rice yield. Although many underlying genes have been reported, yet the molecular mechanisms linking ethylene to panicle development remain unclear. Here, we identify GRAIN NUMBER PER PANICLE 3 (GNP3) as a regulator of GNP through genome-wide association study (GWAS) combined with map-based cloning.

GW10, a Member of P450 Subfamily Regulates Grain Size and Grain Number in Rice [PDF]

Theoretical and Applied Genetics, 2021
Abstract Grain size and grain number play extremely important roles in rice grain yield. Here, we identify GW10 , which encodes a P450 subfamily protein and controlls grain size and grain number by using Lemont ( tropical japonica ) as donor parent and HJX74 ( indica ) as recipient parent. The GW10 locus was mapped into a 20.1 kb region

Identification of SMG3, a QTL Coordinately Controls Grain Size, Grain Number per Panicle, and Grain Weight in Rice. [PDF]

Front Plant Sci, 2022
Grain size, grain number per panicle, and grain weight are key agronomic traits that determine grain yield in rice. However, the molecular mechanisms coordinately controlling these traits remain largely unknown. In this study, we identified a major QTL, SMG3, that is responsible for grain size, grain number per panicle, and grain weight in rice, which ...

SMALL GRAIN 11 Controls Grain Size, Grain Number and Grain Yield in Rice [PDF]

Rice, 2016
Grain size is one of key agronomic traits that determine grain yield in rice. Several regulators of grain size have been identified in rice, but the mechanisms that determine grain size and yield remain largely unknown.Here we characterize a small grain (smg11) mutant in rice, which exhibits small grains, dense panicles and the increased number of ...

The da1 mutation in wheat increases grain size under ambient and elevated CO2 but not grain yield due to trade‐off between grain size and grain number

Plant-Environment Interactions, 2021
Why this research Matters Grain size is potentially yield determining in wheat, controlled by the ubiquitin pathway and negatively regulated by ubiquitin receptor DA1.

Effect of delayed sowing on grain number, grain weight, and protein concentration of wheat grains at specific positions within spikes

Journal of Integrative Agriculture, 2023
Delays in sowing have significant effects on the grain yield, yield components, and grain protein concentrations of winter wheat. However, little is known about how delayed sowing affects these characteristics at different positions in the wheat spikes ...

Genome-Wide Association Study for Spike Traits and Distribution of Two QTLs for Grain Number in Chinese Wheat Cultivars

Agronomy, 2023
Spike traits play an important role in improving wheat yield. However, the application of reported spike-related loci remains unclear. Here, we assessed six spike-related traits across seven different environments using 406 wheat accessions.

Identification and Validation of Quantitative Trait Loci for Grain Number in Rice (Oryza sativa L.)

Agronomy, 2020
Grains number is one of the most important agronomic traits in the determination of rice productivity. To explore the underlying genetic basis of grain number in rice, quantitative trait locus (QTL) analysis was performed using three recombinant inbred ...
