Effects of Radiation and Temperature on Tiller Survival, Grain Number and Grain Yield in Winter Wheat

open access: yesAnnals of Botany, 1987
Effects of the environment on shoot survival were studied in winter wheat cv. Avalon grown in microplots at a density of 247 plants m−2. The incident radiation and mean temperature were altered during one of three periods of between 14 and 29 d duration, the first (P1) starting at the end of tiller production and the last (P3) finishing near the end of

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

open access: yesJournal 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 ...

Genetic gain in grain yield and main agronomic traits of winter wheat during the past 90 years in Pannonian plain [PDF]

open access: yesSelekcija i Semenarstvo, 2022
This study aimed to quantify the changes in grain yield and main agronomic traits in winter wheat cultivars registered during the past 90 years . A field trial with 18 winter wheat cultivars registered from 1930 to 2016 was conducted at the experimental ...

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

open access: yesTheoretical 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

Wheat Escapes Low Light Stress by Altering Pollination Types

open access: yesFrontiers in Plant Science, 2022
Although low light stress seriously affects florets fertility and grain number during the reproductive period, crops can be fertilized by heterologous pollen to alleviate the reduction of grain number. However, wheat is strongly autogamous, how to change

Grain Yield Formation and Nitrogen Utilization Efficiency of Different Winter Wheat Varieties under Rainfed Conditions in the Huang-Huai-Hai Plain

open access: yesAgronomy, 2023
Winter wheat production is threatened by drought stress under rainfed conditions; thus, screening high- and stable-yielding wheat varieties to ensure the sustainable development of wheat production and food security in the Huang-Huai-Hai Plain (HHHP) is ...

Contribution of genes related to grain number (Gn1a and WFP) introgressed into NERICA 1 to grain yield under tropical highland conditions in central Kenya

open access: yesPlant Production Science, 2023
In Kenya and many other African countries, improving rice productivity is vital for future food security. To improve rice productivity in Kenya, near-isogenic lines (NIL) were developed by introducing Gn1a and WFP, genes that function to increase grain ...

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

open access: yesRice, 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 ...

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

open access: yesAgronomy, 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 ...

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

open access: yesAgronomy, 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.
