Genetic analysis of grain weight in wheat [PDF]

open access: yesHeredity, 1986
The reciprocal monosomic analysis (RMA) technique of intervarietal chromosome manipulation was used to investigate the genetic control of grain weight in two varieties of wheat (Spica and Chinese Spring). The method enabled major genetic differences between the two varieties for this quantitative character to be assigned to individual chromosomes.

Yield Attributes Response to Nitrogen Fertilization in Low-Nitrogen Tolerant Hybrid Rice

open access: yesAgronomy, 2022
The development of low-nitrogen (N) tolerant varieties is an effective way to improve the use efficiency of N in rice and is crucial to the sustainable rice production in China.

Reinvestigation of THOUSAND-GRAIN WEIGHT 6 grain weight genes in wheat and rice indicates a role in pollen development rather than regulation of auxin content in grains [PDF]

open access: yesTheoretical and Applied Genetics, 2021
Phylogenetic and expression analyses of grain weight genes TaTGW6 and OsTGW6 and investigation of substrate availability indicate TGW6 does not regulate auxin content of grains but may affect pollen development. The THOUSAND-GRAIN WEIGHT 6 genes (TaTGW6 and OsTGW6) are reported to result in larger grains of wheat and rice by reducing production of ...

Studies on grain weight, protein content and germinating performance of the grains from different ear positions for barley

open access: yes浙江大学学报. 农业与生命科学版, 2001
Grain weight, protein content and germinating performance of the barley grains from different ear positions (top, middle and bottom) were measured. It is showed that grain weight of middle-positioned grains is higher than that of both top- and bottom ...

Transcriptomic and Physiological Response of Durum Wheat Grain to Short-Term Heat Stress during Early Grain Filling

open access: yesPlants, 2021
In a changing climate, extreme weather events such as heatwaves will be more frequent and could affect grain weight and the quality of crops such as wheat, one of the most significant crops in terms of global food security. In this work, we characterized

Comparative Effects of Heat Stress at Booting and Grain-Filling Stage on Yield and Grain Quality of High-Quality Hybrid Rice [PDF]

open access: yes, 2023
Rice plants are highly sensitive to high-temperature stress, posing challenges to grain yield and quality. However, the impact of high temperatures on the quality of high-quality hybrid rice during the booting stage, as well as the differing effects of ...

Superior grains determined by grain weight are not fully correlated with the flowering order in rice

open access: yesJournal of Integrative Agriculture, 2015
Rice panicles are composed of many branches with two types of extreme grains, the superior and the inferior. Traditionally, it has been well accepted that earlier flowers result in superior grains and late flowers generate inferior grains. However, these

Functional Analysis of OsCIPK17 in Rice Grain Filling

open access: yesFrontiers in Plant Science, 2022
We used mutant cipk17 and Nipponbare in field experiments to analyze agronomic traits, photosynthetic parameters, transcriptome, and gene expression. The results demonstrated cytoplasmic localization of OsCIPK17, while GUS allogeneic (A. thaliana) tissue-

Patterns of Influence of Meteorological Elements on Maize Grain Weight and Nutritional Quality

open access: yesAgronomy, 2023
Meteorological factors are one of the important factors that determine maize kernel weight and grain nutritional quality. Analyzing the influence of meteorological factors before and after anthesis on maize kernel weight and nutritional quality ...

Effects of radiation and temperature on tiller survival, grain number and grain yield in winter wheat [PDF]

open access: yes, 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,
