摘要

碳水化合物胁迫会降低稻米的米粒大小和头米率,并增加垩白度。本研究旨在比较低垩粒和优质栽培品种的碾米率、垩白粒率以及圆锥花序上、中、下三部分的粒径。2019 年和 2022 年在博蒙特种植了低垩粒和垩白长粒水稻品种。收割圆锥花序,将其分为顶部、中部和底部,并对谷粒大小、头米率和垩白度进行表型。低垩度栽培品种普雷西迪奥(Presidio)和凯本内特(Kaybonnet)从圆锥花序上部到中部的谷粒面积减少率较高。这可以缓解导致垩白的碳水化合物压力。还对水稻栽培品种的 Chalk5 和 OsPPDK 进行了基因分型。低垩度栽培品种与低垩度莱蒙的 Chalk5 具有相同的等位基因。与测试的栽培品种相比,Presidio 的 OsPPDK 具有不同的等位基因。与 Chalk5 的基因分型结果一致,Presidio 和 Kaybonnet 的白垩度低于 LaGrue 和 Leah。初级圆锥花序分枝数与头米率呈正相关。要提高育种效率以获得优质谷粒,需要对高主圆锥花序分枝数以及低垩白和部分垩白谷粒比例进行表型筛选。

Grain Quality of Panicle Portions in Chalky and Low-Chalky Rice Cultivars.

Carbohydrate stress reduces grain size and head rice percentage and increases the chalkiness in rice. This study aims to compare low and high-quality cultivars for their milled rice and chalky grain percentages, as well as grain size, in the top, middle, and bottom panicle portions. Low-chalky and chalky long-grain rice cultivars were grown at Beaumont in 2019 and 2022. Panicles were harvested, partitioned into top, middle, and bottom portions, and phenotyped for grain size, head rice percentage, and chalkiness. Grain area reduction percentage from top to middle panicle portions is higher in the low-chalky cultivars, Presidio and Kaybonnet. This could relieve the carbohydrate stress that leads to chalkiness. The rice cultivars were also genotyped for Chalk5 and OsPPDK. The low-chalky cultivars had the same allele as the low-chalk Lemont for Chalk5. Presidio had a different allele for OsPPDK compared with the cultivars tested. Consistent with the genotyping result for Chalk5, Presidio and Kaybonnet had lower chalkiness than LaGrue and Leah. There was a positive correlation between the number of primary panicle branches and head rice percentage. The improvement in breeding efficiency for high grain quality requires phenotypic screening for a high number of primary panicle branches and for low chalky and partially chalky grain percentages.

期刊介绍: Rice aims to fill a glaring void in basic and applied plant science journal publishing. This journal is the world''s only high-quality serial publication for reporting current advances in rice genetics, structural and functional genomics, comparative genomics, molecular biology and physiology, molecular breeding and comparative biology. Rice welcomes review articles and original papers in all of the aforementioned areas and serves as the primary source of newly published information for researchers and students in rice and related research.
