Understanding how numerous quantitative trait loci (QTL) shape phenotypic variation is an important question in genetics. To address this, we established a permanent population of 18,421 (18K) rice lines with reduced structure. We generated reference-level genome assemblies the founders and genotyped all 18K-rice through whole-genome sequencing. Through high-resolution mapping, 96 high-quality candidate genes contributing to 16 traits were identified, including
Abstract Exploitation of crop heterosis is crucial for increasing global agriculture production. However, the quantitative genomic analysis was lacking, and there currently no effective prediction tool to optimize cross-combinations. Here 2,839 rice hybrid cultivars 9,839 segregation individuals were resequenced phenotyped. Our findings demonstrated that indica – hybrid-improving breeding a process broadened genetic resources, pyramided breeding-favorable alleles through combinatorial...
This study aimed to explore the genetic information about yield traits in perennial Chinese rice "Shendao3#" and provide a series of theoretical bases for innovative utilization germplasm. The F2 population derived from cross between one annual "XiqingzaoB" was developed identify QTLs’ underlying yield-related traits. Fifteen including plant height, panicle plant-1, thousand-grain weight were measured QTL mapping. software packages Excel 2010, GraphpadPrism 5.0, QTLIciMapping 4.10...
<title>Abstract</title> "Shengdao3<sup>#</sup>" is a novel type of perennial rice germplasm native to China. And so, this study aimed explore the genetic information about yield traits in Chinese and provide series theoretical bases for innovative utilization germplasm. The F<sub>2</sub> population derived from cross between common "XiqingzaoB" was developed identify QTLs underlying yield-related traits. Fifteen including plant height, panicle plant<sup>− 1</sup>, thousand-grain weight were...
Since the inception of hybrid rice technology 50 years ago, it has not only substantially increased yield per unit area but also expedited development high-quality varieties. However, evolutionary characteristics quality remain unclear. To address this gap, is imperative to leverage more representative and comprehensive resources analyze phenotypic variation diversity its primary genetic basis, thereby offering efficient guidance for molecular breeding. In study, we selected 2,618 varieties...
Abstract Overwintering (OW) rice can survive through the natural cold-winter field environment, exhibit a strong root system activity, sprout from tillering node in following spring, and apparently reveal cold resistance of during whole growth stage. The successful utilization cold-resistant is most economical strategy for cultivar breeding. This work aims to identify OW future development cultivars. Altogether 1034 Chinese cultivars were evaluated their responses low temperatures under...
