Heterotic loci identified for plant height and ear height using two CSSLs test populations in maize

Brassinosteroid regulation of plant height in maize

Identification of heterotic loci associated with grain yield and its components using two CSSL test populations in maize

Heterosis has widely been used to increase grain yield and quality. In this study, the genetic basis of heterosis on grain yield and its main components in maize were examined over 2 years in two locations in two test populations constructed from a set of 184 chromosome segment substitution lines (CSSLs) and two inbred lines (Zheng58 and Xun9058). Of the 169 heterotic loci (HL) associated with ...

Genetic Relationship of Stalk Strength and Ear Height in Maize

creased by 22.5% over five cycles of selection for high RPR in MoSCSSS. The correlation between RPR and The rind penetrometer is an effective tool for measuring stalk EH is of interest in terms of direct vs. indirect selection strength in an effort to improve maize (Zea mays L.) germplasm for stalk lodging resistance. However, previous studies have indicated a for stalk strength. That is, to wh...

Combined Linkage and Association Mapping Reveals QTL and Candidate Genes for Plant and Ear Height in Maize

Plant height (PH) and ear height (EH) are two very important agronomic traits related to the population density and lodging in maize. In order to better understand of the genetic basis of nature variation in PH and EH, two bi-parental populations and one genome-wide association study (GWAS) population were used to map quantitative trait loci (QTL) for both traits. Phenotypic data analysis revea...

Quantitative trait locus analysis for ear height in maize based on a recombinant inbred line population.

Maize (Zea mays L.) is among the crops with the greatest worldwide economic importance. Ear height is a very important trait that is considered necessary in maize and is related to morphology, lodging, and yield. To realize its genetic basis, an F9 recombinant inbred line population and a genetic map consisting of 101 simple sequence repeat markers were used to detect the quantitative trait loc...
