Phytohormone-Mediated Molecular Mechanisms Involving Multiple Genes and QTL Govern Grain Number in Rice. [PDF]
Front Genet, 2020 Increasing the grain number is the most direct route toward enhancing the grain yield in cereals. In rice, grain number can be amplified through increasing the shoot branching (tillering), panicle branching, panicle length, and seed set percentage ...

Pleiotropic Effect of GNP1 Underlying Grain Number per Panicle on Sink, Source and Flow in Rice. [PDF]
Front Plant Sci, 2020 Rice yield potential is largely determined by the balance among source capacity, sink strength, and flow fluency. Our previous study indicated that the gene GNP1 encoding gibberellin biosynthesis gene GA20ox1 affects grain number per panicle (GNP) in ...

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

Allele mining for the grain number gene An-1 in rice (Oryza sativa L.)
Electronic Journal of Plant Breeding, 2021 Rice yield has attained a plateau and hence the enhancement of grain yield is indispensable to feed the growing population, which could be achieved by the identification of superior alleles in the existing germplasm. Any variation in the pleiotropic gene,

Dissecting the trade-off of grain number and size in wheat
Planta, 2021 Principal component and meta-QTL analyses identified genetic loci affecting the trade-off of wheat grain number and size, which could provide opportunities to optimize local breeding strategies for further yield improvement. Grain yield of wheat is complex, and its physiological and genetic bases remain largely unknown.

OsSPL18 controls grain weight and grain number in rice
Journal of Genetics and Genomics, 2019 Grain weight and grain number are two important traits directly determining grain yield in rice. To date, a lot of genes related to grain weight and grain number have been identified; however, the regulatory mechanism underlying these genes remains largely unknown.

Strategies of grain number determination differentiate barley row types [PDF]
Journal of Experimental Botany, 2020 Abstract Gaining knowledge on fundamental interactions of various yield components is crucial to improve yield potential in small grain cereals. It is well known in barley that increasing grain number greatly improves yield potential; however, the yield components determining grain number and their association in barley row types are ...
