Allopolyploidization, that is, concomitant merging and doubling of two or more divergent
genomes in a common nucleus/cytoplasm, is known to instantly alter genomewide …

Heterosis, or hybrid vigour, describes the superior performance of heterozygous hybrid
individuals compared with their homozygous parental inbred lines. Although heterosis has …

Heterosis contributes greatly to crop production, but the genetic basis of heterosis is not fully
understood. To identify heterotic loci (HLs) for grain yield, 12 yield traits were evaluated in …

Abstract North Carolina design III (NCIII) is one of the most powerful and widely used mating
designs for understanding the genetic basis of heterosis. However, the quantitative trait …

Background Neo-tetraploid rice, which is a new germplasm developed from autotetraploid
rice, has a powerful biological and yield potential and could be used for commercial …

The complex structure of a single Mendelian factor widespread in the Asian cultivated rice
(Oryza sativa) and its wild progenitor (Oryza rufipogon) that caused diverse phenotypes in …

Heterosis, or hybrid vigor, represents one of the greatest contributions of genetics to the
improvement of major crops such as maize and rice, which is intensively studied and …

Abstract Heading date 1 (Hd1) is one of the major determinants of flowering time and
regional adaptability in rice (Oryza sativa L.), because there is a significant correlation …

Rice yield and heading date are two distinct traits controlled by quantitative trait loci (QTLs).
The dissection of molecular mechanisms underlying rice yield traits is important for …

Increasing crop yield is a major challenge for agricultural scientists because of an ever-
increasing world population and a finite amount of arable land. Rice (Oryza sativa) is a …
