In any hybridization program, recognition of the best combination of two (or more) parental
genotypes to maximize variance within related breeding populations, and as a result the …

Grain yield in rice is a complex trait multiplicatively determined by its three component traits:
number of panicles, number of grains per panicle, and grain weight; all of which are typical …

Rice (Oryza sativa), a major staple throughout the world and a model system for plant
genomics and breeding, was the first crop genome sequenced almost two decades ago …

Increasing grain yield is a long-term goal in crop breeding to meet the demand for global
food security. Heterosis, when a hybrid shows higher performance for a trait than both …

Grain yield in many cereal crops is largely determined by grain size. Here we report the
genetic and molecular characterization of GS3, a major quantitative trait locus for grain size …

Exploitation of heterosis is one of the most important applications of genetics in agriculture.
However, the genetic mechanisms of heterosis are only partly understood, and a global view …

Yield potential, plant height and heading date are three classes of traits that determine the
productivity of many crop plants. Here we show that the quantitative trait locus (QTL) Ghd7 …

The GS3 locus located in the pericentromeric region of rice chromosome 3 has been
frequently identified as a major QTL for both grain weight (a yield trait) and grain length (a …

Improved genotypes developed by plant breeding remain pivotal to global food security. In
the wake of ever-increasing human population, declining agricultural resources and the …

Asian cultivated rice consists of two subspecies: Oryza sativa subsp. indica and O. sativa
subsp. japonica. Despite the fact that indica rice accounts for over 70% of total rice …
