Heterosis refers to the superior performance of hybrids over their parents, which is a general
phenomenon occurring in diverse organisms. Many commercial hybrids produce high yield …

In the past, rice hybrids with strong heterosis have been obtained empirically, by developing
and testing thousands of combinations. Here, we aimed to determine whether heterosis of …

Heterosis of grain yield is closely associated with heading date in crops. Gene combinations
of the major heading date genes Ghd7, Ghd8, and Hd1 play important roles in enhancing …

Y900 is one of the top hybrid rice (Oryza sativa) varieties, with its yield exceeding 15 t· hm−
2. To dissect the mechanism of heterosis, we sequenced the male parent line R900 and …

Because of the tremendous advances in functional genomics and the current availability of a
large number of superior hybrids, rice is an excellent model crop system for heterosis …

Background Heterosis is a phenomenon that hybrids show superior performance over their
parents. The successful utilization of heterosis has greatly improved rice productivity, but the …

Abstract Key message Heterosis QTLs, including qSS7 and qHD8, with dominance effects
were identified through GBS and large-scale phenotyping of CSSLs and hybrid F 1 …

Heterosis is a biological phenomenon whereby the offspring from two parents show
improved and superior performance than either inbred parental lines. Hybrid rice is one of …

Heterosis, which describes the superior vigor and yield of F 1 hybrids with respect to their
parents, is observed in many rice hybrid crosses. The exploitation of heterosis is a great leap …

The wide adoption of hybrid rice has greatly increased rice yield in the last several decades.
The utilization of heterosis facilitated by male sterility has been a common strategy for hybrid …
