understanding of grain quality and attributes derived from
sensory evaluation to leverage integrative gene discov-
ery strategies that enable breeding programs to efficiently
tap the huge genetic diversity in rice for novel genes that
enhance rice food quality.
Introduction
Rice (Oryza sativa L.) belongs to the family Poaceae and
tribe Oryzeae. It has two cultivated species and 22 wild
species and possesses huge diversity for grain quality traits.
Market survey data suggest that efforts to develop varieties
with improved cooking and eating quality have high eco-
nomic returns (Son et al. 2014). Even though grain qual-
ity strongly drives the market value of rice (Dalton 2004),
varietal improvement programs have largely focused on
enhancing yield with a lag in focusing on grain quality.
Grain yield and key grain quality traits are complemen-
tary beneficial traits. However, breeding varieties with both
higher yield potential and superior grain quality traits have
not had much historical success (Peng et al. 2008). Low- to
moderate-yielding varieties that have the best organoleptic
Abstract
Key message The holistic understanding derived from
integrating grain quality and sensory research out-
comes in breeding high-quality rice in the light of post-
genomics resources has been synthesized.
Abstract Acceptance of new rice genotypes by producers
and consumers hinges not only on their potential for higher
yield but recent emphasis has also been on premium-value
genotypes that have the ability to satisfy consumer prefer-
ences for grain quality. This review article provides insights
into how to link grain quality attributes and sensory per-
ception to support breeding superior rice varieties. Recent
advances in quality profiling and omics technologies have
provided efficient approaches to identify the key genes
and biochemical markers involved in rice quality traits.
Emphasis has been given to the upcoming area of holistic
