Abstract
An increase in quantity as well as quality are the primary objectives
of rice breeding program. Conventional breeding is based of phenotypic
selection, time consuming, laborious and has a significant risk of linkage
drag. DNA molecular marker methods are faster, easier, and less costly than
traditional breeding operations. Marker-assisted selection (MAS) is becoming
popular because it improves plant breeding efficiency by precisely transferring
gene of interest and speeding up the recurrent parent genome's recovery. MAS is
used to target yield and agronomic features, cooking and nutritional
quality, and tolerance to biotic- abiotic stress. MAS is frequently used in
gene pyramiding for disease and pest resistance. Quality and productivity of
rice depends upon various genes that are directly or indirectly affect total
outcomes. Selection of genes associated with different traits, MAS contributed
to enhance food security and human health. As a model crop with a fully
sequenced genome, rice offers excellent chances to investigate the molecular
mechanisms of yield, biotic-abiotic stress improvement and to engineer the
creation of rice varieties with higher potential that are effective against
different types of stresses. In this review, we discussed about different QTLs
that helps in MAS for improving quality traits, agronomic traits, and
biotic/abiotic stresses of rice.
