Background High-yielding cultivars of rice (Oryza sativa L.) have been developed in Japan
from crosses between overseas indica and domestic japonica cultivars. Recently, next …

Molecular breeding approaches are of growing importance to crop improvement. However,
closely related cultivars generally used for crossing material lack sufficient known DNA …

The source-sink relationship determines the ultimate grain yield of rice. In this study, we
used a set of reciprocal introgression lines (ILs) derived from Xuishui09× IR2061 to map …

Background Rice is staple food for more than half of the world's population including two
billion Asians, who obtain 60-70% of their energy intake from rice and its derivatives. To …

Abstract Background Heilongjiang Province is a high-quality japonica rice cultivation area in
China. One in ten bowls of Chinese rice is produced here. Increasing yield is one of the …

Abstract Background Cultivated rice (Oryza sativa L.) is one of the staple food for over half of
the world's population. Thus, improvement of cultivated rice is important for the development …

Single nucleotide polymorphisms (SNPs) and insertions–deletions (InDels) are valuable
molecular markers for molecular breeding among genetically closely related cultivars. Rice …

Rice is an important cereal for human consumption. Identification of QTLs for important
agronomic traits with high resolution is essential to the identification of genes and marker …

We searched the genomes of eight rice cultivars (Oryza sativa L. ssp. japonica and ssp.
indica) and a wild rice accession (Oryza rufipogon Griffith) for nucleotide polymorphisms …

Background Rice is an important human staple food vulnerable to heavy metal
contamination leading to serious concerns. High yield with low heavy metal contamination is …
