A rice physiological disorder makes mature panicle keep erect with empty grains termed as “straighthead.” Straighthead causes yield losses and is a serious threat to rice production worldwide.
Here, a new study of association mapping was conducted to identify QTL involved in straighthead.
A subset of 380 accessions was selected from the USDA rice core collection and genotyped with 72 genome-wide SSR markers.
An optimal model implemented with principle components (PCs) was used in this association mapping.
As a result, five markers were identified to be significantly associated with straighthead.
Three of them, RM263, RM169, and RM224, were consistent with a previous study.
Three markers, RM475, RM263, and RM19, had a resistant allele associated with a decrease in straighthead rating (straighthead rating ≤ 4.8).
In contrast, the two other marker loci RM169 and RM224 had a few susceptible alleles associated with an increase in straighthead rating (straighthead rating ≥ 8.7).
Interestingly, RM475 is close to QTL “qSH-2” and “AsS” with straighthead resistance, which was reported in two studies on linkage mapping of straighthead.
This finding adds to previous work and is useful for further genetic study of straighthead.
