Abstract

Onion is the one of most economically important vegetables in the genus Allium. In Japan, onion cultivars are mainly divided into two groups: spring-sowing (late-maturing) cultivars and autumn-sowing (early-maturing) ones.
As for the indices of the earliness in onion, we evaluated total leaf numbers (LN) and days to lodging (DL) from transplanting using an F₂ population between two onion cultivars under spring-sown cultivation in 2019. We also investigated plant height at harvest time and bulb traits at two months after harvest.
The correlation coefficient between LN and DL was 0.45. Both LN and DL were highly correlated to bulb weight and bulb diameter, whereas dry matter and number of centers were highly correlated only with DL. Genetic map consisted of 282 markers (224 amplicon sequence markers, 57 Indel and CAPS markers, and an Ms-linked markers) and was covering 871 cM. QTLs were detected on Chr2 (LN, LOD peak 7.7) and Chr4 (DL, LOD peak 3.7). QTLs for other traits were also detected on each chromosome.
In our previous study, year-to-year correlation in LN is higher than that of DL, we attempted to validate effect of LN QTL. Three F₂ individuals whose genotype was heterozygous at LN QTL-linked marker were selected and obtained F₃ lines by selfing.
Some F₃ individuals derived from single F₂ showed severe inbreeding depression, we excluded this line from further analysis.
In the other two lines, F₃ individuals having early-maturing cultivar-allele significantly decreased in LN. Thus, the LN QTL is effective for the breeding of earliness in onion.
