‘Premier Russet’ has a late vine maturity and ‘Rio Grande Russet’ has a medium late maturity. 0–6.5) than ‘Premier Russet’ (6.0–7.5). For the progeny, mean trait values displayed a wide range of phenotypic variation (Additional file 4: Table S3), with a high correlation between years (> 0.70, P < 0.001) and across environments (> 0.55, P < 0.001). The broad-sense heritability for both years at each location was statistically significant, with H 2 estimates ranging from 0.83 to 0.93 (Table 2). These results were consistent for all vine maturity traits. When mean values for maturity were mapped to the linkage maps, a significant association was detected on chromosome 5 (Fig. 2, Additional file 6: Figure S2). This association was consistent between years and environments. Logarithm of the odds (LOD) scores ranged from of 21.2 and 34.1, well above the permutation thresholds. Collectively, they explained between 38 and 54% of the trait variance (Table 3). The peak of the LOD profile was consistently detected at 15.0 cM (Table 3, Fig. 2). The best simple model for maturity was a double-simplex configuration (AAAB ? AAAB) on homologous chromosomes H2 and H8 of Rio Grande russet (RGR) and Premier Russet (PR), respectively (Additional file 6: Figure S2). This model implies a QTL with allele effects from both parents, and with the B allele associated with earlier maturity (P < 0.001). Thus, progeny with two copies of the B allele (AABB) had on average earlier maturity (3.1–4.0) than progeny with a single copy (AAAB, 4.5–6.2) or lacking the B allele (AAAA, 6.4–7.5).

LOD threshold 95% count on times try listed in Dining table 3.

New SNP nearest on the QTL having readiness that had a double-simplex setup are solcap_snp_c2_11605, found at nine.step 1 cM. Regression of your own readiness imply opinions towards genotype on the SNP told me between 38 and fifty% of phenotypic variance. The fresh new level of your own LOD bend (fifteen cM) are organized within a space anywhere between markers one spanned 8 so you can 10 cM, towards solcap_snp_c2_11605 found on you to section of the gap. This area ports new Solanum tuberosum cycling DOF basis gene 1 (StCDF1, PGSC0003DMG400018408), that was considered to be a major regulator out-of potato plant readiness .
