Map design

Various thresholds were used to check abnormal bases, filter markers with designated missing values (20%), and discard any markers with distorted segregation (p < 0.001 in Chi-square test). Twelve seedlings of mapping population were excluded because they exhibited several double-recombination events. Using a final mapping population of 350 seedlings, we constructed an integrated map consisting of 10,172 markers and spanning cM. This included 4421 lm ? ll-type markers, 4688 nn ? np-type ong these, 5351 (4421 lm ? ll plus 930 hk ? hk) constituted linkage groups on the HC map with a total genetic distance of cM and 0.34 cM per marker, as well as 5623 (4688 nn ? np plus 935 hk ? hk) constituted linkage groups on the QG map with a total genetic distance of cM and 0.30 cM per marker (Table 3; Additional file 2: Figure S1; Additional file 3: Table S2).

I calculated brand new ? thirteen C from one or two mother cultivars and you will the progenies for 2 watering solutions within the 2014 and you may 2015 (Desk 4). The fresh ? 13 C are constantly lower getting HC compared to QG, showing that drought-tolerant characteristic got a robust genetic parts. Moreover, the range inside the version for ? 13 C throughout the segregating inhabitants usually exceeded the new phenotypic opinions of moms and dads, recommending you to definitely transgressive genetics try carried on and you will wasn’t influenced by sometimes cures otherwise 12 months. For all examples- parents and you will progenies-brand new induction regarding drought worry got a robust influence on ? thirteen C….
