Correlations among germination index (GI), germination resistance (GR) and percent germination (PG) measures at day 3, 5, 7, 10, 14 and 21 in SC8021-V2/AC Karma DH population evaluated across environments. Supplementary Table 2. Details of marker distribution and map length of the 24 linkage groups of the SC8021V2/AC Karma doubled haploid mapping population Supplementary Fig. 1a-c. Comparison of the (a) germination index, (b) germination resistance and (c) percent germination at day 3, 5, 7, 10, 14, 21 for whole seed among parents and checks tested in field and greenhouse environments where SC is Swift Current; SK, Saskatoon; GH, greenhouse Supplementary Fig. 2a-l. Frequency distribution for germination index, germination resistance and percent germination at day 3, 5, 7, 10, 14 and 21 in SC8021-V2/AC Karma doubled haploid mapping population along with their parents evaluated across environments. In each graph ‘S’ stands for SC8021-V2 and ‘A’ stands for AC Karma. In each graph, mean values of GI, GR and PG measures for both parents in Swift Current (S1, SC8021-V2; A1, AC Karma) and Saskatoon (S, SC8021-V2; A, AC Karma ) are indicated by arrows. The maximum standard error of the difference (SED) between parents and lines is reported
