The value of delta K in structure analysis from K = 1 to K = 10 based on (A) DPRK germplasm, (B) Mini-Rice Diversity Panel and (C) combined DPRK germplasm and Mini-Rice Diversity Panel. Figure S2.
Table 9 presents the estimated number of people in need of food assistance requirements for 2011/2012, based on the DPRK 2008 population census.
Fifty one nSSRs were used for population structure analysis and to build a dendrogram based on the 80 DPRK accessions and the two South Korean elite varieties.
Figure 4 Dendrogram based on genetic similarity within DPRK varieties using nSSRs (A) and cpSSRs (B).
The analysis of genetic distance based on chloroplast SSRs (cpSSR) among DPRK accessions showed results consistent with the chloroplast haplotype network; the five DPRK accessions carrying the indica/aus-haplotype (as defined in Figure 3) were clearly separated from the accessions carrying the japonica-haplotypes.
When chloroplast haplotype data were used to compare groups based on pairwise Fst, the two DPRK groups did not significantly differ from one another (Table 1C) or from the temperate japonica group in the Mini-Rice Diversity Panel.
An UPGMA dendrogram, the useful method for narrow genetic distanced accessions, was constructed to determine the genetic relationships among DPRK accessions based on dissimilarity matrix using PowerMarker V3.23 and visualized in Mega5 (Sneath and Sokal [1973]; Tamura et al. [2011]).
Five haplotypes were detected in DPRK rice germplasm based on sequence analysis of 4,131 bp of the chloroplast.
Normal year seed requirement of 243 000 tonnes, based on the seed rates used in DPRK and the intended area to be sown in 2011/12, as shown in Table 7. 1/ Total includes seed for sloping lands and household gardens about 15 000 t. Post-harvest losses of 15percentt for rice, maize and potatoes, 10percentt for wheat, barley and other cereals and 5percentt for soybeans are assumed.
DPRK varieties showed greater cold tolerance based on PSS and phenotype acceptability at tillering (PAT) than other temperate japonica varieties, but inferior cold tolerance in SPP. Other traits, such as leaf discoloration (LDS), difference in DTH (D_DTH), reduction ratio of CL (R_CL), and panicle neck exertion (PE) were similar across the range of temperate japonica varieties.
