Evaluate the QTL understood contained in this data having prior to now published P. striiformis f. tritici opposition genetics and QTL, also to receive real ranking, the fresh new source sequence and you will marker alignments regarding polymorphic SNP indicators and you can the fresh new SNP probes was aimed on the Chinese Spring season series by way of a-blast browse (IWGSC RefSeq v1.0; CS genome hereafter). Brand new SNP probes was basically as well as blasted contrary to the Svevo genome sequences within GrainGenes Svevo Genome Internet browser (Durum Grain Svevo RefSeq Rel. step one.0; durum genome hereafter).
Seedling tests with plants of susceptible and resistant RILs and of Svevo inoculated at different stages with the Israeli race (38E134) showed that plants were susceptible before the four-leaf stage but plants at the five-leaf stage began to show stripe rust resistance. Svevo at the five-leaf stage had IT 3 to 4, which was much lower than the IT of the most resistant RIL (Fig. 1A). To determine the broadness of the resistance in Svevo, six P. striiformis f. tritici races were used to inoculate Svevo together with susceptible control cultivars Zavitan, Falchetto, and MX169. The results showed that Svevo was susceptible (IT 8 to 9) to all six races (one from Israel and five from China) in the seedling tests but highly resistant (IT 1) in the adult-plant tests to all races. The susceptible parent, Zavitan, and MX169 and Falchetto were susceptible (IT 8 to 9) at both growth stages. Svevo had consistent IT 1 in the adult-plant stage under field conditions, whereas Zavitan, MX169, and Falchetto displayed IT 9 in all environments with a severity of 90 to 100% (Fig. 1B). The IT and DS values of the 137 RILs were in the range of 0 to 9 and 0 to 100%, respectively, indicating that resistance was quantitatively inherited (Fig. 2). In general, the ITs in Israel were higher for most of the lines than the ITs in China (Fig. 3). The broad-sense heritability of IT and DS was 0.91 and 0.92, respectively. Correlation coefficients (r) between IT and DS varied greatly between the 11 environments (r = 0.36 to 0.98) (Supplementary Table S1). The correlation coefficients were higher between the environments in China or in Israel but lower between environments in the two countries. In the pairwise comparison of the IT or DS, the values of r were all significant (P < 0.001) (Table 1), although the values of r between years were slightly lower than that within years. The ANOVA results based on both the IT and DS data showed that the interactions among the RILs, environments, and line–environment were significant (P < 0.01) (Table 2). No significant variation was detected among replications within each experiment, and the lines were the main source of high-heritability phenotypic variation.
