Sakha 101 is one such short grained common Egyptian rice cultivar and known for its exquisite quality, however, is highly susceptible to blast disease that has led to considerable decline in its area. Sakha 101 was crossed to a blast gene donor line, HR5824-B-3-2-3 and followed through backcross-breeding method that helped to incorporate blast resistance genes and finally Sakha 108 was released as improved version of the most widespread Egyptian commercial rice Sakha 101. The study was to evaluate Sakha 101 and Sakha 108 for high yielding, blast resistance, and effective resistance genes to Pyricularia oryzae as well as assessment of genetic divergence based on genomic in these cultivars. There is a slight increase in the values of Sakha 108 than Sakha 101 in the most of studied traits. Also under this study, seventy isolates were identified as eight main groups i.e., IA, IB, IC, ID, IF, IG, IH and II, but ID group was considered the most common races. On the other hand, Pi-Z and Pii - Pi-ks resistance genes were the most effective genes to blast fungus. Sakha 108 proved resistance for all tested isolates under greenhouse condition compared with Sakha 101 which exhibited susceptible to 70% of tested isolates. On genomic level, out of 242 markers across the 7 chromosomes; only 6 markers (RM8236, RM13611, RM3839, RM17377, RM160 and RM27154) produced clear fragments and polymorphism between cultivars (Sakha 101 and Sakha 108) and were used to construct a genetic linkage map. A total of 39 candidate genes were identified around their regions on each chromosome. These results enrich our understanding of the differences between Sakha 101 and Sakha 108 and also provide a foundation for selecting candidate for marker-assisted selection breeding in rice.
