Description
Zhening Miao and eight colleagues report a 2026 genetic survey of water-saving, drought-resistant rice lines. Such rice matters where water is scarce. Two diseases, blast and bacterial blight, threaten its yields. The team genotyped 47 core parent lines for eleven blast resistance genes and four blight resistance genes.
One blast gene, Ptr, appeared in nearly every line. Broad-acting genes such as Pigm were absent, and Pi9 was uncommon. Blight resistance genes showed up in only about a third of lines, mostly in restorer lines. The recessive gene xa5 was missing entirely. More resistance genes generally meant stronger disease scores in the tests. The authors offer the map as a guide for choosing parents and stacking genes in breeding.
