Improving panicle blast resistance and fragrance in a high-quality <i>japonica</i> rice variety through breeding.

ABSTRACT:

Introduction

Huruan1212 (HR1212) is well-regarded for its superior eating and cooking quality in the lower reaches of the Yangtze River in China. Still, its high susceptibility to rice panicle blast and lack of fragrance have limited its further spread and utilization. Pigm and Pi-ta are two dominant genes known for their stable broad-spectrum resistance against rice blast fungus Magnaporthe oryzae, while badh2 is the crucial gene that regulates rice aroma.

Methods

In this study, we utilized a molecular marker-assisted selection backcrossing strategy to introduce Pigm, Pi-ta, and badh2 into introgressed lines employing re-sequencing for precise genetic background selection.

Results

Finally, we selected three introgresse
