A successful stacking of multiple biotic stress resistance in rice facilitated by genes and precision breeding tools

Genetic improvement of rice for biotic stress is a major and continuous breeding objective owing to changing pest and disease scenarios. In response to climate change, an outbreak of new pathotypes and biotypes results in huge yield loss which directly impacts the economic stability and food security. The development o...

Agronomic Performance of Aromatic Rice (BC4F1) Derived from Inpari 33 × Merah Wangi Crosses

Background: Aromatic rice quality is primarily determined by loss-of-function mutations in the BADH2 gene, which lead to the accumulation of 2-acetyl-1-pyrroline (2AP). This study aimed to introgress the BADH2 aromatic allele from Merah Wangi into the high-yielding variety Inpari 33 and to evaluate the agronomic perfor...

Characterisation of advanced breeding lines for bacterial leaf blight resistance by morpho-molecular screening in rice (Oryza sativa L.)

Sixty advanced breeding lines of rice were evaluated for resistance to bacterial leaf blight (BLB) both phenotypically and genotypically at Regional Agricultural Research Station (RARS), Maruteru, Andhra Pradesh, India during kharif, 2023. Phenotypic screening was performed following the International Rice Research Ins...

Exploring the Diversity of Blast Resistance Genes in Rice Lines Using PCR-Based Functional STS Markers

Rice blast, caused by Pyricularia oryzae (syn. Magnaporthe oryzae), remains one of the most destructive diseases of rice worldwide. Developing resistant varieties is a sustainable strategy for disease management, and information on the diversity of blast resistance genes is important for selecting breeding parents. Thi...

Morphological and Molecular Screening for Bacterial Leaf Blight Resistance in Land Races of Rice (Oryza sativa L.)

Bacterial leaf blight (BLB) of rice, caused by Xanthomonas oryzae pv. oryzae, is a major constraint on rice production, and the use of resistant genotypes is an important approach to disease management. The present study screened 40 rice genotypes for BLB resistance using morphological evaluation and molecular markers...

Marker-Assisted Development of Rice Line G163 Combining Pi2-Mediated Blast Resistance, Xa7-Mediated Bacterial Blight Resistance, and Favorable Grain Quality

Rice blast and bacterial blight are two major diseases that threaten rice production worldwide. Developing rice cultivars with both disease resistance and desirable grain quality is an important objective in modern rice breeding. In this study, R1179 carrying Pi2, Wxb and Alkb was crossed with IRBB7 carrying Xa7, Wxb a...
