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...

Identification of Elite Rice (Oryza sativa L.) Lines with Durable Bacterial Blight Resistance through Phenotypic and Molecular Approaches
Bacterial leaf blight, caused by Xanthomonas oryzae pv. oryzae, is an important disease of rice that can substantially reduce crop performance under favourable disease conditions. The present study was conducted to identify elite rice lines resistant to bacterial leaf blight using phenotypic evaluation supported by mol...

Marker-assisted Pyramiding of Bacterial Blight Resistance Genes into ‘Uma’, an Elite Red Rice Variety of Kerala
Background: Uma is a high-yielding, popular red-kernelled rice variety of Kerala; however, the occurrence of BB disease often causes severe yield reductions in this cultivar. Host plant resistance based on multiple genes is the most effective measure to impart durable resistance. Hence, efforts were undertaken to intro...

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...

QTL mapping for leaf rust resistance in bread wheat using PBW343/W8627 RIL population
Introduction Leaf rust, caused by Puccinia triticina, inflicts 10-50% yield losses in bread wheat, with newly emerging virulent pathotypes overcoming major Lr genes and rendering the cultivars susceptible. The identification of genetic loci conferring resistance to wheat leaf rust, coupled with the development of molec...

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...
