Drought and low nitrogen are the most common abiotic stresses limiting rice productivity in the rainfed rice areas of Asia and Africa. Development and adoption of green super rice (GSR) varieties with greatly improved drought tolerance (DT) and low nitrogen tolerance (LNT) are the most efficient way to resolve this problem. In this study, using three sets of trait-specific introgression lines (...

Asian soybean rust (ASR) causes large reductions in yield, affecting the entire grain market. With low fungicide efficiency, use of resistant cultivars can be an economical, safe, efficient, and sustainable control alternative. However, great variability aggressiveness ASR Rpp genes are limited. Thus, gene pyramiding is a promising strategy for development with high resistance to greater number...

Successful management of plant diseases is mainly dependent on the accurate and efficient detection of plant pathogens, amount of genetic and pathogenic variability present in a pathogen population, development of disease resistant cultivars and deployment of effective resistance genes in different epidemiological regions. Beside conventional methods of pathogen detection and breeding resistant...

The most effective control of Bean common mosaic virus (BCMV) and necrosis (BCMNV) is achieved by using the seeds resistant cultivars. During conventional breeding, resistance against BCMV BCMNV in bean can be developed pyramiding strain-nonspecific dominant I gene with strain-specific recessive (bc-) genes for long-term control. In this study, a total 58 genotypes involving registered green dr...

French bean is one of the most important staple foods in many parts world. Among several bacterial, fungal and viral diseases, anthracnose caused by Colletotrichum lindemuthianum widespread severe disease bean. Therefore, present study was undertaken as prebreeding effort with objective introgression resistance gene Co-4 elite cultivar. Hybridization between resistant genotype, TO having cultiv...

Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...

Abstract Background Seed-set density is an important agronomic trait in rice. However, its genetic mechanism complex. Chromosome segment substitution lines (CSSLs) are ideal materials for studying complex traits. Results A rice CSSL, Z749, with a dense and erect panicle phenotype, was identified among progeny of the recipient parent Nipponbare donor Xihui 18. Z749 carried seven segments (averag...

Viral diseases caused severe damage for plant growth and development. Penetration spread of viruses in the host plants dramatically reduce crop yield quality. Due to critical damages viral agricultural production, different approaches methods have been developed utilized manage, protect improve virus resistance. Of which, conventional such as meristem culture, thermotherapy, cryotherapy well ch...
