Salt stress is a major constraint across large rice production areas in Asia, because of the high sensitivity of modern rice varieties. To identify quantitative trait loci (QTL) associated with salt tolerance in rice, we developed an F2 population from a cross between the salt-tolerant landrace, Kalarata, and the salt-sensitive parent, Azucena. F3 ...

Brazil stands out worldwide in the production of coffee. The observed increases in its productivity and morpho agronomic traits are the results of the improvement of several methodologies applied in obtaining improved cultivars, among which the predictive methods of genetic value stand out. These contribute significantly to the selection of higher ...

Acerola (Malpighia emarginata DC.) is one of the most important fruit produced in the São Francisco Valley, a Semi-arid region in the Northeast of Brazil. This study aimed to evaluate the physicochemical quality of thirty-five acerola genotypes produced during two growing seasons in a Semi-arid region and to identify the best ones with potential fo...

Leaf rust caused by Puccinia triticina Eriks. is the most prevalent wheat rust worldwide and occurs annually wherever wheat is grown. The most economical and environmentally friendly method to control this fungal disease is genetic resistance, which is achieved through deploying effective resistance genes. Tightly-linked molecular markers facilitat...

The genetic architectures of agronomic and yield-related traits are expected to involve multiple loci that are unlikely all to segregate for alternative alleles in a single biparental population. Therefore, the identification of quantitative trait loci (QTL) that are expressed in diverse genetic backgrounds of multiple bi-parental populations provi...

In black gram, yellow mosaic virus (YMV) disease is a serious problem causing severe yield reduction. In the present study, F2 and RIL Population (F4:5) of the cross IC436656 (YMV susceptible) x KKB14045 (YMV resistant) were evaluated for YMV resistance through bulked segregant analysis (BSA) using SSR markers. Out of 91 SSR markers studied, thirte...

In subtropical environments lodging occurs at all stages of the oat plant development, particularly after panicle extrusion, causing severe yield reduction. This study aimed to identify morphological, chemical, and anatomical characteristics of the stem associated with lodging resistance on oats, which may be used to identify and select resistant g...

Reproductive-stage drought-stress is a major production constraint in rainfed rice ecosystem. Emergence of marker-assisted breeding strategies for developing drought-tolerant rice varieties are being optimized through exploiting adaptive-traits for their increased contribution towards grain-yield under recurring-drought. Grain-yield is a complex-tr...

Pepper yellow leaf curl disease caused by begomoviruses has emerged as a major limitation to the cultivation of pepper (Capsicum spp.) production in a number of regions around the world. Although begomovirus resistance has been reported in several accessions, pepy-1 derived from BaPep-5 (C. annuum) is the only begomovirus resistance gene cloned to ...

The plants of summer squash, Cucurbita pepo, are monoecious, bearing their flowers in leaf axils. Plants of C. pepo subsp. pepo, which includes Cocozelle and Zucchini squash, bear one flower per leaf axil whilst plants of C. pepo subsp. texana, which includes Crookneck squash, differentiate two or more flower buds at nearly all leaf axils. This mul...
