An investigation was undertaken to study the feasibility of sugarbeet cultivation under Bangladesh condition during winter season of 2009-2010. Seeds of 14 sugarbeet genotypes were sown in the experimental field of Horticulture Research Centre of BARI, Gazipur on 10 November 2009. Visible root swelling in all genotypes started between 36 and 40 days after sowing (DAS). Nine genotypes had white ...

Improved root architecture is an effective strategy to increase crop yield. We demonstrate that overexpression of transcription factor gene MORE ROOT (TaMOR) from wheat (Triticum aestivum L.) results in more roots and higher grain yield in rice (Oryza sativa). TaMOR, encoding a plant-specific transcription factor belonging to the ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES (AS2/LOB) protein fam...

Hatamabadi-Farahani M. 2019. Root knot disease of pomegranate. Plant Pathology Science 8(1):38-49. DOI:10.2982/PPS.8.1.38.    Pomegranate is an important fruit crop which is attacked by several pests and pathogens. Diseases caused by nematodes are of economic importance. The root knot nematodes (Meloidogyne spp.) causing considerable yield losses in pomegranate.  Root knot nematodes are seden...

Knowledge on gene action and trait expression are important for effective breeding. The objective of this study was to determine the general combining ability (GCA), specific combining ability (SCA), maternal effects and heritability of drought tolerance, yield and yield components of candidate sweetpotato clones. Twelve genotypes selected for their high yield, dry matter content or drought tol...

Water supply in arid and semiarid regions of the world is a serious problem in crop production. Grafting may enhance water stress resistance and plants growth. In order to evaluate the effect of different cucurbit rootstocks (Flexifort, Shintoza and ungrafted cucumber) and water stress (40, 60, 90% of field capacity) on morphologic traits and yield of greenhouse cucumber (Cucumis sativus L. var...
