Nitrogen deficiency is a limiting factor in increasing efficiency of crop production in terrestrial ecosystems, and the transformation of inert nitrogen to forms that can be assimilated by plants is mediated by soil microorganisms. Symbiotic nitrogen-fixi... see more

The results of the study of drought tolerance of isogenic (NILs – near isogenic lines) by genes PPD (photoperiod) wheat lines and isogenic by genes ?? (early maturation) soybean lines, that control the photoperiodic sensitivity are presented. In field exp... see more

Soybean (Glycine max (L.) Merr.) is a typical short-day and thermophilic crop. Absence of or low sensitivity to photoperiod is necessary for short-day crops to adapt to high latitudes. Photoperiod insensitivity in soybeans is controlled by two genetic sys... see more

Marker assisted back crossing (MABC) is a molecular tool that can help breeders in reducing backcrossed generation. However, effectiveness of this method still needs further approval using actual phenotypic performances. The International Rice Research In... see more

Two pot experiments were conducted using elite lines and near isogenic lines (NILs) of winter wheat in a controlled environment to evaluate the effect of time of inoculation and subsequent increase in temperature during grain-filling on Fusarium head blig... see more

Stripe rust (yellow rust), caused by Puccinia striiformis f.sp. tritici (Pst), is a serious disease of wheat worldwide. Growing resistant cultivars is the most cost-effective and environmentally friendly approach to control the disease. Fifteen Egyptian w... see more

Two types of floods can be happen in rice crops, i.e. flash floods and  stagnant floods. Flash floods cause complete submergence for up to 2 weeks, while stagnant floods (SF) could partially submerge part of rice  plant. To overcome yield loss d... see more

The near-isogenic tomato cultivars Motelle (bearing the Mi-gene for resistance to Meloidogyne spp.) and Moneymaker (susceptible) were inoculated with 16 Meloidogyne populations. An average reproduction index for each population was obtained from a series ... see more
