Abstract: Succinate dehydrogenase inhibitors (SDHI) are EU crop protection active substances which are controversial regarding their toxicity and ecotoxicity. From the total number of SDHI fungicides known (24) up to twelve were approved at EU plant protection Regulation EC 1107/2009 between 2011 and 2016. All these active substances are listed in Part A, B and E of Regulation EU 540/2011. Two SDHI approvals were removed by end of approval in 2021 and withdrawal in 2022 and there are concerns that more may follow in 2023. The evolution of these substances and the corresponding global modifications in terms of employment, functions, uses, crops and maximum residue limits were analysed in this work.

Abstract: Single nucleotide polymorphisms (SNPs) describe a change in a single nucleotide within the genome. SNPs are known as the markers of choice due to their desirable properties such as co-dominant in nature, robust, widely distributed throughout the genome, highly multiplexable, easily automated with high throughput techniques, have high reproduc- ibility, and high efficiency for detection of polymorphism. Several studies have been successfully performed for the iden- tifications of the functional SNPs in the plant crops. However, the effects of the identified functional SNPs on plant phe- notypes are not yet reviewed so far.

Abstract: Pumpkins (Cucurbita pepo) are valuable sources of nutrients for human consumption and have a capacity to enhance food security. However, their potential in Uganda has not been fully developed. There is limited information on pumpkin diversity in Uganda. This study, therefore, evaluated the diversity of pumpkins in Uganda using sequence repeats molecular and morphological markers. Correlation of morphology and genetic data was also evaluated.

Abstract: Maize is one of a major crop in Ethiopia in production, consumption and income generation for both resource constrained men and women. Although, productivity of maize in Ethiopia is showing increment in recent years however productivity in Eastern Hararghe is still low 24.06 qt/ha compared to the national and regional average. The experiment was conducted at high-land areas of East Hararghe namely Kurfa chele and Meta districts in 2018/19 and 2019/20 cropping seasons. The study was done with the objectives of to evaluate the performance of hybrid maize varieties for their adaptability, stability, high yielder and to recommend variety/ies for the study areas and similar agro-ecologies.

Abstract: Cowpea is a legume widely cultivated across the world but its growth may be limited by contamination with nonessential elements among which are arsenic. The present study was designed to examine the effect of salicylic acid on physicochemical parameters and accumulation of compatible solutes in cowpea under arsenic stress.

Abstract: Soil salinization is one of the major constraints in achieving food security and environmental degradation in Ethiopia. Restoration of salt-affected lands into productive lands and protection of newly developed areas from the spread of salinity is therefore of paramount importance.
