Tetraploid potato (Solanum tuberosum L.) is a genetically complex, polysomic tetraploid (2n = 4x = 48), highly heterozygous crop, which makes genetic research and utilization of potato wild relatives in breeding difficult. Notwithstanding, the potato reference genome, transcriptome, resequencing, and single nucleotide polymorphism (SNP) genotyping analysis provide new means for increasing the understanding of potato genetics and cytogenetics. An alternative approach based on the use of haploids ...

Agriculture faces enormous challenges including the need to substantially increase productivity, reduce environmental footprint, and deliver renewable alternatives that are being addressed by developing new oil crops for the future. The efforts include domestication of Lepidium spp. using genomics-aided breeding as a cold hardy perennial high-yielding oil crop that provides substantial environmental benefits, expands the geography for oil crops, and improves farmers’ economy. In addition, geneti...

Field cress (Lepidium campestre L.), despite its potential as a sustainable alternative oilseed plant, has been underutilized, and no prior attempts to characterize the genome at the genetic or molecular cytogenetic level have been conducted. Genetic maps are the foundation for anchoring and orienting annotated genome assemblies and positional cloning of candidate genes. Our principal goal was to construct a genetic map using integrated approaches of genetic, comparative and cytogenetic map anal...

Abstract Phenotypic plasticity refers to changes expressed by a genotype across different environments and is one of the major means by which plants cope with environmental variability. Multi-fold differences in phenotypic plasticity have been noted across crops, with wild ancestors and landraces being more plastic than crops when under stress. Plasticity in response to abiotic stress adaptation, plant architecture, physio-reproductive and quality traits are multi-genic (QTL). Plasticity QTL (pQ...

Avocado crop in Tanzania is sparingly investigated regardless of being an important fruit commodity. This study was undertaken to explore the yield and the value chain of this crop in the country. Data were collected mainly by face-to-face interviews with 275 avocado farmers, 231 avocado traders and 16 key informants. Descriptive statistics, Chi-square test and one-way analysis of variance were used for data analysis. The average crop yield ranged from 76 to 124 kg plant−1 between regions. The a...

Native grasses constitute the most important source of feed for camelids, sheep and cattle in the highlands of Bolivia, where the genus Festuca is one of the major feed components. This study was carried out to investigate the nutritional value of 11 Festuca ecotypes from the highlands of Bolivia and two cultivars from Argentina (Festuca arundinacea Schreb. cv. ‘Taita’ and Festulolium). All ecotypes were grown in the same experimental field and their protein, ash, cellulose, moisture and micronu...

Introduction Abiotic stresses may account up to 71% yield reduction in crops (Boyer, 1982). In this regard, access and control to water resources are becoming among the most important issues of this 21st century. On-going climate change also influences water supply by affecting rainfall and evapo-transpiration. Today 450 million people are subject to severe water shortage and in 2025 this number may be about 2.7 billion (or 1/3 of world's population). Statistics show that in the USA insurance in...

The burdens of malnutrition, protein and micronutrient deficiency, and obesity cause enormous costs to society. Crop nutritional quality has been compromised by the emphasis on edible yield and through the loss of biodiversity due to the introduction of high-yielding, uniform cultivars. Heirloom crop cultivars are traditional cultivars that have been grown for a long time (>50 years), and that have a heritage that has been preserved by regional, ethnic, or family groups. Heirlooms are recognized...
