An important problem in organic carrot production in the Netherlands is the occurrence of black spots during storage. Several different fungal pathogens cause similar symptoms, which are collectively known as black spot diseases. We identified Alternaria radicina, A. dauci and Rhexocercosporidium carotae (syn. Acrothecium carotae) as the most prevalent black spot pathogens. We developed laborat...

A local variety or landrace is a dynamic and ancient population of a cultivated crop, characterised by a well-established historical and geographical identity, which is locally adapted to the natural resources, agronomic p ractices of farmers and cultural traditions of consumers (1). Within the last few decades, interest in local varieties has been renewed primarily because of the rediscovery o...

Apple is one of the intensive grown and widely cultivated fruit crop in the temperate region, around the world. China, USA, Iran, India and Italy are the highest apple producing countries in the world. More than 60% of world apple productions come from these countries. More than 7.500 apple cultivars are grown around the world. Generally most popular apple varieties in the world are pink lady, ...

Approaches to soil management, including problems of soil degradation and low soil fertility, have recently undergone major changes. The former view was to concentrate on achieving high levels of production from the more fertile areas, leaving the marginal lands for extensive use only. Steeply sloping and highly drought-prone areas were preferably not to be cultivated at all. Soil constraints w...

Chrysanthemum is one of the ornamental plants that cultivated widely in worldwide. This flower is one of the most important cut and pot flowers in the world due to its high diversity of colors and shapes. The creation of mutation is an important method for the production of new cultivars, and many cultivars have been produced through spontaneous and induced mutations. In this study, explants of...

Pomegranate (Punica granatum L.) is a multipurpose plant that is important as nutrition, medical, horticulture, landscape and environment. The plant has been cultivated since old Iran and Egypt which is mentioned in Bible and Quran. Origin of the plant is Iran and some neighbour countries, although it is cultivated in many countries, now a day. Botanically, it is classified in Punicaceae and ha...

The genetic diversity of a large number of pistachio genotypes grown in Iran is not exactly known. Most of the studies on genetic diversity of Iranian pistachio varieties are based on morphological characteristics or isozyme markers. In the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by Amplified Fragment Length Polymorphism (...
