a total of 165 wheat landraces with their originated from northwest regions of iran were studied at research station of agricultural faculty, univ. of tabriz, using two experimental designs in two spring and fall growing seasons. during these experiments, growth habits of 104 wheat landraces were assessed and their representative seeds harvested in similar conditions. these landraces were analy...

Due to growing concern for the genetic erosion of local varieties, four of the main corn landraces historically grown in Veneto (Italy)—Sponcio, Marano, Biancoperla and Rosso Piave—were characterized in this work. A total of 197 phenotypically representative plants collected from field populations were genotyped at 10 SSR marker loci, which were regularly distributed across the 10 genetic linka...

The essential oil yield stability of damask rose (Rosa damascena Mill.) as an important medicinal and aromatic plant in different environments has not been well documented. In order to determine appropriate stability parameters, six statistics were studied for essential oil stability of 35 Rosa damascena landraces in seven locations (Sanandaj, Arak, Kashan, Dezful, Stahban, Ke...

Basil (Ocimum L.), a medicinal and aromatic plant genus, is widely used in food and pharmaceutical industry for ages. Our previous studies reported high potential of essential oils in the unexplored and un-exploited landraces of Omani basil. In the present study, nine Omani landraces of common basil (Ocimum basilicum L.) were analyzed for the assessment of genetic diversity with RAPD markers. O...

Fusarium wilt is one of the most destructive diseases of muskmelon (Cucumis melo L.), which is an economically important disease worldwide causes yield losses in muskmelon growing areas. One of the most effective controlling measures to prevent Fusarium wilt is through host resistance by using resistance genes. We used developed molecular markers for Fom-2 gene, which confers ...

Gene banks around the world hold over 370.000 accessions of barley (van Hintum and Menting, 2003). Although a large number of landraces and obsolete cultivars are stored in genebanks the geographic coverage of this conserved material is far from evenly distributed. For example only a handful of landraces from Northern Europe have been conserved (Jones et al, 2008a). Thus studies of geographic d...

Landraces of maize (Zea mays ssp. mays) and its wild teosinte relatives (Zea mays spp. parviglumis and mexicana) were surveyed for sensitivity to fumonisin B(1), a phytotoxin produced by the maize pathogen Gibberella moniliformis. Only two of 42 Z. mays samples were highly insensitive to FB(1) (ED(50) = ca. 200 microM). The teosintes and 76% of the maize landraces were moderately or highly sens...

to study the genetic relationships among iranian onion landraces and to compare them with those in some foreign cultivars, fifteen microsatellite (ssr) primer pairs were employed. based upon the results of the obtained band pattern, 12 pairs of ssr primers in 18 onion landraces and five foreign cultivars form a polymorphic and scorable pattern. there were two to six alleles with an average of 3...

Genetic diversity underlies the improvement of crops by plant breeding. Landraces of tomato (Solanum lycopersicum L.) can contain valuable alleles not common in modern germplasms. The aim was to measure genetic diversity present in 47 most common tomato varieties grown in Italy, 35 were varieties used for processing and 12 were landraces considered "salad varieties". Furthermore, we demonstrate...

Piper betle L., a dioecious shade-loving perennial climber is one of the important Pan-Asiatic plants. More than hundred landraces having marked variation in leaf chlorophyll (Chl) content are in cultivation in India. In this study, role of chlorophyllase (Chlase) in Chl homeostasis and post-harvest breakdown was investigated in two contrasting P. betle landraces Kapoori Vellaikodi (KV) with li...
