Adaptation to varied habitats confers ecological versatility and the capacity for coarse-grained distribution across heterogeneous habitats, whereas ecological specialization implies a restricted pattern. Ecogeography and adaptive trairs help to determine whether farmers are able to adjust their diverse erops to socioeeonomie and environmental changes (a process known as in situ conservation) o...

Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published sources for the period 1842-2016. A geographic...
در این بررسی، 30 نمونه (6 جمعیت) از گونههای بال بلند بخشه onobrychis از جنسmill. onobrychis شامل گونه های o. verae širj., o. gontscharovii vassilcz., o. ptychophylla širj. & rech. f., o. sosnovskyi grossh. و o. araxina schischkin، از زیستگاه های طبیعی خود در ایران جمع آوری شدند. این نمونهها با استفاده از 45 ویژگی کمی و 15 ویژگی کیفی مورفولوژیکی مورد ارزیابی قرار گرفتند. به منظور بررسی تن...
UNLABELLED PREMISE OF THE STUDY The taxonomy of cultivated potatoes has been highly controversial, with estimates of species numbers ranging from 3 to 17. Ploidy level has been one of the most important taxonomic characters to recognize cultivated potato species, containing diploid (2n = 2x = 24), triploid (2n = 3x = 36), tetraploid (2n = 4x = 48), and pentaploid (2n = 5x = 60) cultivars. We...
