Sugarbeet (Beta vulgaris L.) germplasms FC716 through FC719 (Reg. no. GP-143 to GP-146, P1 574627 to P1574630) were developed by the USD A-ARS in cooperation with the Beet Sugar Development Foundation. Each of these germplasms was developed from genetically different and distinctive sources. These lines should provide resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kilhn and p...
Diseases of soybean caused by Cercospora spp. are endemic throughout the world's soybean production regions.

Currently, only two species (Cercospora kikuchii and C. sojina) are recognized to infect soybean; C. kikuchii causes Cercospora leaf ...
تجزیه ژنتیکی مقاومت به عامل بیماری لکه برگی با استفاده از روش تلاقی دیآللکراس در شش رگه منوژرم دیپلوئید چغندرقند انجام گرفت. والدین و 15 هیبرید نسل اول (F1 ) در قالب یک طرح بلوکﻫای کامل تصادفی با چهار تکرار در مرکز تحقیقات کشاورزی صفی آباد - دزفول مورد ارزیابی قرار گرفتند. کرتها پس از آلودگی یکنواخت به عامل بیماری، بر اساس معیار، یک (بسیار مقاوم ) تا پنج (بسیار حساس) رتبهبندی شدند. تجزیه د...
The genus Mycosphaerella Johanson, contains more than 3000 names (Aptroot 2006), and has been linked to more than 30 well-known anamorphic genera (Crous 2006a and 2006b). It has a worldwide distribution from tropical and subtropical to warm and cool regions (Crous 1998; Crous et al. 2000 and 2001). Mycosphaerella, however, has been associated with at least 27 different coelomycete or hyphomycet...
Fungi associated with leaf spot symptoms of plants in forest areas of Golestan province, Iran, were collected and examined based on morphological characteristics of conidiophores, conidia and conidiogenous loci. Ten taxa were identified. Among the taxa, Passalora cf. bacilligera and Pseudocladosporium hachijoens are new records for the mycobiota of Iran. Cercospora on Eruca sp. was morphologica...
