Molecular breeding for resistance to rhizomania in sugar beets
Lennefors, B-L. 2006. Molecular breeding for resistance to rhizomania in sugar beets. Doctor’s dissertation ISSN: 1652-6880, ISBN: 91-576-7255-5 Rhizomania is one of the most destructive sugar beet diseases. It is caused by Beet necrotic yellow vein virus (BNYVV) vectored by the soilborne protoctist Polymyxa betae Keskin. The studies in this thesis evaluated natural and transgenic resistances t...
متن کاملidentification of tetraploid pollinator resistant to leaf spot disease and bolting in sugar beet
to determine tetraploid pollinators resistant to cercospora leaf spot disease and bolting with optimum yield and quality, five tetraploid pollinators were crossed with a male sterile line, sb17. the hybrid seed was harvested from the male-sterile line. the hybrids together with four controls including resistant and susceptible cultivars (a total of 9 cultivars), were evaluated in a randomized c...

این تحقیق به منظور بررسی رابطه بین میزان استراتژیهای خود-تنظیم شده یادگیری و تمایل به ایجاد ارتباط دانشجویان زبان انگلیسی انجام شده است.علاوه بر این،روابط و کنش های موجود بین ریزسنجه های استراتژیهای خود-تنظیم شده یادگُیری ، مهارت نگارش و تمایل به برقراری ارتباط و همچنین تاٍثیرجنسیت دانشجویان زبان انگلیسی در استراتژیهای خود-تنظیم شده یادگیری و تمایل به برقراری ارتباط آنها مورد بررسی قرار گرفته شد.
15 صفحه اولPlasticity of leaf anatomy, chemistry and water economy of irrigated sugar beets grown under Mediterranean conditions
In a three-year (2004-2006), field experiment, we aimed to study changes in leaf physiological traits (leaf water potential-Ψleaf, leaf water content-LWC, carbon isotope discrimination-Δ, specific leaf area-SLA, chlorophyll content as assessed by SPAD and modified SPAD-MSPAD) and elemental composition (K, Na, Ca, Mg, K/Na, Ca/Mg, total leaf salinity-TLS) of sugar beets (cv. Rizor) grown unde...
متن کاملevaluation of commercial sugar beet cultivars for resistance to cercospora leaf spot under field condition
resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with 6 replications, and, disease severity of cultivars was measured two times. root yield of cultivars, as well as their disease severity, was compared with each other under natural cercospora infection in dezful area (winter crop). in dezful...
