The establishment of stress resilient sugar beets (Beta vulgaris spp. vulgaris) is an important breeding goal since this cash crop is susceptible to drought and salinity. The genetic diversity in cultivated sugar beets is low and the beet wild relatives are useful genetic resources for tolerance traits. Three wild beet populations (Beta vulgaris spp. maritima) from contrasting environments, Vai...
the aim of this study was to investigate the effect of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named bp mashhad, bp karaj and 191. the experiment was in a split plot based on randomized complete block design , carried out at motahari research station of sugar beet seed research institute ...
to study the effect of powdery mildew on sugar beet yield and percentage of sugar losses sugar percent losses, ten genotypes were compared in a factorial experiment based on randomized complete block design with 3 replications and two factors. the first factor was spraying treatment with two levels and the second were genotypes. inoculation was carried out using the pathogens' conidial ...
Stability Analysis of Genotype × Environment Interaction Effect on Sugar Yield in Sugar Beet Hybrids
Testing plant varieties under different regions is necessary to assess their stability. In this study, 17 sugar beet genotypes were evaluated in a randomized complete block design with six replications in five regions including Karaj, Hamedan, Miandoab, Mashhad, and Shiraz. After checking the homogeneity of mean squares in five experiments by Bartlett’s test, analysis of the combined was per...
Remote sensing technology is widely used in environmental and agricultural research, and nowadays it has become a valuable and reliable source of information for the management of crop production and assessment of global supply and demands for these products. The objective of this study was to investigate the feasibility of using MODIS data and vegetation indices based on sugar beet growth moni...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
Reproduction of Heterodera schachtii Schmidt on Resistant Mustard, Radish, and Sugar Beet Cultivars.
The reproduction of a Wyoming population of Heterodera schachtii was determined for resistant trap crop radish (Raphanus sativus) and mustard (Sinapis alba) cultivars, and resistant and susceptible sugar beet (Beta vulgaris) cultivars in a greenhouse (21 degrees C/16 degrees C) and a growth chamber study (25 degrees C). Oil radish cultivars also were field tested in 2000 and 2001. In the greenh...
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...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
