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...
متن کاملevaluation of different sugar beet populations for resistance to beet cyst nematode (heterodera schachtii schmidt(
in this research, 30 sugar beet breeding populations developed by crossing of sugar beet monogerm and multigerm male strile lines with nematode resistant wild sources (w-1009 contaning resistance gene from beta procumbens and w-1010 contaning resistance genes from beta maritima) were compared with resistant and susceptible checks with respect to nematode resistance and yield. the experiments we...
متن کاملThe composition of the cyst wall of the beet cyst-nematode Heterodera schachtii.
1. Cyst walls of the beet cyst-nematode (Heterodera schachtii Schmidt) were obtained by sieving a suspension of crushed cysts; about 15mg of dried cyst walls was obtained from 1000 cysts. 2. The cyst walls contained 68% protein calculated from nitrogen content. Glutamic acid, glycine, proline and hydroxyproline made up about 54% by weight of the amino acids obtained on acid hydrolysis. 3. Minor...
متن کاملEffect of short-term salinity on photosynthesis and ion relations in two sugar beet cultivars.
A factorial pot experiment was conducted based on randomized complete blocks design in green house condition to investigate the effect of short-term salt stress on leaf photosynthesis and ion relations of two sugar beet cultivars (Madison and 7233-P29). Plants were exposed to 0, 50, 150, 250, and 350 mM salinity (NaCl and CaCl2 in 5:1 molar ratio) for 48 hours. Measurements were done on younges...
متن کاملFUNGI ASSOCIATED WITH SUGAR BEET CYST NEMATODE FROM FIELDS OF W. AZERBAIJAN (I)
Fungi associated with sugar beet cyst nematode (Heterodera schachtii Schmidt) in W. Azerbaijan were isolated from different stages during 2002-2004 and studied. Some 300 fungal isolates were obtained. In this paper, 16 species belonging to nine genera are identified. Among them, three species viz. Lecanicillium aphanocladii, Myrothecium verrucaria andPlectosporium tabacinum are as new records t...
