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 کاملComparative Response to Sugarbeet and Fodder Beet to Heterodera schachtii.
Sugarbeet and fodder beet (Beta vulgaris L.) are being considered for fuel alcohol product ion (1,2). Sugarbeet is susceptible to Heterodera schachtii Schm., and yields are adversely affected (3). T h e effect of the nematode on fodder beet is not known. T h e objective of this study, therefore, was to compare certain aspects of the host-parasite relations of H. schachtii on sugarbeet and fodde...
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 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 کاملNuclear magnetic resonance: a tool for imaging belowground damage caused by Heterodera schachtii and Rhizoctonia solani on sugar beet
Belowground symptoms of sugar beet caused by the beet cyst nematode (BCN) Heterodera schachtii include the development of compensatory secondary roots and beet deformity, which, thus far, could only be assessed by destructively removing the entire root systems from the soil. Similarly, the symptoms of Rhizoctonia crown and root rot (RCRR) caused by infections of the soil-borne basidiomycete Rhi...
