Molecular analysis of sorghum resistance to the greenbug (Homoptera: Aphididae).
Chromosomal regions of sorghum, Sorghum bicolor (L.) Moench, conferring resistance to greenbug, Schizaphis graminum (Rondani), biotypes C, E, I, and K from four resistance sources were evaluated by restriction fragment-length polymorphism (RFLP) analysis. At least nine loci, dispersed on eight linkage groups, were implicated in affecting sorghum resistance to greenbug. The nine loci were named ...
متن کاملNew Sources of Resistance to Greenbug in Barley
greenbug isolate avirulent to Wintermalt. Subsequent work by Ogecha et al. (1992) confirmed that biotype G Most biotypes of the greenbug [Schizaphis graminum (Rondani)] was less successful in feeding on Wintermalt compared are extremely damaging to barley (Hordeum vulgare L.). However, with other biotypes. When compared with biotypes E greenbug biotype G has been reported to be unable to succes...
متن کاملHyperspectral Field Spectrometry for Estimating Greenbug (homoptera: Aphididae) Damage in Wheat
Remote sensing techniques have the potential to provide information about vegetation characteristics. Therefore, this study was designed to determine the ability of a hyperspectral field spectrometer along with a digital camera to estimate greenbug (Schizaphis graminum Rondani) damage to wheat (Triticum aestivum L.) in field condition. Percentage reflectance data and digital images were collect...
