Searching for wheat resistance to aphids and wheat bulb fly in the historical Watkins and Gediflux wheat collections.: Wheat resistance to aphids and wheat bulb fly
Insect pests can reduce wheat yield by direct feeding and transmission of plant viruses. Here we report results from laboratory and field phenotyping studies on a wide range of wheat, including landraces from the Watkins collection deriving from before the green revolution, more modern cultivars from the Gediflux collection (north-western Europe) and modern UK Elite varieties, for resistance to...

متن کاملDissipation and harvest time residue of 2,4-D in soil and wheat crop
Wheat, a member of family Poaceae is one of the major food crops in the world. Globally, it occupies about 17% of the cropped land and contributes 35% of the staple food (Pingali 1999).Wheat constitutes one of the most abundant sources of energy and protein for the world population and its increased production is essential for food security (Chhokar et al. 2006). Severe competition from weeds i...
متن کاملEffects of Wheat-Maize Intercropping on Population Dynamics of Wheat Aphids and Their Natural Enemies
To study the effects of wheat-maize intercropping on the population dynamics of wheat aphids and their natural enemies, wheat-maize intercropping patterns were divided into four levels: 8:2, 6:2, and 4:2 intercropping, and monoculture wheat. The results showed that as the wheat coverage rate decreased, the quantities of immigrating winged aphids and their natural enemies significantly differed;...
متن کاملExpression of Pinellia pedatisecta Lectin Gene in Transgenic Wheat Enhances Resistance to Wheat Aphids.
Wheat aphids are major pests during the seed filling stage of wheat. Plant lectins are toxic to sap-sucking pests such as wheat aphids. In this study, Pinellia pedatisecta agglutinin (ppa), a gene encoding mannose binding lectin, was cloned, and it shared 92.69% nucleotide similarity and 94% amino acid similarity with Pinellia ternata agglutinin (pta). The ppa gene, driven by the constitutive a...
