Nature and inheritance of nematode resistance in cereals.
نویسنده
چکیده
Resistance to a number of nematodes is present in varieties of temperate and tropical cereals. The occurrence, nature, and inheritance of varietal resistance in cereals is reviewed. Evaluation of the practical significance of nematode resistance in a particular host-nematode combination is discussed in relation to host efficiency, host sensitivity, genetic control of resistance, and presence of virulence in the nematode population.

Breeding plants for resistance to nematodes.
Plant breeders and nematologists have developed improved cultivars of important crop species with resistance to plant-parasitic nematodes. The effectiveness of these breeding efforts has depended on the availability of efficient screening procedures, identification of adequate sources of durable resistance, nature of the nematode feeding habit, and knowledge of the inheritance of resistance. Th...
متن کاملThe Effect of Drought Stresses, Fusarium Culmorum and Heterodera Filipjevi and their Interactions on the Expression Pattern of Transcription Factor Gene NAC69-3 in Bread Wheat
SExtended Abstract Introduction and Objective: Small grain cereals such as wheat, are affected by types of destructive environmental factors such as abiotic and biotic stresses that severely reduce crop yields. To cope with these conditions, transcription factors cause plant resistance to these stresses by activating or suppressing the expression of genes involved in the resistance responses....
متن کاملانتقال ژنهای OF2 و VAP به چغندر قند با کمک آگروباکتریوم ریزوژنز برای بررسی مقاومت به نماتد
OF2 and VAP genes, probably involved in signal transduction of sugarbeet nematode resistance, have already been cloned in bacterial vector by AFLP molecular marker and a two-hybrid system, respectively. To examine their capability to introduce resistance in sugarbeet, the genes were transferred to plant expression vectors. For this reason, OF2 gene after isolation was inserted within T-DNA of p...

متن کاملEvaluation of the Resistance of Some Indigenous Wheat Genotypes to Cereal Cyst Nematode, Heterodera Filipjevi
Cereal cyst nematode (CCN) is one of the most deleterious pathogens of cereal crops worldwide including Iran. The species Heterodera filipjevi is widely distributed in the fields of wheat. Growing the resistant cultivars is a suitable environmental friendly and cost-saving procedure for nematode control. In current research, the resistance of 13 indigenous wheat genotypes and seven common ...
