Breeding of Plant Nematode Resistant Varieties

Plant nematodes cause serious economic losses and affect the quality of crop products. Plant resistance to nematodes is one of several essential components in nematode management required for efficient crop production. The development and utilization of nematode-resistant cultivars result in reduced yield losses, increased grower profits, and lower costs for food and fiber for consumers. Plant breeders and nematologists have jointly developed productive, nematode-resistant cultivars in many major crops. These cultivars are available throughout the world to assist in the management of many plant nematode species.

Lifeasible, as a leading global company, is committed to helping our customers achieve effective and successful research. We provide breeding of plant nematode-resistant varieties, including conventional breeding and genetic engineering modification. We always deliver reliable results and reports on time to our customers worldwide.

Conventional Breeding for Nematode Resistant Varieties

• Conventional breeding achieves it by crossing together plants with relevant characteristics and selecting the offspring with the desired combination of characteristics due to particular combinations of genes inherited from the two parents.
• Lifeasible provides resistance identification and screening of different germplasm resources, firstly, to discover rich genetic resources and broaden the genetic base of resistance, which is very important for breeding against nematodes and is also an important basis for breeding for disease resistance.
• After that, we provide breeding programs, mainly systematic breeding, radiation breeding, cross breeding, backcross breeding, etc. In addition, we offer conventional breeding for nematode-resistant varieties in many species of plants, such as soybeans, tomatoes, cucumbers, sweet potatoes, etc.

Genetic Engineering Modification for Nematode Resistant Varieties

• Biotechnology offers several benefits for nematode control in an integrated management strategy, such as reducing risks to the environment and human health, accessibility for food producers in the developing world, and the possibility of achieving durable, broad-spectrum nematode resistance.
• There are essentially three approaches for engineering resistance, transgenic expression of natural resistance genes in heterologous species, targeting and disruption of the nematode, and feeding site attenuation.
• We also provide genetic engineering modification for nematode-resistant varieties, including natural resistance genes, transgenic-based protease inhibitors, and RNAi-targeted resistance, to select resistant varieties. In addition, we also help our clients analyze the inheritance of resistance in plants, such as horizontal, race-nonspecific, and durable versus vertical, race-specific, and nondurable.

Lifeasible is always devoted to providing high-quality and satisfactory service to our customers. We provide our clients with direct access to our experts and promptly respond to their inquiries.
