Conventional Breeding for Nematode Resistant Varieties

Hundreds of new crop varieties are released every year by commercial conventional breeding to improve crop productivity, bolster food security, enhance nutrition, and expand consumer choice. The process of conventional breeding has evolved, creating an effective framework that not only improves crop performance but also supports the development of safe and nutritious foods. Plant breeding is a process of making decisions about which parents to choose, which parents to cross pollinate, and which progeny to advance.

Lifeasible offers comprehensive services covering a wide range of cutting-edge technologies to advance your projects. Our scientists have developed a series of innovative solutions to help clients with the conventional breed for nematode resistant varieties.

Breeding for Nematode Resistant Soybean Varieties

• Soybean cyst nematode (SCN) is a soil-borne sedentary endoparasite nematode and a devastating disease in soybean production worldwide. The application of resistant varieties to control SCN is the most cost-effective control measure. Therefore, research on soybean resistance to cyst nematodes has been one of the hot spots in soybean breeding for disease resistance worldwide.
• Lifeasible provides breeding for nematode resistant soybean varieties, including Identification of SCN-resistant physiological subspecies in soybean, screening of SCN-resistant resources, selection of SCN-resistant varieties, and application of SSR markers in soybean resistance cyst nematode research. In addition, we offer a characterization of newly selected varieties, yield performance analysis, and regional adaptation analysis.

Breeding for Nematode Resistant Cucumber Varieties

• Cucumber is one of the most sensitive crops to root-knot nematodes, and root-knot nematode damage is becoming increasingly serious in cultivation, resulting in a significant reduction in yield and quality. Selection and breeding of nematode resistant varieties are an effective way to solve this problem.
• We help our customers to screen breeding materials with nematode tolerance from domestic and foreign germplasm resources and breed new nematode resistant cucumber varieties, including parental selection, hybrid selection of varieties, tolerance tests to nematodes, and others.

Breeding for Nematode Resistant Tomato Varieties

• Tomato is one of the main varieties of facility vegetables and is a highly susceptible root-knot nematode vegetable crop. In recent years, with the continuous expansion of the protected area, the root-knot nematode damage to tomatoes has become increasingly serious, generally reducing yields by 20% to 30%.
• We provide nematode-resistant tomato variety selection services, including parental selection, hybrid combination trials, production trials, quality determination, and disease resistance evaluation.
