Resistance Response of Drought and Heat Tolerant Spring Wheat Lines against the Cereal Cyst Nematode Heterodera filipjevi

Wheat (Triticum aestivum L.) is extremely affected by several abiotic and biotic stresses. Drought and/or heat alongside the parasitism of cereal cyst nematodes Heterodera genera can have a combined destructive impact on wheat. Solely, nematode species filipjevi cause wheat yield losses up to 50%. Several control measures been implemented, yet, most economical convenient strategy use resistant hosts. Therefore, main aim this study was evaluate response 257 spring lines obtained from CIMMYT that might contain novel sources resistance be added as genetic resources for future breeding programs. Also, provide base research understand relationship between resistances drought tolerance. The results indicated 11 (4%) 36 (14%) were moderately resistant, respectively. High frequency susceptible highly low within set also recorded. linear regression analysis number cysts formed grouping showed strong, positive, correlation. Log-linear there weak positive correlation tolerant their these tolerance, while negative lines. This able add new upcoming
