Genetic Diversity for Resistance to Heterodera glycines Race 5 in Soybean.
Heterodera glycines is a serious pest of soybean in the United States. Plant introductions 90763 and 424595 are reported to be resistant to H. glycines race 5; however their genetic relationship for resistance is unknown. Crosses between these two lines and the susceptible cultivar Essex were studied in the F, F, and F generations to determine the number of genes involved in inheritance of resi...
متن کاملStructural Changes Associated with Resistance of Soybean to Heterodera glycines.
Subcellular responses to infection by Race 3 of Heterodera glycines in susceptible ('Lee') and resistant ('Forrest' and 'Bedford') soybean cultivars were compared. Syncytial formation, initiated in susceptible as well as resistant soybean cultivars, was characterized by wall perforations, dense cytoplasm, and increased endoplasmic reticulum, In susceptible plants, syncytia developed continuousl...
متن کاملAn Alternative Field Method for Screening Soybean Genotypes for Resistance to Heterodera glycines.
The soybean cyst nematode (Heterodera glycines) has become an increasingly severe problem in soybean production areas in Brazil. The development and use of resistant cultivars is the most efficient method of minimizing losses due to this pathogen. Our objective was to test the efficiency of an alternative method for screening soybean genotypes for resistance to H. glycines in field plots. The a...
متن کاملRNA-seq data comparisons of wild soybean genotypes in response to soybean cyst nematode (Heterodera glycines)
Soybean [Glycine max (L.) Merr.] is an important crop rich in vegetable protein and oil, and is a staple food for human and animals worldwide. However, soybean plants have been challenged by soybean cyst nematode (SCN, Heterodera glycines), one of the most damaging pests found in soybean fields. Applying SCN-resistant cultivars is the most efficient and environmentally friendly strategy to mana...
متن کاملGenetic Relationships for Resistance to Heterodera glycines Races 3 and 5 in Soybean.
Heterodera glycines is the most damaging root pathogen of soybean in the United States. Plant introduction (PI) 90.763 is resistant to both races 3 and 5, whereas PI 424.595 is resistant only to race 5. Genetic relationships in these PI lines for resistance to H. glycines are not known. Crosses between PI 90.763 and PI 424.595 and susceptible cv. Essex were studied in the F, F, and F generation...
