Relationships Between Tolerance and Resistance to Meloidogyne incognita in Cotton.
The southern root-knot nematode, Meloidogyne incognita, is the most damaging pathogen of cotton in the United States, and both resistance and tolerance to M. incognita could be valuable management approaches. Our objectives were to evaluate advanced cotton breeding lines for resistance and tolerance to M. incognita and to determine if a relationship between resistance and tolerance exists. Repr...
متن کاملTolerance to Rotylenchulus reniformis and Resistance to Meloidogyne incognita Race 3 in High-Yielding Breeding Lines of Upland Cotton.
Field experiments in 1992 and 1994 were conducted to determine the effect of Rotylenchulus reniformis, reniform nematode, on lint yield and fiber quality of 10 experimental breeding lines of cotton (Gossypium hirsutum) in untreated plots or plots fumigated with 1,3-dichloropropene. Controls were La. RN 1032, a germplasm line possessing some resistance to R. reniformis, and Stoneville 453, a cul...
متن کاملEvaluation of Nicotiana otophora as a Source of Resistance to Meloidogyne incognita Race 4 for Tobacco.
No currently available tobacco cultivar possesses resistance to Meloidogyne incognita race 4, nor has any source of resistance been reported within Nicotiana tabacum. The purpose of this study was to evaluate N. otophora acc. La Quinta as a source of resistance to this pathogen. Plants of tobacco cvs. NC 95 and NC 2326, N. otophora La Quinta and N. repanda were inoculated with second-stage juve...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولDamage Potential and Reproduction of Meloidogyne incognita Race 3 and M. arenaria Race 1 on Kenaf.
The effects of Meloidogyne incognita race 3 and M. arenaria race 1 on growth of kenaf cv. Everglades 41 was determined under greenhouse conditions. Seedlings of kenaf were inoculated with initial population densities (Pi) of 0, 625, 1,250, 2,500, 5,000, and 10,000 eggs/plant and placed on greenhouse benches in a randomized complete block design. Plant growth and nematode reproduction were asses...
