MOLECULAR BIOLOGY & PHYSIOLOGY Gossypium Lines Resistant to Rotylenchulus reniformis Vary in Sensitivity to the Herbicide Fluometuron

摘要: Reniform nematode (Rotylenchulus reniformis) resistance is being transferred to Gossypium hirsutum from its distant relatives. Reports of fluometuron damage LONREN lines with G. longicalyx raised concerns about introducing herbicide sensitivity other sources. The research objective was evaluate 15 sources reniform for their reaction three weeks after planting in a replicated greenhouse trial: two herbaceum accessions, four arboreum barbadense and introgressed (FR-05) or (LONREN-1 LONREN-2). control genotype cultivar Deltapine 161 B2RF. Across all rates tested, mean injury ratings accessions were greater than the control, whereas GB 713 TX 110 less. Regression analysis indicated that increased linearly increasing rate although A2-083 had more control. biomass decreased Pima PHY 800 exhibited reduction electron transport lower relationship between curvilinear, similar decreases response concentration lines. Increased could be introduced into through crosses distantly related species, but exception A2-083, did not respond differently
