RESISTANCE IN WHEAT TO COCHLIOBOLUS SATIVUS, A CAUSE OF COMMON ROOT ROT

摘要: Resistance in wheat to Cochliobolus sativus, the main cause of common root rot cereals, was shown be a heritable character. Crosses were made between Thatcher, McMurachy, Willet, 492 (P.I. 94562-1), and 182 (PI. 4309), all which have some resistance C. sativus but can become heavily infected. The crosses gave rise both highly resistant susceptible lines that consistent their root-rot reaction at four or five locations over 2 years. A simple, practical method evolved determine reactions it basic selection. It relies upon natural field infections is oriented obtain high level disease plants. pedigree plant breeding used overcome problem posed by tendency for many plants escape infection. Isolations organisms from lesions assurance observed not Fusarium spp., may also rot. simplified ra...
