VERIFY THE RESISTANCE TO RHIZOMANIA DISEASE IN SUGAR BEET (BETA VULGARIS L.)
A. A. Nouhi, R. Amiri, A. Haghnazari
Abstract: The Rhizomania disease is one of the destructive diseases in sugar beet that causes a great deal of damage to agriculture industry and causes the reduction in crops in Iran and all over the World. One of the effective solutions in challenging with virus is use of resistant cultivars in farms. The resistant cultivars have Rz 1 and Rz2 genes which are resistant to virus. In this study a contaminated soil with Rhizomania virus (which had been brought from a known region with contaminated soil) used in a greenhouse test with two different populations. The first population was the result of cross between a Holly 1–4 resistant parent with an annual susceptible parent and the second population was the result of cross between 261 cultivar susceptible parent and resistant WB42 parent. The immunology test was done to distinguish between susceptible and resistant plants then inheritance of resistant gene(s) to disease and statistical analysis by the results of this test was verified.
