Pedigree
CR951-210 was derived from one S1 family from the F1 population hybrid between CR11 x Y090. Y090 is a multigerm, self-incompatible, composite line recombining full-sib selections from lines such as C78/2 (PI 593695), C82 (PI 593675), and C80 (PI 593672) that have been developed for combined resistances. CR11 (PI 636343) male sterile plants were topcrossed to virus yellows resistant line Y090. F1 plants were randomly selected and selfed. The ensuing S1 families were evaluated for components of sugar yield under nondiseased, rhizomania, cercospora leaf spot, virus yellows, and bolting conditions. One S1 line with high combining ability for sugar yield was selected and increased in bulk to produce CR951-210.
Comments
CR951-210 is a narrowly based germplasm. In tests at Salinas, Fort Collins, East Lansing, Kimberly, and Shakopee, MN, it showed moderate resistance to cercospora leaf spot (Cercospora beticola). It is green hypocotyl colored (rr), multigerm (MM), self compatible (Sf), and segregates for genetic male sterility (A:aa) and resistance to rhizomania (Rz1:rz1rz1) caused by Beet necrotic yellow vein virus. It is moderately resistant to powdery mildew (Erysiphe betae) and moderately susceptible to curly top (Beet curly top virus). CR951-210 may be unique in combining resistance to cercospora leaf spot and nonbolting tendency with tolerance to virus yellows caused by combinations of Beet yellow virus and Beet chlorosis virus. Under diseased conditions it has good sugar concentration and high sugar yield combining ability. It should be adapted to the areas in California subject to Cercospora, rhizomania, curly top, virus yellows, and other diseases. About 6% or the germplasm of CR951-210 is from sugarbeet accessions obtained from Rovigo, Italy from so-called Munerati and Alba material.
