Cercospora beticola Sacc. causes leaf spot diseases of sugar beet (Beta vulgaris L.) (2,19,21), related species in the family Chenopodiaceae (6), and, in recent reports, on safflower (Carthamus tinctorius L.) (11,12) and German statice (Goniolimon tataricum) (3), belonging to plant families outside of the Chenopodiaceae family. Cercospora leaf spot (CLS) is the most important foliar disease of ...

in process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight .the volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. drought stress and dehydrated root reduce. the volume of the pulp extract of 23 ml. the objective of this experiment was to determine the proper...

The yield of sugar beet has continuously increased in the past decades. The question arises, whether this progress will continue in the future. A key factor for increasing yield potential of the crop is breeding progress. It was related to a shift in assimilate partitioning in the plant toward more storage carbohydrates (sucrose), whereas structural carbohydrates (leaves, cell wall compounds) u...

The most important step in developing of a sugar beet hybrid for target trait is selection of CMS line or single cross. In the present study, 12 progenies derived of 4 sugar beet lines(as female parent) with different level of rhizomania resistant, along with 3 pollinators 27270, 27273 and 27274(as male parent) and parents were evaluated in two locations (Mashhad and Shiraz) with rhizomania inf...
