Electrophoretic protein differences between selected varieties and lines of upland cotton

One of these problems is caused by climatic conditions which dictate the use of stormproof varieties of cotton in the above mentioned area, Economic returns from cotton in this area would generally be greater if adapted longer staple non-stormproof varieties could be grouin (47), Genetic studies of stormproof character have been hampered by difficulties in classifying individual cotton plants as stormproof or non-stormproof (23,32). Consistent electrophorectic protein differences between stormproof and nonstormproof varieties could provide a criterion for classification and facilitate the incorporation of stormproof character into longer stapled varieties. The second problem involves the need for a protection or patenting program for new cotton varieties, To effectively protect new varieties criteria must be established that describe each variety precisely, rÃlorphological characteristics presently used are somewhat arbitrary and time consuming (28), The use of biochemical characteristics is a logical and promising way to describe new varieties. However, biochemical differences between varieties must be 'determined and cataloged before they can be used as criteria for varietal identification.
