Carotenoid Content and Color in Diploid Potatoes

Relation between Carotenoid Content and Number of Genes per Cell in Diploid and Tetraploid Corn^

The evaluation of induced chromosome doubling as a method of plant breeding requires more information on the specific effects of chromosome doubling than is available at the present time. It is important that this information be procured from comparisons of related diploid and tetraploid strains of known origin and similar genetic constitution, Such strains have not been generally available bec...

Genetic analysis of isozyme variants in diploid and tetraploid potatoes.

Genetic segregations for six enzyme-coding genes were studied in diploid and tetraploid progenies obtained from various Solanum species. The loci identified are Prx-2, Prx-3, Prx-5, Mdh-1, Pgi-1 and Sdh-1. Prx-2 and Prx-3 were found to be linked; alleles at these loci segregated concomitantly in most of the diploid progenies. The putative homologous loci in tomato, Prx-2 and Prx-3, have also be...

Carotenoid content and flesh color of selected banana cultivars growing in Australia.

BACKGROUND The problems of vitamin A deficiency and chronic diseases have emerged in recent years in some countries in the Micronesian region. These problems are associated with the dietary shift towards imported processed foods and lifestyle changes. Research in the Federated States of Micronesia indicates that yellow- and orange-fleshed banana cultivars contain significant levels of provitami...

The carotenoid content of colostrum.

It was shown by van Eeckelen (1) that the yellow color of colostrum was due to the high content of carotenoids but the mechanism has not been clari i ed. By estimating the vitamin A level of the blood both during pregnancy and in the puerperal period, it has been shown that the plasma A level drops rapidly in the last stages of pregnancy even when adequate nourishment is given the mother. It ha...
