Registration of RMUP-C5, a random mated population of Upland cotton germplasm. Journal of Plant Registrations. 2:239-242.Interpretive Summary: RMUPC-5 is a population of cotton lines that resulted from the random mating of 11 diverse lines and varieties of cotton for 6 cycles.  An 11 parent, 55 line, half-diallel set of crosses were the starting point for the random matings.  The bulked pollen method was used for the random mating.  Parents used in development represented non-related or distantly related varieties or breeding lines from across the Cotton Belt of the United States.  Self-pollinated seed of the cycle 5 cross are being released.  Comparison of statistical relationships among traits in the parents and cycle 5 show that rearrangements of linkage blocks have occurred.  This germplasm should be of interest to breeders and geneticists across the U. S. Cotton Belt.
                                Technical Abstract: RMUP-C5 (Random Mated Upland Population Cycle 5) is a unique random mated germplasm population of Upland cotton, Gossypium hirsutum L., involving six cycles of random mating beginning with an 11 parent half diallel.  It has been assigned Reg. No.________: PI _________.  This germplasm was developed through cooperative research by the United States Department of Agriculture, Agricultural Research Service, Mississippi Agricultural and Forestry Experiment Station, North Carolina State Agricultural Experiment Station, and Cotton Incorporated.  Parents used in development represented non-related or distantly related cultivars or breeding lines from across the United States Cotton Belt.  The bulked pollen method of pollination was used in the development and there were six cycles of random mating with intercrossing of the F1 considered cycle zero.  Selfed seed of C5S1 have been released.  Comparisons of correlation coefficients between traits among parents, C0, and C5 cycles of random mating show reshuffling of linkage blocks.  Because this germplasm represents random mating among 11 very diverse breeding programs and includes parents from the major seed breeding companies, this population should be of value to breeders across the U. S. Cotton Belt.
