Evaluation of genetic dissimilarity in a segregating wine grape population

A. P. Viana, Riaz, S., and Walker, M. A., Evaluation of genetic dissimilarity in a segregating wine grape population, vol. 10, pp. 3847-3855, 2011.

This study examined the genetic diversity present in a population obtained by crossing two very distinctive varieties of wine grapes (142 progeny from a Riesling x Cabernet Sauvignon cross, including both parents, created at the University of California). The following list of morphological characters were evaluated and found to segregate in this population: cluster weight, cluster length, presence or absence of cluster wings, cluster wing length, number of berries, cluster density (CD), and berry weight.
