This report is a catalog of genetic relations among 258 soybean cultivars released by public agencies during 1945-88. Its purpose is to provide soybean breeders with a practical guide for the selection of good parental material and for the preservation of genetic diversity in their breeding programs. To develop this guide, we used pedigree analysis, a common technique in plant breeding. Based on the concept of allelic identity by descent, this approach uses the familial relationships among cultivars to quantify the probability of two cultivars having identical genes at a random locus. This probability is known as the coefficient of parentage. The calculation of coefficient of parentage requires some assumptions regarding relations among the ancestors of modern soybean cultivars. Because these assumptions have some potential for altering the interpretation of our results, we present two estimates of genetic relatedness of soybean cultivars, using different assumptions for calculation in each analysis. In the first analysis, we make the convertional assumption that the original plant introductions used in North American soybean breeding (those for which pedigrees are unknown) are all equally unrelated. In the secon, which we refer to as a genetic similarity analysis, we assume that patterns of relatedness do exist in this original founding stock. Gizlice (1991) compared phenotypes of 14 plant introductions that constitute 70% of the genetic material use in U.S. soybean breeding and also described patterns of diversity within this group. We superimposed this information on the conventional pedigree analysis to obtain genetic-similarity estimates for the 258 cultivars. As an additional measure of diversity in soybean, we also present the coefficient of parentage between the cultivars mentioned and 50 major ancestors of the modern soybean. Our results summarize the complicated pedigrees in a simple way so that breeders can easily determine the genetic diversity of the material in their program.

Existem muitas de cultivares de bananeiras cultivadas tradicionalmente no Brasil (Nanica, Nanicão, Grand Naine, Prata-anã, Pacovan, Maçã, dentre outras), porém quando se considera algumas características como porte da planta, produtividade, tolerância à pragas, doenças, seca e frio, todas apresentarem pelo menos uma característica indesejável para a exploração comercial (SILVA e ALVES, 1999). |
