Genetic divergence among quinoa genotypes for morphological growth and panicle characters.

This study aimed to identify and select genotypes of quinoa ( Chenopodium quinoa ) with greater genetic distance between them, to compose groups of crossing. For both genotypes were evaluated two distinct populations of Chenopodium quinoa (Cherry Vanilla and Brilliant Rainbow), 15 quantitative characteristics being evaluated to determine the genetic distance and formation of groups with similar plants. The grouping was done by the method of neighbor furthest from the standardized mean euclidean distances, which allowed the division of 44 genotypes into three distinct groups. The crossing were those recommended involving genetic distance greater genotypes, genotype example 22 (group 1, Brilliant population belonging to Rainbow) genotype 34 (third group, belonging to the population Cherry Vanilla), genotype 22 x genotype 42 (group 2, belonging Cherry Vanilla population), genotype 34 x genotype 42, genotype 1 (group 1, the population belonging Brilliant Rainbow) genotype 34 and genotype 1 x genotype 42. It is noteworthy genetic differences among genotypes 34 and 42, since they belong  the same population (Cherry Vanilla) and were denoted as intersection possible to increase the genetic diversity of the population.
