Plant breeders often handle large number of plants in a segregating population using limited resources. Therefore, the sooner they can reduce the number of plants to the barest minimum, but more importantly, to the most desirable and promising individuals, the better. The present short report deals with the selection of new advanced barley lines considering several agricultural traits simultaneously. We exemplify two new alternative uses of the Euclidean distance to identify the best 20% plant materials from a gamma radiation-mutant population. Plant height; days to flowering; plant lodging; coefficient of infection with leaf rust (Puccinia hordei), with powdery mildew (Blumeria graminis f. sp. hordei), with spot blotch (Cochliobolus sativus); yield; test weight; grain protein content and 1000 kernel weight were recorded and considered in the simultaneous selections described here. Essentially, selection indexes are proposed to calculate an overall value to a breeders' germplasm based on a number of traits. In reality, for many of the traits listed above, breeders are aiming for acceptable values such as for disease resistance and perhaps some morphological traits. For other traits, such as yield, the breeders are looking for the highest possible value. Therefore, each breeder will have different selection indexes; however, the mathematically defined indexes shown here would be particularly practical for plant breeders.
