The performance of 52 doubled haploid (DH) lines from two barley crosses was compared with lines developed by the pedigree (PD) and the single seed descent (SSD) methods. The comparison was made in hill plot tests over a 2-yr period at two locations. There was no difference in grain yield, heading date and plant height between the DH populations and the populations derived by the other two breeding methods. Similar means and ranges, genetic variances and frequencies of desirable genotypes were obtained in the populations produced by the three breeding methods for grain yield, heading date and plant height. The mean grain yields of superior lines were similar for all three methods. There was no indication of deleterious effect of complete homozygosity in the DH lines. In the two crosses examined, the materials generated by the DH method were as good agronomically as those produced by the PD or SSD methods. It was concluded that the doubled haploid technique is a very useful tool for producing high yielding homozygous barley lines in a relatively short time.

RESUMO O gênero Capsicum, de grande importância mundial, ocorre tanto nos países tropicais como nos de clima temperado. De um total de 31 espécies, apenas cinco são consideradas domesticadas, as demais, semidomesticadas ou silvestres. Nos últimos anos, as pimentas passaram a ter maior demanda pelo mercado e, consequentemente, os trabalhos relacionados à caracterização, melhoramento e obtenção de novas cultivares receberam mais atenção dentro de instituições públicas de ensino e de pesquisa, assim como no setor privado. Este trabalho foi desenvolvido na Embrapa Hortaliças, com objetivo de caracterizar morfoagronomicamente linhagens de pimenta do tipo Jalapeño Amarelo, atividade essencial para o desenvolvimento de cultivares. Primeiramente foram identificadas três plantas segregantes da cultivar comercial do tipo Jalapeño Vermelho, que apresentaram frutos de coloração amarela. Com base nesse material, o trabalho foi desenvolvido em duas fases: na primeira, obtenção de linhagens homozigotas pelo método de Descendência de Uma Única Semente (do inglês Single Seed Descent); na segunda, caracterização das linhagens obtidas através de cinco descritores morfológicos de Capsicum propostos pelo IPGRI (1995) e posterior avaliação qualitativa das linhagens em campo, sendo usado o teste Scott-Knott para a análise estatística. Conclui-se que o método de melhoramento utilizado foi satisfatório, visto que, em 30 meses de trabalho, as linhagens avançaram cinco gerações (S5). A caracterização morfológica e a avaliação qualitativa permitiram identificar diferenças significativas entre as linhagens. As linhagens promissoras identificadas neste trabalho foram CNPH 25.368, CNPH 25.373, CNPH 25.374, CNPH 25.375 e CNPH 25.377.
