The visual evaluation is the methodology most used in breeding programs for selection of double-haploids (DHs) in the field and discard of false-positives. Therefore, it is extremely important to construct character banks that allow the precise identification of double-haploids. The objective of this study was to evaluate the variability of 12 agronomic traits of interest for differentiation between maize double haploids and false-positive strains. 1440 lines, selected as double-haploids (DHs) from 12 donors were evaluated for 12 agronomic characteristics of interest, and separated between putative doubled haploids and false positives, which resulted in 432 DH lines. The results indicated that the parameters related to seed production were the most enabled the differentiation between double-haploids and false-positives. The use of agronomic character bank was efficient in the selection of putative double-haploids. |
