| Abstract | ||
| Characterization and evaluation of germplasm collections is considered an achievement as important as maintaining the collection. The objective of this work was to evaluate quantitative yield traits of a collection of Brazilian arracacha to identify high yielding, early and duplicated accessions. All 67 accessions of the arracacha collection were planted in an experiment at the Horticultural Research Station of Public University of Viçosa, MG, Brazil. A randomized complete block design with two replications was used. Each plot contained 15 plants in three rows spaced one m apart and with 0.40 m between plants. After eight months of planting, only 38 accessions presented three or more competitive plants in both replications. Yield of four commercial class root (Extra A, Extra, Special and First) and total commercial root yield were evaluated in three competitive plants of each plot. Sixteen accessions did not produce Extra A roots and eight accessions did not produced Extra roots. Accession BGH 6525 showed the highest total commercial root yield. Accession BGH 4551 showed highest Extra A root yield. Accession BGH 5747 showed highest Extra root yield. | ||
