Abstract

Twenty-nine arracacha clones were evaluated in 2002/2003, at the Horticultural Research Garden of the Federal University of Vicosa. A randomized complete block design with 30 treatments and three replications was used. Each plot contained 75 plants in three 10 m long rows (rows spaced 1 m apart and plants 0.40 m). Six competitive plants were picked eight months after planting. Sprouts were collected from the remaining plants eleven and a half months after planting. Ten quantitative and four qualitative traits were evaluated. Variance analyses showed significance of all but one quantitative trait (non-commercial root weight). Genetic distances were estimated by Mahalanobis' generalized distance and clones grouped by clustering, applied to quantitative traits. Our goal was to identify early high yielding, healthy, and genetically diverging clones. Clones BGH 4550, BGH 5742, and BGH 6425 seemed to be promising future varieties, and 10 clones are interesting for further breeding work.

荸荠育种中的无性系选择

2002/2003年，在维科萨联邦大学园艺研究花园对29个阿拉恰无性系进行了评估。采用随机完全区组设计，共30个处理，3个重复。每个地块包含75株植物，每行10米长，每行间隔1米，植株0.40米。种植8个月后采摘6株竞争植物。在种植11个半月后，从剩下的植株上收集芽。评价了10个定量性状和4个定性性状。方差分析表明，除1个数量性状(非商品根重)外，其余性状均显著。遗传距离由马氏鱼广义距离估算，无性系聚类分组，应用于数量性状。我们的目标是确定早期高产、健康和基因分化的克隆。无性系BGH 4550、BGH 5742和BGH 6425是未来有发展前景的品种，其中10个无性系值得进一步研究。

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
