摘要

巴西的马铃薯生产以源自美国和欧洲的品种为基础;然而，这些品种是在与巴西不同的环境条件下培育出来的。本研究旨在评价由法国拉夫拉斯联邦大学(universsidade Federal de Lavras)开发的18个马铃薯无性系(MLG)和4个品种在巴西米纳斯吉拉斯州6个环境中的适应性和稳定性。评价了以下性状:可售块茎产量(MTY)、比重(SG)和块茎外观(TA)。无性系、环境和基因型与环境互作对各性状均有显著影响。GGE-biplot分别解释了MTY、SG和TA的G+G×E平方和的71.78%、98.13%和62.86%。3个MLG无性系的适应性、稳定性和生产性能均优于其他品种，具有较好的推广潜力。

Stability of potato clones resistant to potato virus Y under subtropical conditions

Brazilian potato production is based on cultivars originating from the USA and Europe; however, these cultivars were developed under different environmental conditions than those found in Brazil. The aim of this study was to evaluate the adaptability and stability of 18 potato clones (MLG), developed by the Universidade Federal de Lavras, and four cultivars in six environments in the state of Minas Gerais, Brazil. The following traits were evaluated: marketable tuber yield (MTY), specific gravity (SG), and tuber appearance (TA). Clones, environments, and the genotype × environment interaction had significant effects on all traits. The GGE-biplot explained 71.78, 98.13, and 62.86 % of the sum of squares from the G+G×E for MTY, SG, and TA, respectively. Three MLG clones had higher adaptability and stability, as well as better performance, than the cultivars, making them good candidates for release as cultivars.

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 The article must be unpublished.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.
