PELUZIO, Joênes Mucci et al. Adaptability and stability of soybean cultivars under conditions of varzeas, in Tocantins State Brazil. Rev. Ciênc. Agron. [online]. 2010, vol.41, n.3, pp. 427-434. ISSN 1806-6690. http://dx.doi.org/10.1590/S1806-66902010000300015.
In order to evaluate the performance of soybean cultivars, three essays were carried out at Formoso do Araguaia, TO,Brazil, in the inter-cropping 2007 (15/05, 30/05 and 12/06). The experimental design employed was a randomized blocks with ten treatments and tree replications. The treatments were composed by ten soybean cultivar (DM Nobre, NIDERA In 7002, DM 247, DM 309, DM 339, M-SOY 8411, M-SOY 8914, M-SOY 8866, M-SOY 9350 and FT 106). In evaluating the performance of cultivars, a study was conducted of adaptability and stability by the methods of Eberhart and Russell (1966) and centroid. The average grain yield varied from 1023 kg ha-1 (15/05) to 1234 kg ha-1 (12/06), with a general average of 1142 kg ha-1. Based on the classification obtained by the methods of Eberhart and Russell (1966) and centroid, the cultivars DM Nobre, NIDERA In 7002, M-SOY 9350 and M-SOY 8914, were promising for the cultivation under conditions of inter-cropping. There was agreement among the methods on the classification of genotypes.
