The "Amber" bean variety is a medium-maturity forage crop with a growing period of 100–120 days. The stem height ranges from 109 to 123 cm and is glabrous, which facilitates field management. The leaves are oval, entire-margined, covered with a waxy coating, and the flowers are white.
The pods are dark brown, typically containing 5–6 seed groups; the seeds themselves are light yellow, oval, with a black hilum. The mass of 1000 seeds ranges from 470 to 515 g. In the absolute dry matter of green mass, protein content reaches up to 20%, making the plant a valuable forage resource.
The variety yields steadily high: during multi-year trials, an average seed yield of 2.0 t/ha and green mass yield of 20.5 t/ha were recorded. Under optimal conditions, maximum yields of 3.9 t/ha for seeds and up to 52.5 t/ha for green mass are possible. The plant shows low susceptibility to diseases, which enhances its stability in agro-technical systems.
