MARIZA

The Mariza bean is a mid-late determinate variety of common bean (Phaseolus vulgaris L.) with a vegetative period of 78 to 88 days. The plant reaches a height of 50–59 cm, has a well-developed central stem and medium branching with 6–10 productive nodes. The leaves are trifoliate, of medium size, triangular to obovate in shape, and the inflorescences are racemes with 4–8 white flowers on elongated pedicels. The pods are of the shelling type, flat-round, 12–15 cm long with an acute tip; the seeds are smooth, shiny, oblong with white seed coat color and a characteristic yellow ring around the hilum. The Mariza variety is distinguished by high yield, which in the conditions of the Orel region averages 21.8 centners/hectare, exceeding standard indicators by 2.8 centners/hectare. The mass of 1000 seeds varies from 350 to 400 g. The bean is characterized by excellent cooking time – about 94 minutes, as well as high taste qualities. The seeds contain a significant amount of crude protein – from 25 to 30%, which makes this variety valuable in terms of nutritional properties and suitable for various culinary purposes. Mariza has resistance to the main bean diseases, including anthracnose, bacterial blights, and common and yellow mosaic viruses. Uniform ripening and determinate growth type allow for effective use of the variety for mechanized harvesting by direct combine harvesting. Due to the combination of high productivity, disease resistance, and high-quality seed characteristics, Mariza bean is a promising choice for cultivation in various regions.
