ARALDO — medium-early hybrid of grain sorghum (Sorghum bicolor (L.) Moench), intended for cultivation in the North Caucasus region. The plant is of medium height with no or very weak anthocyanic pigmentation of seedlings and leaves, facilitating identification and care. The panicle is symmetrical, short, and dense, with a short peduncle and black glumes at maturity. The grain is round, white, with an endosperm combining glassy and floury texture, with a 1000-grain weight of approximately 28–34 grams. The ARALDO hybrid exhibits high yield potential, especially under drought conditions, due to its pronounced 'Stay-green' effect and resistance to apical sterility. Average grain yield reaches 21.8 centners per hectare, with a 14.7% increase over the standard, while the maximum yield in Rostov Oblast in 2017 amounted to 46.0 centners per hectare. The hybrid possesses good compensatory effect and structure, ensuring ease of harvesting. The sum of active temperatures for maturity is 1860°C, corresponding to a medium-early ripening period. The quality of ARALDO grain is high: starch content reaches 79%, protein exceeds 11%, and tannin content is very low (<0.14% dry matter). The hybrid is resistant to diseases such as fusarium, stem anthracnose, and apical sterility, enhancing harvest reliability. Sowing rate varies depending on conditions: 120–140 thousand seeds per hectare in drought-prone zones, up to 240 thousand seeds under irrigation. ARALDO is suitable for use in animal feed production, food industry, and bioenergy, making it a versatile and economically advantageous choice for farmers.
