Soybean RGT STUMPA

The RGT STUMPA soybean variety is an early-maturing, semi-determinate plant type included in the State Register for the Central Chernozem and North Caucasus regions of Russia. The plant has low to medium height, with distinctive features: hypocotyl with anthocyanin pigmentation, reddish-brown pubescence on the main stem, purple flowers, and yellow seeds with a gray hilum. The lateral leaflet of compound leaves is ovate-lanceolate. The vegetative period is approximately 111-114 days, ensuring early maturity.

In terms of yield, the variety demonstrates high performance: average seed yield in the Central Chernozem region reaches 22.3 c/ha, and in the North Caucasus region — 23.2 c/ha. Maximum yields were recorded in 2019 and 2020 at specialized grain farms, where yields reached 32.3-36.3 c/ha. The 1000-seed mass varies from 145 to 154 grams, indicating large seed size and high quality.

The protein content in RGT STUMPA seeds ranges from 38.8% to 40.8%, and fat content is approximately 20%, making this variety attractive for processing and feed purposes. The high levels of protein and fat ensure high nutritional value of the product. Due to its agronomic characteristics and high yield performance, RGT STUMPA is a promising choice for cultivation in the specified regions for obtaining high-quality, high-yield soybean crops.
