KSM 4402

KSM 4402 is a mid-early maize hybrid (Zea mays L.) intended for grain use. It is characterized by high yield, reaching 93.0–142.4 c/ha in the Central Chernozem region. The hybrid has a simple genetic structure and is adapted to various soil-climate conditions, ensuring stable quality and uniform seedlings.

The hybrid shows resistance to several diseases, including southern helminthosporium and ear rot, and has moderate resistance to bacterial disease. However, it is susceptible to stalk rot and may be damaged by the corn borer. The grain has a toothed shape with yellow coloration at the top, which is a distinctive feature of this variety.

KSM 4402 is recommended for cultivation in various regions, including the Central Chernozem and North Caucasus areas, due to its ability to quickly release moisture, drought resistance, frost tolerance, and lodging resistance. These traits make the hybrid attractive for farmers seeking high and stable grain yields under diverse climatic conditions.
