RM 422: A Benchmark in Supersweet Maize

RM 422, developed by the All-Russian Scientific Research Institute of Maize and SSP Kukuruza, represents a strategic choice for growers seeking reliable, domestically bred supersweet maize. By leveraging SH2 (supersweet) endosperm technology, this variety addresses the market's need for enhanced sugar content that remains stable post-harvest.

Why SH2 Genetics Matter

The core of RM 422's market value lies in its SH2 gene. Unlike standard sweet corn, this variety maintains its sugar levels significantly longer, preventing rapid conversion into starch. This characteristic is vital for supply chains, ensuring that the consumer receives a product that retains its signature dessert flavor even after storage and transportation.

Key Agronomic Specifications

• Maturity: 70–73 days. This medium-early timeline offers flexibility for planting schedules and multi-stage harvesting strategies.
• Physical Profile: The plants reach a height of 150–200 cm. This uniform stature makes the variety well-suited for mechanical harvesting and provides excellent lodging resistance.

Designed to thrive in domestic climatic conditions, RM 422 avoids the performance volatility sometimes observed in imported hybrids. Its consistent yield and robust development make it a preferred variety for both the fresh produce market and the food processing industry, including canning and freezing operations.
