The researchers studied 15 different types of maize to see how they performed in different growing seasons in the North Western Himalayas. They found that some hybrids were more stable in their grain yield across different seasons, while others were more affected by the specific environment they were grown in. Three hybrids, UDMH 121, UDMH 114, and UDMH 128, consistently produced good yields. This means that when choosing a maize hybrid for a specific location, it's important to consider how it will perform in that particular environment. The researchers plan to continue their study by testing more locations in the future.
