In the quest to boost finger millet productivity, a team of researchers led by M. Chandhana Ishwarya from the Department of Genetics and Plant Breeding & Seed Science and Technology at Centurion University of Technology and Management has made significant strides. Their study, published in *Scientific Reports*, delves into the complex interplay between genotype and environment, offering promising insights for farmers and breeders alike.
Finger millet, a staple crop in many parts of India, is highly sensitive to environmental conditions, making it challenging to identify genotypes that consistently deliver high yields. To tackle this issue, the researchers evaluated 35 genetically diverse finger millet genotypes across three agro-ecological zones in Odisha, Jharkhand, and Bihar over two rabi seasons (2023–24 and 2024–25). By employing advanced statistical tools like AMMI (Additive Main Effects and Multiplicative Interaction) and GGE (Genotype and Genotype-by-Environment) biplot analysis, they were able to assess the genotype × environment interaction (GEI), stability, and adaptability of these genotypes.
The results were compelling. Genotype G18 (VR-1176) stood out as the most stable and high-yielding across all environments, followed by G13 (VL-Mandia-352), G28 (Bada Mandia), and several others. “The consistency of G18’s performance across different environments is a game-changer,” said Ishwarya. “This stability is crucial for farmers who often face unpredictable weather conditions.”
The study also identified Jharkhand (E2) as the most favorable environment for finger millet cultivation. This finding could guide farmers in making informed decisions about where to cultivate specific genotypes for optimal yields.
Adding a molecular dimension to the research, the team used UGEP markers 46, 66, and 68 to reveal polymorphic banding in high-yielding genotypes, validating the phenotypic observations. “The integration of phenotypic and molecular analyses provides a robust framework for identifying genotypes with both high productivity and yield stability,” explained Ishwarya. This dual approach not only enhances the accuracy of genotype selection but also supports breeding programs aimed at developing superior finger millet varieties.
The commercial implications of this research are substantial. By identifying stable and high-yielding genotypes, farmers can enhance their productivity and profitability. Breeders, on the other hand, can focus on these genotypes to develop new varieties that are resilient to environmental stresses. “This research paves the way for more targeted and effective breeding strategies,” said Ishwarya. “It’s a step towards ensuring food security and improving the livelihoods of farmers.”
Looking ahead, the findings from this study could shape future developments in finger millet cultivation and breeding. The use of advanced statistical and molecular tools offers a blueprint for similar studies in other crops, potentially revolutionizing the way we approach agricultural research. As the global demand for food continues to rise, such innovations are crucial for sustaining and enhancing agricultural productivity.
The research, led by M. Chandhana Ishwarya and published in *Scientific Reports*, not only advances our understanding of genotype × environment interactions but also provides practical solutions for the agriculture sector. It’s a testament to the power of interdisciplinary research in driving agricultural innovation and ensuring a more secure food future.
