Breeding and biotechnological approaches for improving Dioscorea bulbifera in the Western Himalayas

Abstract

In the Western Himalayas, Dioscorea bulbifera, commonly known as the air potato, plays a significant role in traditional diets and medicine. Despite its potential, the species faces challenges such as genetic erosion, low yield, and susceptibility to diseases, which hinder its broader utilization. This study explores breeding and biotechnological approaches to address these issues, aiming to enhance the agronomic and medicinal value of D. bulbifera. Through genetic diversity analysis, marker-assisted selection, and advanced tissue culture techniques, we identified and propagated superior genotypes characterized by higher yields, increased disease resistance, and enriched phytochemical profiles. Our findings highlight the potential of combining traditional breeding with modern biotechnology to improve underutilized crops like D. bulbifera, offering new opportunities for sustainable agriculture and economic development in mountainous regions.
