  Slow Varietal Turnover in Soybean a Challenge to Climate Change Adaptation and Disease Control: Pathways to Circumvent
  Author(s): Chandra S. Nuthalapati*
  
  The ongoing cultivar transformation of crops termed ‘varietal turnover’ manifests in transition from the existing improved varieties to the new improved varieties, as farmers in most of the world replaced landraces during the Green Revolution and subsequent decades. Younger varieties significantly enhance yield through genetic gains and protection against climate change and associated changes that lead to changing crop cycles and multiple disease and insect challenges. Studies documented significant yield increases with frequent varietal change and vice versa. However, long varietal age in developing countries, especially in climate change-vulnerable countries of Africa and South Asia, poses challenges for climate adaptation, crop protection, yields, and consequently, poverty reduction and food and nutrition security. Farmers continuing with older varieties face a ‘t.. View more»
