Abstract
Abstract Anticipated climate change will alter the temperature and rainfall characteristics of crop growing seasons. This will require genetic improvement of crops for adapting to future climates for higher yields. The CROPGRO model for groundnut was used to evaluate genetic traits of Virginia and Spanish types of groundnut for various climate scenarios of India. The analysis revealed that productivity of groundnut can be increased in current and future climates by adjusting the duration of various life‐cycle phases, especially the seed‐filling to physiological maturity ( SD ‐ PM ). Increased maximum leaf photosynthesis rate ( AMAX ), increased partitioning to reproductive organs ( XFRT ) and increased individual seed‐fill duration ( SFDUR ) all contributed to the increase in pod yield in all climates. More determinate pod set (shorter PODUR ) was beneficial only in the water deficit environments. The positive effect of increasing specific leaf area ( SLA ) and leaf size ( SIZLF ) on pod yield was greater in environments more favourable for plant growth. Increasing reproductive tolerance to high temperature by 2 °C increased pod yield of groundnut in warmer environments, especially where the crop often suffers from drought. Increased adaptive partitioning to roots ( ATOP ) increased drought resistance of groundnut on high water‐holding capacity soils. Combination of traits had additive effects and pod yield increased substantially. These results indicate that the CROPGRO model can be used to assess the potential of individual or combination of plant traits for guiding breeding of improved groundnut varieties for current and future climates.
