Breeding strategies for climate resilient vegetable production in tropical islands conditions

Shrawan Singh, Naresh Kumar Bainsla


The climate change is real phenomena and it will have impact on productivity and livelihood of primary farming options. Tropical Island regions are among the most vulnerable for this surfacing climatic catastrophe. The phenomena will lead to high temperature-high humidity-low light situation with excess or moisture stress. This will be helpful for pest dynamic but negatively affect crop plants. Slight changes in crop factors will have large impact on crop physiology and reproductive biology, resultantly larger change in their productivity and profitability. The change in climatic factors modifies genotype environment interaction for uptake of micronutrients by plants. Vegetables are succulent herbs which are more prone to both biotic and abiotic stresses. However, large germplasm and wide range of species and genetic diversity provide opportunity to develop climate resilient genotypes to minimize the impact and assure economic returns to the farmers. The paper proposes breeding strategies for vegetable crops which could help in climate resilient breeding program.
