Improving environmental adaptation in crops is essential for food security under global change, but phenotyping adaptive traits remains a major bottleneck. If associations between single-nucleotide polymorphism (SNP) alleles and environment of origin in crop landraces reflect adaptation, then these could be used to predict phenotypic variation for adaptive traits. We tested this proposition in the global food crop Sorghum bicolor, characterizing 1943 georeferenced landraces at 404,627 SNPs and quantifying allelic associations with bioclimatic and soil gradients.

Bad news is good news; media revel in news of crisis and catastrophe. No news is bad news; some space has to be filled with news if anyone is going to look at accompanying views and ads. But if there is no news, pseudo-news can be invented, also known as speculation. Speculation is possible all round the year on weather, for luckily, India is situated far enough from the equator to have pronounced seasons.
