Sorghum is sensitive to temperature lower than 15°C, most of the post rainy sorghum growing areas of India coincides with low temperature stress during flowering to seed set stage. In sorghum cold temperature at flowering seem to be more detrimental as it interacts with viable pollen production or pollen shedding which result in low yield. Hence the experiment was conducted to characterize a set of 16 sorghum genotypes which includes nine cultivars and seven hybrid parental lines in a control environment research facility at ICRISAT, India with three different temperature treatments. The three Day/Night temperature treatments were T1 (25°C/10°C), T2 (25°C/5°C) and T3 as control (natural environment).
