Objectives A field experiment was conducted to evaluate ten hybrid maize for photosynthetic traits. Ten hybrid were replicate thricely under Randomized Complete Block Design (RCBD) during winter season of 2018. SPAD 502 Plus meter was used for SPAD value measurement. Vegetative stage all photosynthetic measurement taken from T1 (top most leaf) and T3 (2nd leaf from top leaf) leaves of 5 plants of one plot during 30 days interval. For reproductive phase data taken from Eo/ eo (Leaf attach to cob/ear), E2 or e2 (2nd leaf from Eo /eo leaf) leaves during entire period of grain filling at 10 days intervals. Same leaves were used for overall data collection.
Results Result showed that significantly different SPAD value were observed for different age and leaves of maize during pre and post anthesis. SPAD value increase with increase in age and decrease at the time of maturity. During vegetative and juvenile phase T3 leaf has more SPAD value than T1. During reproductive stage eo leaves had more SPAD than e2 leaves, so center leaf of maize contributes more to grain yield. Correlation studies showed that there is strong positive correlation between different stage of SPAD with grain yield.
