Abstract:: With block light net simulating the low light condition，seven pepper combinations which were cultivated in Horticultural Institute of Zhumadian Institute of Agricultural Sciences in recent years were used to evaluate their low light tolerance by means of factor analysis.Botany traits and yield traits，plant height and stem diameter were reference index，leaf area and specific leaf weight were important indicators，but crop and chlorophyll a/b ratio were the most important indicators.The results showed that low light stress led to increase the plant high and leaf area，reduce stalks and specific leaf weight and yield and chlorophyll a/b ratio.The change of chlorophyll a/b ratio and yield were basically identical.The study accessed the low light tolerance of the different pepper combination successfully.
