Abstract:

In order to investigate the effects of environmental conditions on the quantitative traits in okra, 16 okra varieties were used as the materials in different sowing sites. The results showed that the leaf length and leaf width fluctuated greatly among varieties and sites. Therefore, the two traits were more affected by the variety and environment. The petiole length was less varied among varieties, but it was greatly affected by the environment. Fruit thickness and fruit length were prone to instability among the varieties, 9.68% and 8.68% respectively, while the average coefficient variation (CV) of fruit length and fruit diameter among varieties was less significant. The number of seeds per pod had significant differences in different sowing sites, so it was susceptible to environment. Dwarf type, long fruit type, and red fruit type of okra were more susceptible to the environment than other types.
