Abstract Four major leaf shapes exist in tetraploid cotton ( Gossypium hirsutum L.): normal, sub‐okra/sea‐island, okra, and super‐okra. The majority of upland G . ) varieties the United States possess a normal shape. However, other three were reported to show few production advantages such as accelerated flowering rates, early maturity, reduced lint trash boll rot, increased pest resistance. In this study, we evaluated leaf‐shape isolines LA‐213‐okra, LA‐213‐normal, LA‐213‐super‐okra, LA‐213‐sub‐okra for physiological traits related yield performance identified associated with superior mechanisms. During stage, narrow shape isolines, LA‐213‐okra LA‐213‐super showed 6%–19%, 0%–15%, 3%–73% greater chlorophyll index, quantum efficiency photosystem II, photosynthetic rate, respectively, than LA‐213‐normal isolines. Further, water use LA‐213‐super‐okra was 12%–22% lower that With performance, okra super‐okra offer useful trait variation breeding variety development.
