Physiology traits studied include OP (osmotic potential), δ¹³C (carbon isotope ratio), Chl (chlorophyll content), and CT (canopy temperature). Production traits studied were BW (boll weight), SC (seed cotton yield), HI (harvest index), and DM (dry matter weight). Fiber quality traits comprise FF (fiber fineness), FS (fiber strength), and FL (fiber length).
