TNAU 17005, a semidwarf, lodging-resistant rice with fine white grains and high yield potential, was released as Co43 for general cultivation in Tamil Nadu. It yielded an average 6.3 t/ha, 21.5% higher than IR20. Under saline-alkaline-water-logged conditions at Kaveripattinam, Barur, Paiyur, and Coimbatore (pH: 8.1 to 9.8 and EC: 0.3 to 1.3 d S/m), it yielded an average of 5.3 t/ha or 56.6% higher than IR20. Co43 also performed well at Machilipattam, Andhra Pradesh, with soil Ph 8.2 and Ec 9.9 d S/m and in International Rice Testing Program nursery trials. The grain quality is good for raw and boiled rice. Co43 is tolerant of green leafhopper and moderately resistant to blast, brown spot, and leaf blight. It can be grown in all seasons in Tamil Nadu
