Abstract

Rice is being cultivated in different regions based on the consumer preferences, marketability and adaptability. Basmati-type rice varieties are unaffordable due to high market prices and are also not recommended for cultivation in Tamil Nadu. Export demand for non-Basmati aromatic long slender grains is constantly increasing in the Middle East and European market. India is the largest producer and exporter of non-basmati rice in the world. Efforts were taken to develop non-basmati aromatic rice lines at TNAU, Coimbatore, and it has resulted in a non-basmati aromatic rice with long slender grain type rice culture CBMAS14142. CBMAS14142 was tested in various yield trials from 2011 to 2023. It registered an overall mean grain yield of 5858 kg/ha, which is 17.00 % higher than the check variety Pusa Basmati. CBMAS14142 is harbouring three major QTLs viz., qDTY 1.1, qDTY 2.1 and qDTY 3.1 from Apo conferring drought tolerance. This culture is suitable for cultivation during the Late Samba, Thaladi and Pisanam seasons in Tamil Nadu under transplanted or direct sown conditions. Hence, this high-yielding, mid-early, non-aromatic long slender rice culture CBMAS14142 with resistance/moderate resistance to pest and disease and good milling and cooking properties in comparison to the check variety Pusa Basmati was released as a new mid-early duration rice variety, CO58. It has also been notified by the State Variety Release Committee vide notification number Regn. No D.L-33004/99, S.No. 4027 dated 09^th October 2024 for commercial cultivation in Tamil Nadu.
