High yielding, semi compact, drought tolerant, early maturing new samai variety ATL 1
Abstract
A high yielding and early maturing Samai TNPsu 177 was developed at the Centre of Excellence In Millets, Tamil Nadu Agricultural University, Athiyandal and released as ATL 1. It is a derivative of CO(Samai) 4 x TNAU 141 with 1587 kg/ha grain yield and 3109 Kg/ha of straw yield in 85-90 days under rainfed condition. Being a short duration variety, this variety fits well in the existing double cropping rainfed condition of North, North western and western zones of Tamil Nadu. Samai is grown in June- July as a preceding crop to horsegram in more than 80,000 ha. It has yield advantage of 11.2 and13.7 percent for grain yield while11.8 - 14.4 percent for straw yield over the check varieties viz.,CO(Samai) 4 and Paiyur 2. Samai line TNPsu 177 has strong and sturdy culm with long, semi-compact panicles and drought tolerance. The plant has 6-8 productive tillers and non-shattering grains. It has special attributes like easy threshability, synchronous maturity and non-lodging growth habit. The grains are bold with attractive golden yellow colour. In view of stable yield performance across seasons and locations, special attributes and drought tolerance, Samai TNPsu 177 is proposed for release as ATL 1 to fulfill the long felt need of the drylands, hilly and tribal areas in Dharmapuri, Thiruvannamalai, Vellore, Salem and Krishnagiri districts of Tamil Nadu where samai is predominantly grown under rainfed condition.
