Executive Summary During 2011-12, Central Rice Research Institute released thirteen ecosystem and trait specific varieties include which upland (1) shallow lowland (1), deepwater (2), irrigated (2), coastal saline (2), aerobic (1), aromatic (2) and two varieties resistant to bacterial blight were identified for bacterial blight endemic areas of Odisha by using marker assisted selection (MAS). Out of the 132 advanced breeding lines nominated under different trials under AICRIP, 41 were promoted to next level of testing. Sumit (CR662-22-1-1-1-1; IET19913) developed from the cross IR32/IR13246 was released for rainfed lowland areas of Odisha. It has maturity duration of 150 days, plant height of 108-115 cm and long bold grain with an average yield of 5.20 t ha -1 . Satyabhama (CR2340-11; IET20148) developed from the cross IR 31238-350-3-2-1/IR41054-102-2-3-2 was released for favourabe upland areas of Odisha. It has maturity duration of 110 days with semi-dwarf plant type (100-105 cm), medium slender grain with an average yield of 4.70 t ha -1 under normal conditions and 2.30 t ha -1 under drought situation. Jalamani (CR 2282-1-2-5-1; IET20214) developed from the cross Panikekoa/Ambika was released for deepwater rice areas of Odisha. It has maturity duration of 160-165 days, tall plant type (150 cm) with medium slender grain and an average yield of 4.60 t ha -1 . Jayantidhan (CR2080-169-3-2-5-2; IET20706) developed from the cross Samson Polo/Jalanidhi was released for deepwater rice areas of Odisha. It has maturity duration of 165-170 days, tall plant type (170 cm) with medium slender grain and an average yield of 4.60 t ha -1 . It is tolerant to stem borer. Pyari (CR2624-IR 55423-01; IET21214) developed from the cross UPL RI5/IR12979-24-1 (Brown) was released for aerobic/ water limiting rice areas of Odisha. It has maturity duration of 115-120 days, semi dwarf, non-lodging plant type and short bold grain with an average yield of 4.50 t ha -1 . Hue (CRK26-1-2-1; IET19351) developed from the cross IR 42/Rahaspanjar was released for mid duration irrigated ecology of Odisha state. It has maturity duration of 130-135 days, long slender grain and average yield of 4.50 to 5.50 t ha -1 . Luna Sankhi (CR2577-1; IET21237) developed from the cross IR31142-14-1-1-3-2/IR71350 was released for dry season cultivation in coastal saline areas of Odisha. It has maturity duration of 105-110 days, plant height of 105 cm, medium slender grain and has average yield of 4.60 t ha -1 . Luna Barial (CR2092-158-3; IET19472) developed from the cross Jaya/Lunishree was released for wet season cultivation in coastal saline areas of Odisha. It has maturity duration of 150-155 days, plant height of 120 cm, medium slender grain and has average yield of 4.10 t ha -1 . Improved Lalat (CRMAS2621-7-1; IET21066) developed from the cross Lalat/IRBB60 was released for growing in the bacterial bight endemic areas of Odisha. It has long slender grain, high HRR with intermediate amylose content, maturity duration of 130 days with an average yield of 4.50 to 5.00 t ha -1 . It is resistant to gall midge and moderately resistant to stem borer. Improved Tapaswini (CRMAS2622-7-6; IET21070) developed from the cross Tapaswini/IRBB 60 was released for growing in the bacterial blight endemic areas of Odisha. It has short bold grain, high HRR with intermediate amylose content, maturity duration of 130 days with an average yield of 4.00 to 5.00 t ha -1 under normal condition. It is resistant to major pest like BPH, YSB and WBPH and moderately resistant to stem borer. Poorna Bhog (CRM2203-4; IET18008) developed from Pusa Basmati-1 through mutation breeding was released for irrigated areas of Odisha. This aromatic variety has 100 cm plant height, 140 -145 days to maturity with long slender grain and yield capacity of 4.50 to 5.00 t ha -1 . Its grains are translucent without chalkiness with desirable cooking and eating qualities. CR Dhan 907 (IET21044), an aromatic short grain culture developed from Pusa44/Dubraj with semidwarf stature giving a yield of 4.00 t ha -1 was identified for CVRC release in four states (Odisha, Chhattisgarh, Gujarat and Andhra Pradesh). CR Dhan 303 (CR2649-7; IET21589) derived from the cross between Udaya/IET16611 was identified for irrigated areas of Madhya Pradesh, Uttar Pradesh and Odisha. This culture is moderately resistant to leaf blast, neck blast, sheath rot and rice tungro disease with an average yield of 5.00 t ha -1 . Fifteen genotypes were identified having resistance to various biotic stress including three cultures (CR2652- 14, CR2656-11-3-4-2 and CR2644-2-6-4-3-2) resistant to rice tungro disease with low susceptibility index less than 4.0 in NSN 1 and NSN 2 trial, six genotypes CRRI ANNUAL REPORT 2011-12 11
