Forty two rice first filial crosses were generated during rabi 2018-19 period utilizing seven lines and six testers adopting line x tester crossing fashion to get a hold of yield superiority hybrids with blast tolerance. The heterotic components were investigated for yield and quality traits on test hybrids. The results signified the greater heterotic vigour for yield and its component traits while the quality traits particularly length breadth ratio, length elongation ratio breadth elongation ratio and amylase content adjudged to express lower level of heterosis. Thirty five crosses exhibited significantly positive value for relative heterosis while twenty four hybrids showed positive and significant heterobeltiosis. The cross involving White Ponni (128.73 to 157.16), IR 20 (102.85 to 133.32) and CO 50 (95.80 to 125.49) as female parent witnessed to perform extremely superior for yield among the lines deployed. Considering yield and its component traits, the crosses viz.,

Groundnut variety COGn 4, a hybrid derivative of TMV 10 x ICGS 82 was released during January 2001 for Tamil Nadu. It has desirable attributes viz. high pod yield, high oil content, bold kernel with less incidence of bud necrosis. It matures in 110 days and gives an average yield of 1500 and 1950 kg ha' under rainfed and irrigated conditions respectively. This variety is suitable for both rainfed and irrigated conditions and can be grown during kharif, rabi and summer seasons.
