Abstract We measure the economic impact of varietal improvement and technological change in flue-cured tobacco across quantity (e.g., yield) quality dimensions under a voluntary constraint. Since 1961, breeders United States have been subject to Minimum Standards Program that sets limits on acceptable characteristics for commercial varieties. implement Bayesian hierarchical model contribution b...

Lentil is a nutritious food and one of the world's oldest domesticated legumes. The present studyevaluatedthe nature magnitude variability, heritability, genetic advance association among yield contributing traits in 24 lentils (Lens culinaris M.) genotypes. From 13 considered, phenotypic coefficients variation (PCV) were found higher than genotypic coefficient (GCV) which indicates less effect...

Guizotia abyssinica (L.F.) Cass. is one of the important oilseed crops cultivated in India. The seed plant used by tribal and rural people our country as a source edible oil. present investigation Niger deals with study back cross-program improvement variety. Unknown local variety (A) niger was selected non-recurrent parent because having some desirable characters like less vegetative growth (d...

Evaluation of three hundred and sixty four proso millet germplasm accessions were done during rabi, 2008-2009 at Department of Millets, Centre for Plant Breeding and Genetics, Tamil Nadu Agricultural University, Coimbatore to study genetic variability, diversity, correlation and path analysis of yield and its components. High variability observed for most of the characters indicated the scope o...
