It is also used for human consumption besides its several medicinal and industrial uses. Twenty seven promising genetic stocks in oats were evaluated under multicar system of fodder production. The field experiment was conducted in a randomized block design with three replication during winter 1989-90 at the Fodder Farm, Birsa Agricultural University, Ranchi. Genotypic and phenotypic coefficient of variation, heritability estimates, genetic advance and correlation alongwith path analysis and factor analysis were studied with respect to sixteen characters in the first cut and seventeen characters in the second cut taken for fodder. Phenotypic and genotypic coefficient of variations were high for plant height, atom dry matter percentage and leaf-stem ratio on green as well as dry weight basis in the first cut besides tillers/notre row in both the cuts. Heritability estimates alongwith genetic advance were high for plant height, leaf-stem ratio on green as well as dry weight basis and stem dry matter percentage in the first cut. Similarly, in the second cut, these were high for plant height, leaf-length, tillers/meter row, leaf length-widthEnglishThesis
