ThesisItem Open Access Characterisation of oat (Avena sativa L.) genotypes for morphological and biochemical traits(CCSHAU, 2019) Pankaj; Phogat, D.S.Fifty six oat genotypes were evaluated for 28 morphological and biochemical traits to determine the effects and interrelationships among fodder and yield attributing traits of oats. The present investigation was conducted in randomized block design in three replications at the Research Farm of forage Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi 2017-18. The high significant variation among the genotypes for all the characters at genotypic level was shown by analyses of variance. The GCV and PCV revealed high level of difference for plant height, green fodder yield, dry matter yield, number of productive tillers/plant, seed crude protein and nitrogen content indicating the effect of environment on these traits. The high heritability was recorded for 100 seed weight followed by flag leaf length. days to 50% flowering, days to maturity, leaf: stem ratio, seed yield, 100-seed weight, total soluble sugars, reducing sugars and nutrient content i.e., phosphorus, potassium, iron, magnesium and zinc. Positive and significant correlations of green fodder yield were recorded with dry matter yield, plant height, number of productive tillers/plant and total soluble sugars. Path coefficient analyses revealed that characters plant height, number of productive tillers/plant, dry matter yield and total soluble sugars had positive and direct effects on green fodder yield. The genetic diversity analysis grouped 56 oat genotypes into eight major clusters. The eleven principal components had eigen values more than one and overall explained 73.66% of the total included variability.
