Genetic analysis for yield and its component in Himalayan Chenopod

A set of 53 genetically diverse genotypes of Chenopodium album L. originating from different agro-ecological areas of Himalayas and 3 exotic introductions of C. quinoa from South America was tested and analysed for genetic variability, correlation and path coefficient analysis. Phenotypic coefficient of variation and genotypic coefficient of variations were the highest for inflorescence length, number of leaves on main shoot, number of branches/plant and plant height. Heritability and genetic advance (in broad sense) were high for plant height, number of leaves on main shoot and days to mature. Grain yield showed positive association with inflorescence length, days to flower, number of branches/plant and leaf length. Inflorescence length had highest and positive direct effect on grain yield followed by days to flower and number of branches/plant. On the basis of variability and productivity parameters studied, inflorescence length, days to flower and number of branches/plant were observed to be the most potential traits for genetic improvement of Himalayan chenopod. Since late flowering and maturity beyond certain limit are not desirable, greater emphasis is given to inflorescence length and number of branches/plant while making selection or formulating component breeding programme for the genetic improvement of chenopod.
