    Screening for non-bolting type (S) of Amaranthus suited for year-round planting
    (Department of Olericulture, College of Horticulture, Vellanikkara, 1982) Devadas, V S; KAU; Gopalakrishnan, P K
    The investigation, "screening for non-bolting type(s) of amaranthus suited for year round planting" was conducted during April 1981 to March 1982 at Instructional Farm of College of Horticulture, Vellanikkara with the following objectives - to isolate stable line (s) for yield and bolting, line (s) with negligible content of antinutrient factors. ie., nitrate and oxalates and to ascribe the reasons for bolting . The 25 amaranth genotypes belonging to four botanical species were grown in a randomised block design with 2 replications at monthly intervals. All the 25 genotypes varied significantly with regard to the total yield yield components and bolting. The heritability, phenotypic coefficient of variation and expected genetic advances were high for all the characters.
