ABSTRACT

An experiment was carried out to know the performance of daisy genotypes for gibberellic acid spray. Gibberellic acid spray at 150 ppm helped for influencing more vegetative growth, flowering and yield of daisy. Among the genotypes purple long petal produced maximum vegetative growth. The number of leaves and leaf area was maximum in light white dwarf genotype. Star white daisy genotype produced maximum leaf length. Whereas,  leaf width was recorded maximum in white daisy genotype. Dwarf pink  genotype was found to early for flowering. The flower yield was maximum in White tall, followed by purple long petal, purple multipetal and dark purple genotype. The spike length was maximum in purple multipetal genotype, Whereas, in interaction V1G1, V1G2 performed best for vegetative growth parameters. While, V2G1 and V2G2 produced maximum leaves per plant. The sucker production was maximum in V5G1 Early flowering was noticed in V9G1. Spike yield was found maximum in V8G1 followed by V1G1 and V4G1.
