Abstract
An investigation was carried out to evaluate gaillardia (Gaillardia pulchella
Foug.) genotypes for growth, quality and yield parameters under Northern dry zone of
Karnataka under the Department of Floriculture and Landscape Architecture, College
of Horticulture, Bagalkot, during the year 2017-18. The experiment was laid out in
simple randomized complete block design with two replication and fifteen treatments
Among the fifteen genotypes studied, UHSBGL-14 recorded maximum plant
height (52.64 cm), number of primary (17.15) and secondary branches (27.75), plant
spread East-West (47.91 cm) and North-South (48.32 cm), number of leaves per plant
(463.35) and LAI (9.16 cm2). The minimum days for first flower bud initiation (59.00
days), minimum day for 50% flowering (69.05 days), maximum flowering duration
(131.00 days) and maximum shelf life (14.90 hr) was found in UHSBGL-14. Genotype
UHSBGL-1 recorded minimum days to harvest (3.58 days). Maximum individual
flower weight was recorded in genotype UHSBGL-5 (8.99 g). Genotype UHSBGL-10
recorded maximum length and width of ray floret (3.00 cm and 0.81 cm) respectively
and flower disc diameter (4.35 cm). Number of flower per plant (203.30). Flower yield
per plot (2.10 kg) and per hectare (5.26 t) was found maximum in genotype UHSBGL-
14. Overall consumer acceptance for loose flowers and garden display was found
maximum in genotype UHSBGL-14.Among the genotypes evaluated UHSBGL-14,
UHSBGL-5 and UHSBGL-15 genotypes were found most suitable to grow under
Northern dry zone of Karnataka respectively.
