Abstract
ABSTRACT
Studies on “Screening of newly evolved selections of chrysanthemum
(Dendranthema grandiflora Tzvelev) for off-season flower production” were carried out at
the experimental farm of the Department of Floriculture and Landscaping of Dr. Y S Parmar
University of Horticulture and Forestry, Nauni, Solan (HP) during 2009. The investigations
were carried out on twenty-six selections of chrysanthemum in 4 inch earthen pots
containing a mixture of sand, soil and FYM in 1:1:2 proportions. Findings revealed that all
twenty-six selections are suitable for off-season flower production. However, they differed
significantly among themselves for various growth and flowering parameters. ‘Selection 19’,
‘Selection 21’, ‘Selection 44’, ‘Selection 64’ and ‘Selection 68’ showed optimum plant
height (1.5 to 2.5 times to the height of the pot) for growing as pot mum in 4 inch earthen
pots. All other selections attained more plant height than the ideal range. In general,
controlled photoperiod when applied was found better for flowering in all plantings over
natural. Flowering was observed much earlier under controlled photoperiod (165.83 days)
with improved quality of plants as compared to natural photoperiod (240.51 days). ‘Selection
43’ (187.17 days) was earliest in flowering whereas ‘Selection 76’ (225.00 days) took
maximum days to come into flowering. ‘Selection 64’ and ‘Selection 70’ remained
presentable for maximum duration (48.00 days) among all selections. Based on the findings
of present investigations, different selections have been assigned response groups under
controlled photoperiodic conditions, which varied from 8 to 14 weeks.
