Abstract
An experiment entitled “Studies on performance of different ginger genotypes
under Marathwada condition” was conducted in kharif season at Department of Horticulture,
Vasantrao Naik Marathwada Krishi Vidhyapeeth, Parbhani, during 2011-2012. The experiment
was laid out in Randomized Block Design with four replications and five genotypes viz.,
Taklinadim, Shilegaon, Paithan, Gangapur, Kannad. Similar package of practices was followed
to five genotypes in trial.
The Analysis of Varience revealed significant differences among genotypes in all
characters. In respect of vegetative growth genotype PTN recorded maximum plant height
(35.00 cm), number of leaves per clump (14.85), leaf area per plant (18.93 cm2), number of
sprouts per plant (4.25), number of rhizomes per plant (2.25), length of rhizome (12.65 cm),
width of rhizome (6.50 cm), while for all this characters GNP also showed at par result with
PTN. hi respect of sprouting percentage and weight of rhizome genotype GNP showed
significantly highest sprouting percentage (86.05 %) and weight of rhizome (141.11 g) over all
other genotypes. Observation recorded in respect of quality parameters genotype GNP recorded
maximum chlorophyll ‘a’ and chlorophyll’ b’ content (1.059 mg/lOOg and 1.613 mg/100g,
respectively). While in respect of moisture percentage genotype TKNM showed maximum
moisture percentage (77.40%). In respect of ginger oil percentage and oleoresin percentage
genotype PTN showed higher ginger oil percentage (2.47 %) and oleoresin percentage (10.05%)
over all other genotypes. In respect of yield contributing characters highest rhizome yield kg/plot
and q/ha were maximum in genotype PTN (3.41 kg/plot and 210.95 q/ha, respectively), followed
by genotype GNP (3.25 kg/plot and 200.95 q/ha, respectively). Crop duration was minimum in
genotype PTN (200 days). In respect of recovery percentage genotype GNP showed significantly
highest recovery percentage (30.35 %) over all other genotypes.
Among the five genotypes studied the PTN (3.41 kg/plot and 210.95 q/ha,
respectively), and GNP (3.25 kg/plot and 200.92 q/ha respectively), showed highest yield, which
were at par with each other. Hence, on the basis of present investigation genotype PTN and GNP
are most suitable for cultivation under Marathwada region. The findings obtained in the present
investigation need further confirmation for final recommendation.
