Arecanut is
one of the very few examples, wherein crop improvement work
combined with improved input technologies contributed to
revolutionized production and productivity. Evolving
high-yielding and improved varieties of arecanut has been
successful through the introduction and indigenous and exotic
types and selection of mother palms, seed nuts and seedlings. In
recent years, hybridization and exploitation of dwarfing genes
for breeding dwarf and high-yielding varieties have been
initiated.Germplasm repository at CPCRI regional station, Vittal,
Karnataka, consists of 113 accessions. This includes 23 exotic
introductions from Fiji, Mauritius, China, Sri Lanka, Indonesia,
Vietnam, Singapore and Australia, representing 6 species of
Areca and 90 indigenous types obtained from different parts of
India. Screening of germplasm accessions led to released of
several high-yielding varieties, like the following:
1.Mangala: It
is an introduction from China. A semi-tall variety, it has
partially drooping crown with sell spread leaves and more number
of leaflets. The leaflets are dark green with characteristic
crinkling at the tip. It is semi tall, early-bearing with
quicker stabilization of yield and producing nuts with good
chewing and market quality. It produces nuts with good chewing
and market quality. It produces 10 kg ripe nuts/palm/year which
gives 2 kg chali.
2.Sumangala:
It is an introduction from Indonesia. Palm is tall with
partially drooping habit. Under ideal conditions, it flowers in
4-5 years. The nuts are deep yellow to orange in colour and
oblong to round in shape. It gives an average yield of 17.25 kg
ripe nuts/palm/year at 10th year.
3.Sree Mangala: An
introduction from Singapore, its habit, flowering and fruit
characters are similar to Sumangala. It gives an average yield
of 15.63 kg/palm/year.
4.Mohitnagar:
This is an
indigenous cultivar from West Bengal. The important feature of
this variety is its greater uniformity. The bunches are
well-spaced and nuts are loosely arranged on the spikes which
help in uniform development and enable efficient
plant-protection measures. Early stabilization of yield and high
annual yield potential of 3.7 kg chali/palm (15.8 kg ripe nuts)
are its characteristics.
5.Calicut:
Recommended
for Andaman and Nicobar Islands, this is tall with longer
internodes and crown. The stricking feature of this variety is
its consistent and high yield potential (18.89 kg ripe nuts/palm
years with a chali yield of 4.34 kg/palm) having well-placed
bunches with round and bold nuts.
