CROP IMROVEMENT AND RECENT
ADVANCES IN SAPOTA
PRESENTATION ON

2. INTRODUCTION
Common name : Sapota (Chiku, Sapodilla plum, Bully)
Botanical name : Achars zapota / Manilkara achras
Family : Sapotaceae
Chromosome : 2n = 26
Origin : Mexico and Central America
Edible part : Mesocarp
Fruit type : Fleshy berry

3. Basic Information
Commercial cultivation of sapota was first taken up in Maharashtra during
1898 in a village named Gholwad (Cheema et al., 1954).
Propagation of sapota by inarching using Rayan as rootstock is most
accepted and commercial method
For uniform or rapid ripening Ethephon (1000 ppm) can be utilized at 200-
250C
Central leader system of training is most common method in sapota
Square system of planting is recommonded in sapota.
 It is a delicious fruit introduced from tropical America.

4. Important Uses
Sapota when fully ripe is eaten as dessert fruit along with
skin, as skin is more nutritive than pulp (Gopalan et al., 1981).
Fruit is good source of digestible sugar (12-18%)
The unripe fruit and bark yield white latex, which solidifies on exposure
to air, and this forms the base material for making chickle (chewing gum)
The ripe fruits are used for making mixed jams, jelly, sherbet and halwa.
It is also used for manufacture of industrial glucose and pectin.
Its wood is used for making agricultural implements, building
construction, furniture etc.
 The bark of sapota is used as a tonic, astingent and antipyretic
 Its tender leaves are used as a vegetable.

6.  India is one of the largest producers of sapota in the world.
In India, Sapota covers 107.2 thousand hectares with annual
production of 1284.6 thousand MT and productivity of 12.0 MT/
Ha (Horticultural Statistics at a Glance 2017).
 In India, Karnataka is leading sapota producing state.
Followed by Gujarat, Tamil Nadu, Maharashtra, Andra
Pradesh and West Bengal.
Present Scenario

8. Breeding Objective:-
Dwarf structure of tree
Precocity in bearing
High yield and good keeping quality
Thick skinned, hard fleshed varieties with sandy or gritty texture are
considered low in quality
Synchronized flowering
Thus, high quality fruit combined with high seedlessness and extended
storage life are major breeding objectives
Resistance to leaf spot diseases
Salinity and drought tolerance
Kallipatti produces higher yield and better quality fruits and uses as better
parent in breeding programme

9. A center of diversity is an area that has a high degree of genetic
variation for a particular species or genus of plants that can also be the
center of origin for that species.
Sapota is a native of Mexico and Central America.
Sapota is grown on commercial basis in India, Philippines, Sri Lanka,
Mexico and Venezuela.
Centre of Diversity

10. Botany
Sapota plants are ever green in nature
The tree canopy has four kinds viz, erect growing habit, drooping
branches habit, spreading branches with sweet fruits and spreading
branches with inferior fruits
Tree can grow up to 8 m high
Fruit bearing is on new growth in axils of leaves
Leaves are elliptic to obovate, flowers solitary in leaf axils
Fruit is a drupe, egg shaped and round

11. It is wind pollinated crop
Flower type : Protogyny
Stigma grow out of the bud about 2 days before anthesis
Anthesis time : 4 – 4.30 A.M.
Anther dehisces between: 8.00 – 10.00 P.M.
The stigma become receptive 2 days before opening and continues to be
like that up to 12 hrs. after opening
Peak receptivity between: 8.00 – 10.00 A.M.
Flowering time : Tropical climate - July - Nov. and Feb - March
: Sub tropical climate - Oct - Nov. and April – May
Time taken fruit to maturity: N.I. = 10-12 months
S.I. = 4-5 months
Floral Biology

12. Morphology of Flower
The flower (about 1 cm in diameter) are solitary and peduncles on
short pedicels (1-2cm) and are carried in the leaf axils of terminal
leaf clusters
Calyx, consist of 6 sepals is arranged in 2 whorls of 3 sepals. Each
slighted connected at the base.
The outer sepals are brownish in color
Flowers are protogynous.
Corolla is consist of 6 pale white petals, which form
a bell shaped tube

13. Staminate flower Pistilate flower
•Androecium consist of 12 stamen
arranged in two whorls of 6 each (6
petaloid stamenoid and 6 stamens)
on the rim of the corolla tube
(epipetalous)
•The filaments of stamens are
short and dorsified. Anther are
small and pointed towards tip.
•Pistil is syncarpous and composed
of 4-5 fused carpels.
•There is one anthrocarpous ovule
in each locule, which is arranged in
axial placentaion.
•The style is long green and stigma
is capitate.

21. Future Thrust
Resistance against biotic and abiotic stress
Development of dwarf trait cultivars, good quality
fruit and long storage life.
Need to regularize flowering and fruit set in sapota
for a uniform development of fruits and harvest at one
time
Use of biotechnical tools in breeding programme
