The mean acidity of fruit is 0.13 with a reducing sugars content of 12.8 per cent, non-reducing sugars of 3.94per cent, total sugars of 16.95 per cent and total soluble solids of 23.10 per cent.
 Approximately fruits take six months from fruit set to harvest, with two bearing seasons (December – February and May-June). The yield is 175 kg per tree or 11.8 tonnes of fruits per hectare per year at the rate of 67 trees planted at 40 feet spacing.

CO 3
(2000)

It is a hybrid between Cricket Ball and Vavilavalasa released from Department of Fruit Crops, Horticultural College and Research Institute, Coimbatore. The trees are intermediate stature with compact canopy. Highly suitable for high density planting. It bears fruits all through the year with a peak during February-June and September-October. A well-grown tree yields up to 157kg of fruits as against 109.5 and 101.32kg/tree by CO.2, CO.1 respectively. Under high-density planting system it yields 40-50t/ha. It is suitable for growing in plains up to an elevation of 100m MSL under wide range of soil conditions.

PKM 1
(1981)

It is a clonal selection from Guthi. A mean yield of 3547 fruits (236kg) can be obtained per tree per year. The tree is dwarf and adaptable to Southern and Central districts. Fruits are of two shapes viz., round (rarely) and oval (maximum). The skin is very thin and the pulp has a buttery consistency. High average yielder with medium size fruits. Average fruit weight is 100g.

PKM 2
(1992)

PKM.2 (H-2/4) is a hybrid between Guthi and Kirtibarthi varieties. This hybrid is a high yielder recording a mean yield of 80kg of fruits/tree in during fifth year after planting. The yield increase is 42.76per cent over PKM.1 variety. The fruits are bigger in size (95g) as compared to PKM.1 (84.0g). They are oblong to oval shaped. The fruits are of good quality with higher TSS (26.3°brix), total sugar (14.25%), reducing sugar (9.46%) with high sugar/acid ratio.

PKM.3 (1994)

It is a hybrid between Guthi x Cricket Ball. The variety is adaptable to tropical plains of Tami Nadu and yields 14t/ha. The fruits bear in clusters with oval shaped large fruits. The vertical growth habit of tree allows high density planting. The fruits mature earlier than other varieties in this season thus fetching higher return. The variety is tolerant to leaf spot and leaf webber.

PKM (Sa) 4 (2003)

It is a open pollinated clone of PKM 1. It is a high yielder with compact canopy and cluster bearing character. It bears spindle shaped fruits suitable for dry flakes production. The fruit contains attractive pulp with light pinkish honey brown colour which are crisp with sweet with TSS of 24 -25º Brix. The fruits are also found to be less seeded (2-3 seeds only). The best season for planting is June – July and October – November. It yields about 20.8 tonnes / hectare (100.4 kg/tree/year) which is 138.29 per cent increase over PKM 1. it is suitable for varied soil types of tropical conditions.

PKM (Sa) 5 (2007)

It is a selection from open pollinated seedlings maintained in a private orchard at Virudhunagar. Leaves are waxy, narrow, small, upright and arranged in whorl form in cluster and rich in proline content, relative water content, epicuticular wax and chlorophyll stability index.  High yielder, High Total Soluble Solids (25.50 brix) and suitable for preparation of dry flakes, milk shake powder and mixed fruit jam. Suitable for vertisols, water stagnated and drought areas. Oval shaped attractive fruits with smooth, light brown skin which facilitates a good market appeal. Flesh is crisp and retains coppery brown colour while other sapota varieties turn dark brown after ripening. Since the fruits are heavier with coloured flesh than other varieties, it is highly suitable for making flakes, powder and mixed fruit jam. It shows field tolerance to leaf spot and leaf webber incidences. This can be best planted during June – October. This is having a yield potential of 18.70 t/ha which is 19.06 % yield increase over (PKM 1) and 17.97 % (PKM 4). This is well adapted to the vertisol soils of Southern Tamil Nadu and water stagnated and drought prone areas.
