Kera Sankara (WCT XCOD)

The palm comes to bearing by the fourth year of planting. The mean annual yield of nuts is 108 with a range of 70-130 nuts. The copra content is 187g/nut. This hybrid was released by CPCRI in 1991, for large scale cultivation in Kerala, coastal Andhra Pradesh and coastal Maharashtra.

 

Kalpasree 

This dwarf variety was developed by selection made from Chowghat Green Dwarf cultivar. Kalpasree has superior quality of coconut oil, very sweet tender nut water and meat and is resistant to root (wilt) disease. This variety takes about 2.5 to 3 years for flowering. It is found to be resistant to root (wilt) disease. The mean annual yield is 90 nuts/palm with a copra content of 96.3g. This variety was released by CPCRI in 2012 for root (wilt) prevalent areas of Kerala.However, like other dwarfs, caution is advised for the control of red palm weevil.

Kalparaksha

This variety is a selection from introductions of Malayan Green Dwarf made from Malaysia and was developed through evaluation and selection. This is a semi tall variety with sweet tender nut water and with higher resistance to root (wilt) disease of coconut. It comes to flowering by 54 months from planting. Its annual yield is 87 nuts/palm, 16.38 kg copra/palm and 10.65 kg oil/palm. The quantity of tender nut water is 290ml. This variety was released by CPCRI in 2008 as a variety for tender nut and for cultivation in root (wilt) prevalent areas of Kerala

Kalpa Sankara

 This coconut hybrid was produced by crossing root (wilt) disease-free Kalpasree as female parent and high yielding and disease-free West Coast Tall as male parent. Disease-free parental palms were selected from ‘hotspots’ of root (wilt) disease. It has a semi tall stature with precocious bearing. The mean annual yield is 85 nuts per palm. The copra yield is 2.5 t/ha and oil is 1.69 t/ha. This hybrid was released by CPCRI in 2012 for cultivation in root (wilt) disease prevalent tracts of Kerala.

Chowghat Orange Dwarf (COD)

This is an early flowering cultivar and takes about    3-4 years for initial flowering. The average annual yield is 63 nuts/palm. It is best suited for tender nut water. This cultivar was released by CPCRI in 1991 for large scale cultivation as tender nut variety.

West Coast Tall (WCT)

This is local tall cultivar. In the ‘hotspots’ of root (wilt) disease, healthy and high yielding WCT palms are occasionally found. The average annual yield of the selected mother palms is 80 nuts/palm with a copra content of 177g/nut. WCT mother palms are selected after ELISA testing to confirm its disease-free status and seedlings are raised from seed nuts collected from the selected mother palms. Since the expression of resistance to root (wilt) disease and high yield are genetically controlled, the progenies of these palms are also expected to be relatively high yielding and disease-free compared to unselected seedlings of WCT.
