TNAU coconut ALR 3 – a promising mite tolerant tendernut variety
Coconut water is considered as nature’s gift to mankind due to its health benefits. The steady demand for tender coconut is currently met from a local dwarf from Kerala, viz., Chowghat Orange Dwarf (COD). However, there is a need for diversification of genotypes. Based on a 20-year-old germplasm evaluation trial conducted at Coconut Research Station (CRS), Aliyarnagar, a selection from Kenthali Dwarf (KTD) has been identified as a promising genotype exclusively for tender nut purpose. It has been released as TNAU coconut ALR 3. The selection is an early flowering genotype that comes to flowering from the third year onwards. The average yield potential is 86 nuts per palm per annum from the stabilized bearing period onwards, with a maximum yield potential of 121 nuts per palm per annum. This accounts for 34.1% and 37.9 % increase in yield over COD and MYD. Tender nut water analysis revealed that the genotype possessed 5.2% soluble sugars with a high potassium level (190.21) compared to COD and MYD. The variety is recommended for irrigated belts of Tamil Nadu.
