Evaluation of exotic and indigenous coconut genotypes for nut water quality


Author(s): Tripura U and P Paramaguru

Abstract: Investigations were carried out at Coconut Research Station, Tamil Nadu Agricultural University, Aliyarnagar, during 2015-2017 to identify superior coconut genotypes for nut water. The volume of nut water content and qualitative attributes viz., pH, TSS, total sugars, reducing sugar and amino acid start declining towards the nut maturity. The maximum amount of nut water content in tender and mature nut was recorded by Andaman Giant (724.00 ml and 655.00 ml, respectively). However in tender and mature nut water, the maximum qualitative characters such as TSS (8.40 and 7.30 0Brix) and total sugars (5.89 and 5.39 g/100 ml, respectively) was recorded by genotype FMS. The free amino acid in tender and mature nut water ranged between 2.012 to 1.541 mg/100 ml and 1.890 to 1.397 mg/ 100 ml, respectively. The lowest to optimum level of sodium and potassium content in tender and mature nut water were recorded by FMS (19.62 and 19.41 ppm) followed by BSI (20.43 and 20.27 ppm). Similarly, low to optimum level of the potassium content of tender and mature nut was recorded by genotype FMS (1833.00 and 1855.28 ppm ppm) followed by BSI (1989.00 and 2012.21 ppm) and MGD (2030.00 and 2064 ppm), respectively. Hence, genotypes FMS, BSI and MGD can be utilized for further crop improvement programme with respect to nut water quality.
