Recieved Date: 2022-02-23, Accepted Date: 2022-03-20


This study aimed to screen out suitable genotypes of water chestnut based on the performance of plant growth characters, yield and biochemical properties of fresh fruit. Eight genotypes of water chestnut were grown and evaluated at the Research Centre for Makhana, Darbhanga, North Bihar, India, following randomized block design and 3 replications. Observations were taken on yield attributing characters like, no. of plantlets/plant, no. of fruit/plantlets, fruit weight, total yield and biochemical parameters like TSS, acidity, non reducing sugar, reducing sugar, sugar acid ratio, etc. There were significant results on the number of fruits /plantlet production which ranged 6.1-13.4 in 2018 and 5.92-13.96 during 2019. The maximum flowering periods of 55 and 60 days accounted for the total yield of 12.0 and 12.87 t/ha in case of Green Spineless genotypes during 2018 and 2019, respectively. On the contrary, the Red Spineless genotypes had the highest TSS of 9.6°B and 9.2°B in 2018 and 2019, respectively, and later was sweetest over Green Spineless. The Red Spineless genotype had the highest total sugar of 4.61% and 4.16% in 2018 and 2019, respectively. However, TSS: acid ratio of Green Spineless and Red Spineless genotypes were statistically at par in both the years. The Green Spineless also recorded the maximum fresh biomass to production system after decomposition. The genotype Green Spineless had wider adaptability, hardy and gave favorable yield under congenial weather of Darbhanga, in both the years while Red Spineless produced quality fruits due to its genotypic characteristics and weather effect. From the plant growth, fruit characters and nutrient recycling under the wetland ecosystem of North Bihar, Green Spineless and Red Spineless genotypes of water chestnut were promising over traditional Red Spine. Management of plant genotypes and there cultivation had immense value to increase profitability and ensure livelihood security of the farmers of North Bihar.
