Chayote or Squash, locally called “Iskush” is cultivated extensively and in different varieties in Sikkim. In absence of scientific study on different NE varieties of chayote has led to limited use and less return. In this regard, proper study of physical and textual characteristics of chayote varieties may facilitate development of different processing machineries and value-added products which will enhance farmers’ income. In the present investigation, six varieties of chayote found in Sikkim were analyzed for physical properties viz., size, shape, surface area and textural characteristics viz., firmness, puncture force, toughness and cutting force using TA-HD Plus Texture Analyzer. The equivalent diameter of the selected chayote varieties varied between 53.82±4.67 mm and 88.61±4.01 mm. From the sphericity and other dimensions of the fruits, the shape of the chayote samples can be designated as oblong for LGS variety, conic for LS variety and regular for YS, GS, DGS and YLS variety. The surface area of the six chayote varieties varied in the range of 9099.68 mm2 to 24669.67 mm2. The firmness of chayote varieties varied between 42.83 ± 1.72N and 84.63±8.1 N. Puncture force varied between 36.5±2.19N and 41.29±3.42N. The toughness values ranged between 101.49 N-mm to 134.27 N-mm cutting force varied between 77.7±7.11N and 100.29±9.13N. From the results of Analysis of variance, the effect of variety on firmness and cutting force was found to be significant (p < 0.05) whereas varietal effect was non-significant (p >0.05) on puncture force and toughness.
