  • Looking at the importance of Carambola with respect to its medicinal and nutritional value, the demand for the planting material of this underutilized fruit gradually increased. However, there is no specific recommended variety available although wide variability exists throughout the length and width of North East India, showing wide variation in fruit quality (sweet and sour), shape, sizes and yield. Moreover, these variabilities have neither been exploited nor properly documented and are grown in homestead garden or wild form. Farmers have been using planting materials of seedling origin with unknown yield potential and fruit quality. Thus, emphasizing on these facts an extensive survey was conducted in different parts of North East India (Arunachal Pradesh, Assam, Manipur and Meghalaya) during 2017-19 to study the genetic diversity of carambola using morphological and molecular marker to assess variability within the genotypes as well as to evaluate superior genotypes of Carambola having sweet taste and high yield potential based on the descriptor of NBPGR of carambola. The experimental results showed significant difference with respect to individual fruit weight, fruit length, volume of fruit, fruit yield, TSS, Oxalic Acid, Ascorbic acid and acidity. RAPD molecular marker also showed considerable variation in which out of the 20 RAPD markers used 15 primers generated 92 total numbers of band and 64 polymorphic bands with a mean of 4.26 bands per primer and 69.34% polymorphism.
