Abstract

In cassava triploids (2n = 54) were produced by crossing the cultivated diploids (2n = 36) with induced tetraploids (2n = 72). The triploids were characterised by vigorous growth, erect plant type, broad leaves and stout stem. Besides they were also found to be significantly higher yielders than the diploids and had higher starch content. For isolating high starch clones for use in industry, a wide range of triploids were produced and evaluated at the CTCRI. One of the triploids viz. 2–14 was proved to be superior in tuber yield, starch content and especially culinary quality. The Kerala State Variety Release Committee officially released the triploid variety under the name ‘Sree Harsha’ in 1996. This is the first triploid variety of cassava developed by polyploidy breeding and released for general cultivation.
