a greater amount of additive genetic variance between lines and permit backcrossing for the transfer of desirable traits. Large number of inbred lines of popular cassava varieties and elite clones developed at Central Tuber Crops Research Institute, Thiruvananthapuram, Kerala were screened for desirable traits and used in heterosis breeding programme. Promising backcross hybrids were developed from elite inbred lines as well as two advanced backcross lines of an interspecific hybrid of cassava with Manihot tristis having higher crude protein (8-10%) on dry weight basis in their roots. The clones exhibited high variation for crude protein in tubers with a range of 1.11% - 10.40% and 0.37% to 2.74% on dry and fresh weight basis respectively. Of the sixteen high protein clones, four clones viz. CPH-75, CPH-105, CPT-88, CPT-109 had crude protein at levels of >2.0% (fresh weight basis). Crude protein content of cassava had high significant negative correlations of -0.4812 and -0.4741 with dry matter and starch contents respectively. Present study revealed high variation for root dry matter (7.57%-49.60% ) and starch content (4.01%-42.00% ) among inbred lines (S2 ) of elite cassava clones. Highly significant positive correlation of 0.8187 was observed between dry matter (DM) percentage and starch in the clonal populations. Not Available |
