Evaluation of yield and quality in cassava landracesvarieties towards sustainable development in Vietnam

Abstract

In Vietnam, cassava is a food crop that plays a vital role in agricultural development, ranking third after rice and corn. Currently, the conservation of cassava genetic resources is receiving increasing attention to ensure diversity and create a source of materials for the selection of varieties with stable yield and nutritional content to adapt to climate change. In particular, evaluations for yield and quality in cassava landraces in Vietnam are still limited. These are a gap in the conservation of local cassava genetic resources towards sustainable development in the future. The study focused on evaluating the yield and quality of 200 cassava accessions, the results showed that cassava accessions had an average yield of 17.2 tons/ha, ranging from 1.5 - 41 tons/ha, with 72.5% of the cassava accessions having a starch content of over 25 g/100 g, dry matter content ranged from 22.9 - 48.6 g/100 g; total sugar content ranged from 0.27 - 3.7 g/100 g, HCN content ranged from 0.45 - 248 mg/kg with an average of 17.57 mg/kg.
