Online Published on 5 January, 2024. Abstract Background Local purple waxy corns, biocompound activity and nutrition content good for health, are growing from different districts and altitude of sea level in Son La province with various characters. It is essential for evaluation of agro-biological characteristics and nutritional composition of local purple waxy corns was to find out which is the best and suitable for rejuvenlination, market and production in Son La province. Methods Field experiment was conducted following scientific principle of agricultural research and designed with random completed block design (RCBD) with three replications, a 20 m2 block area. Observations and quality analysis of main traits of 12 purple local waxy corns were analyzed in summer season of 2022. Result Results showed various data of agro-biological characters, yield and biochemical kernel characters of twelve local purple waxy corns. SM8 local purple waxy corn variety showed the best agro-biological characters such as soluble protein 6.25 mg/g, total phenol 4.12 mg/g, chlorophyll stable index 89.5%, yield about 3.96 tons/ha, quality grain with starch content 68.63%, protein content 8.53% and anthocyanin content 315.03 mg/100 g. This variety can be a good option for the farmers to produce a variety with higher yield and good agro-biological characteristics.
