A biodiversity portfolio approach to buffer against unpredictable environmental change in the Northern hills of Chhattisgarh state. Four cell analysis were used to assess the amount and distribution of crop diversity within farming communities. High number of native varieties were found under the class of fewer households in small area and some varieties were found endangered due to lacking farmers' choice. Diversity indices were used to analyse richness and evenness at the target site. Sonhat site (0.677) found more diverse than batauli Simpson’s index (0.383). There are some defects in native varieties as very late maturity (>150 days), tall stature (> 140cm) prone to lodging and low yielder.
