Article Synopsis
- On-farm conservation of crop landraces, specifically for paddy rice, wheat, and maize, is gaining attention as a way to preserve plant genetic diversity, compared to traditional conservation methods.
- A comprehensive survey conducted in Yunnan Province covered 306 villages and revealed significant loss of landrace varieties, with 44.8% of villages losing paddy rice, 77.5% losing wheat, and 37.3% losing maize.
- The survey identified a total of 901 collected landraces, highlighting great diversity in varieties across different ethnic groups, with paddy rice showing the most variability, influenced by local culture and customs.
To reveal the genetic variation of rice paddy landraces across 30 years, we compared the genetic variation of between 6 paddy rice landraces grown in Yuanyang Hani's terraced fields in Yuanyang County, Yunnan Province in the 1970s (past-grown landraces) and 6 paired ones that have been grown during the past decade (current-grown landraces) using 60 SSR markers. The results showed that one to four alleles were amplified in 60 loci and 159 alleles in all the landraces tested. The number of alleles from the current-grown landraces decreased by 7 alleles compared to the past-grown landraces.
