“…Among the www.nature.com/scientificreports/ 24 on-farm conservation sites, the age of the custodian farmers ranged from 35 to 75 years; majority (12) were in the age bracket of 40-60 years. The two young farmers (< 40 years) actively engaged in on-farm conservation were exclusively involved in commercially attractive activity of maintaining the rootstocks of traditional cultivars of perennial crops (pepper, mango and jackfruit) popular for their adaptation and resistance to pests and diseases 36 . However, it was starkly clear in our survey that younger generation of farmers is not inclined to engage in on-farm conservation.…”

“…Thus, custodian farmers play a significant role in the seed flow and they are the main source of seeds in the region. Few farmers from Shivamogga develop nursery for sale of landraces, mainly pepper, jackfruit and pickling varieties of mango 36 . Through germplasm movement, these farmers are developing a dynamic process of diversity on their farms 22 .…”

Landraces are important genetic resources that have a significant role in maintaining the long-term sustainability of traditional agro-ecosystems, food, nutrition, and livelihood security. In an effort to document landraces in the on-farm conservation context, Central Western Ghat region in India was surveyed. A total of 671 landraces belonging to 60 crops were recorded from 24 sites. The custodian farmers were found to conserve a variety of crops including vegetables, cereals and pulses, perennial fruits, spices, tuber and plantation crops. The survey indicated a difference in the prevalence of landraces across the sites. A significant difference with respect to the Shannon-diversity index, Gini-Simpson index, evenness, species richness, and abundance was observed among the different survey sites. Computation of a prevalence index indicated the need for immediate intervention in the form of collecting and ex situ conservation of landraces of some crops as a back-up to on-farm conservation. The study also identified the critical determinants of on-farm conservation, including (i) suitability to regional conditions, (ii) relevance in regional cuisine and local medicinal practices, (iii) cultural and traditional significance, and (iv) economic advantage. The information documented in this study is expected to promote the collection and conservation of landraces ex situ. The National Genebank housed at ICAR-NBPGR, New Delhi conserves around 550 accessions of landraces collected from the Central Western Ghats region surveyed in this report. Information collected from custodian farmers on specific uses will be helpful to enhance the utilization of these accessions.
