“…Pandit et al (2010) also agreed with the finding that seed dissemination through this approach was rapid. Tiwari et al (2010) and Thapa et al (2009) highlighted the power of evaluating new varieties under farmers' management to greatly enhance cultivar identification based on farmers' choice, a process that leads to the selection of varieties with yield stability and ultimately provides additional benefits to farmers.…”

We conducted this research because earlier research revealed that Pakistani farmers were growing 8-10-year-old wheat (Triticum aestivum L.) varieties and hence not benefitting from the recent advances in wheat breeding. Participatory varietal selection (PVS) trials were conducted to have farmers validate and include newly released wheat varieties into seed-production stream to speed up replacement of old and obsolete wheat varieties by farmerpreferred new high-yielding varieties. Fourteen new varieties recommended for irrigated and eight for rainfed environments were evaluated in this research involving smallholder farmers in food-deficit districts of Pakistan. Collaborating farmers preferred 10 varieties from the PVS trials, eight of which were germplasm from the International Maize and Wheat Improvement Center (CIMMYT) that yielded on average 5-17% more grain than local checks. Local checks used in the PVS trials in Sindh and Khyber Pakhtunkhwa were old improved varieties. Greater yield advantage from new varieties over local checks was reported from rainfed environments and areas where old local checks were used. The PVS research showed the possibility of ensuring food security of smallholder farmers as new high-yielding varieties gave an additional 0.3 -0.5 tons of grain per ha, sufficient to feed two to three persons per year. Research also revealed that innovative farmers in rainfed regions grew wheat varieties recommended for irrigated regions to identify high-yielding wheat varieties with stable performance. Feedback by farmers to wheat breeding research system was to develop even higher yielding new wheat varieties with diseases resistance to replace old and obsolete varieties to boost food security.

“…Lilja and Erenstein (2002) describe how evidence from these approaches is important for strategic decision makers in overcoming resistance by national systems to adopt participatory research methods. Tiwari et al (2010) reported that PVS can greatly contribute to improved food security by addressing the issues of social exclusion and discrimination based on gender, ethnicity and caste and that it can have important institutional impacts in making the research and development process more inclusive and demand-driven.…”

The introduction, testing, promotion and release of a rice variety, BG 1442, in Nepal were examined in relation to existing policies governing these procedures and to how more participatory approaches could benefit food security. From 1998 to 2006, participatory varietal selection (PVS) was used to test BG 1442 and other candidate rice varieties in the spring (Chaite) rice-growing season (February to June) and in the main season (June to November). The testing of BG 1442 commenced 11 years after it was first introduced into Nepal in 1987 by the national rice research programme (NRRP). Following its initial acceptance by farmers, it was widely disseminated from 1998 by non-governmental organisations (NGOs) in the low altitude region of Nepal called the terai in projects funded by the Department for International Development (DFID), UK. This dissemination was done using a method termed informal research and development (IRD) where many small packets of seed were distributed without fertiliser or pesticides, the only additional input being a description of varietal characteristics on an enclosed leaflet. From 2001 to 2008, various assessments were made of its extent of adoption and its impact on livelihoods. In a randomised survey of households in 10 districts, BG 1442 increased from not being used at all in 1997 to being grown by about 20% of the surveyed rice farmers by 2008. It was grown both in the Chaite and the main season and was well adapted to the rainfed-upland and medium-land rice ecosystems. The variety was grown from the far west to the far east of low-altitude Nepal by resource-poor farmers. IRD was important in accelerating adoption and improving food security as it was by far the most important external source of seed for farmers. Prior to the adoption of BG 1442, farmers who did not harvest sufficient rice to last their households for 12 months increased rice self sufficiency by over 2 months (25% more). Those households that sold surplus grain and who grew BG 1442 increased grain sales by 600 kg (25% more) in the Chaite season and by 370 kg (24% more) from main season cultivation.preprintPeer reviewe

“…For example, a participatory seed selection and multiplication project in Nepal using new varieties of crops increased yields by about 45% and improved stability in household food access. A special feature of this project was that it reached poor and female-headed households and lower-caste households much better than the regular extension services (Tiwari et al 2010). Likewise, farmers in PRC, India, and Pakistan were reported to have used less pesticides and better practices after a training program on the integrated pest management of cotton.…”
