“…However, green revolution has not improved wheat production in marginal areas of the world having resource poor farmers (Sthapit et al, 1996). In order to address the problems of resource poor farmers, farmer participatory approaches were advocated by many workers (Farrington and Martin, 1988;Sthapit et al, 1994;Josi and Witcombe, 1996; Witcombe, 1996;Witcombe et al, 2003;Weltzien et al, 2003;Ashby and Lilja, 2004;Morris and Bellon, 2004;Ceccarelli and Grando, 2005;Mangione et al, 2006;Sharma and Duveiller, 2006) in selection and breeding programs.…”

Participatory varietal selection is a rapid and cost effective way of identifying farmer's preferred variety from diverse genetic material. A number of indigenous advanced wheat lines, and exotic material from CIMMYT, ICARDA and Turkey were tested using participatory varietal selection during 1998 to 2001 in the northern areas (Gilgit Baltistan) of Pakistan. Based on the farmers' preference criteria, annual workshops of field management units and combined data from 1998 to 2001, three wheat lines NR-74, NR-142 and NR-152 were selected. These lines yielded 50% more in grain and straw, and had desirable grain colour and bread making quality than local varieties. Seeds of these lines were distributed in small quantity among the village Organisations and Woman Organization for seed multiplication. The results of a household-level survey during 2007 showed that the selected wheat lines were cultivated over an area of 70% in the target area, indicating that the adoption rate of varieties was improved by farmers' participation. Participatory varietal selection approach is, therefore, suggested to adopt in resource-poor areas to develop varieties that best suit the needs of the farmers.

“…In India farmers planted sorghum varieties that were high yielding, good in quality of both grain and fodder, and resistance to biotic and abiotic stresses (Rana et al, 2000). In Mali general interest of farmers was in variety adaptation to general environmental conditions, eating quality, yield and resistance to different biotic stresses (Baidu-Forson, 1997;Sthapit et al, 1999). The quality of a variety to be used as food largely determines its acceptability by the farmers while adaptation to biotic stresses determines the survival in the field and in storage.…”

“…Initial examples of successful PPB projects tended to involve self-pollinating grain crops, such as barley and rice, in part because of the relative ease with which these crops could be bred on-farm [17][18][19][20]. After the initial crosses are made to generate variability in the breeding population, no further controlled pollinations are required in successive cycles of selection.…”

Recurrent Selection and Participatory Plant Breeding for Improvement of Two Organic Open-Pollinated Sweet Corn (Zea mays L.) Populations

Organic growers face unique challenges when raising sweet corn, and benefit from varieties that maintain high eating quality, germinate consistently, deter insect pests, and resist diseases. Genotype by environment rank changes can occur in the performance of cultivars grown on conventional and organic farms, yet few varieties have been bred specifically for organic systems. The objective of this experiment was to evaluate the changes made to open-pollinated sweet corn populations using recurrent selection and a participatory plant breeding (PPB) methodology. From 2008 to 2011, four cycles of two open-pollinated (OP) sweet corn populations were selected on a certified organic farm in Minnesota using a modified ear-to-row recurrent selection scheme. Selections were made in collaboration with an organic farmer, with selection criteria based on traits identified by the farmer. In 2012 and 2013, the population cycles were evaluated in a randomized complete block design in two certified organic locations in Wisconsin, with multiple replications in each environment. Significant linear trends were found among cycles of selection for quantitative and qualitative traits, suggesting the changes were due to recurrent selection and PPB methodology for these populations. However, further improvement is necessary to satisfy the requirements for a useful cultivar for organic growers.
