在迪纳杰布尔孟加拉国农业研究所（BARI）小麦研究中心进行了参与式选择，以促进农民选择和推广他们的优选品种，取代广泛种植的易患疾病的Kanchan，以提高小麦产量和产量。2002年通过参与式农村评价确定了农民对小麦品种的需求，2005年通过农户水平调查评估了影响。研究是以母亲和婴儿的方式进行的。通过种子供应扩大了种子传播。BAW1008、沙塔布迪和BAW 1006在母幼试验中产量均较高，在农民总体偏好上得分较高。农民在计分过程中注重产量、粗粒白粒、多粒/穗、茎强等性状。他们鉴定出BAW 966、BAW 1006、BAW 1008和Shatabdi为优质的Chapati。他们希望在接下来的几年里培育出BAW1008、Shatabdi和BAW 1006。农民之间的种子传播非常令人满意，2004- 2005年，沙塔布迪种子达到了47%的村庄小麦农民。品种多样性显著增加，研究村共种植了7个品种。干禅的面积从2002-03年的100%下降到2005-06年的24%。与会人员对植物育种的新理念充满希望，期待其在国内得到广泛应用。DOI: http://dx.doi.org/10.3329/bjar.v32i3.549孟加拉国J.

Participatory selection was conducted at the Wheat Research Centre, Bangladesh Agricultural Research Institute (BARI), Dinajpur to facilitate farmers in selecting and disseminating their preferable variety and replace widely cultivated disease susceptible Kanchan to increase wheat yield and production. Farmers’ need for wheat variety was identified through participatory rural appraisal in 2002 and impacts were assessed by house hold level survey in 2005. Researches were conducted as mother and baby trials. Scaling-up seed dissemination was carried out through seed supply. BAW1008, Shatabdi, and BAW 1006 produced higher yield in both mother and baby trials and got higher scores for farmers’ overall preference. The farmers emphasized on yield together with bold and white grains, more grains/spike, strong stem and other characters during scoring. They identified BAW 966, BAW 1006, BAW 1008, and Shatabdi for good Chapati quality. They expected to cultivate BAW1008, Shatabdi, and BAW 1006 in the following years. Farmer to farmer seed dissemination was highly satisfactory and seeds of Shatabdi reached 47% wheat farmers of the villages in 2004-05. Varietal diversity was increased remarkably and seven varieties were grown in the study villages. The area of Kanchan came down from 100% (in 2002-03) to 24% (in 2005-06). The participating personnel were hopeful to the new concept of plant breeding and expecting its widespread use in the country. DOI: http://dx.doi.org/10.3329/bjar.v32i3.549 Bangladesh J. Agril.
