The use of quality seeds along with other inputs and appropriate cultural management practices is recognized as the most cost-effective way of increasing crop production and productivity. In considering interventions that are likely to reverse the trend of recurring food shortages, seed security has been recognized as having the potential for achieving significant advances in food productivity and production. The following technology describes the identification of local landraces of kale (Brassica oleracea) with superior cropping and disease-resistance characteristics. It also describes their development as improved varieties and the establishment and promotion of participatory seed production systems by local farmers.
