Agronomic value of spring field pea breeding lines and varietes for green forage production

Spring eld pea is one of the most important coarse legumes. In most pea breeding programs selection process is focused on development of high-yielding and top-quality varieties for gra- in and/or green forage production. Production of protein rich grain is mainly associated with spring varieties, while production of green mass rich in protein, minerals and vitamins is chara- cteristic for winter varieties. Due to problems with planting in autumn (late harvest of previous crop, heavy rains during soil preparation and planting, business plan modi cations, abundance of cattle etc.), farmers o en prefer spring pea varieties that can produce large green mass over shorter period of time, as well as ensure planting of the next crop at the same eld. Objectives of this research were: agronomic value assessment of (spring and potentially winter) varieties and new breeding lines of spring eld pea over two year-period (2012-2013), as well as selection of lines with most potential for further breeding process and/or registration of new spring eld varieties for green forage production. Highest mean yields of green mass and dry matter, as well as favorable values of other assessed traits were scored by breeding lines MBK-7, MBK-41, MBK- 51, and varieties Dora and Poneka.  ese varieties represent valuable germplasm for further breeding process, while selected lines have high potential for development of new varieties.
