Abstract:

This experiment was carried out to study the variations among vetch landraces (Vicia sativa and Vicia ervilia) collected from Jordan. During April and May, 2007, a survey was carried out to collect vetch landraces from rainfed areas with diverse eco-geographical variation of Jordan. Twenty six landraces were assessed in the field during 2008/2009 growing season at three experimental sites (Faculty of Agriculture Research Station, Ghwier Agricultural Research Station, and Rabbah Agricultural Research Station). Results showed that there were significant variations among the three experimental sites. Grain yield, biological yield and straw yield gave the highest CV values when grown at Jubaiha experimental site. These differences could be attributed to differences in rainfall received during the growing season. The highest values for biological, grain and straw yield was obtained for accessions collected from Madaba. This variability among collection sites for the studied parameters will assist plant breeders to focus their collection of germplasm to the areas where the maximum diversity for the target character is present. There were highly significant correlation coefficients between grain yield and biological yield, straw yield, number of secondary branches per plant and number of pods per plants. Selection for these characters would improve grain yield. Cluster analysis showed that V. ervilia is mostly used by farmers from Karak region compared to V. sativa which is used in the middle and north parts of Jordan. This can be attributed to the fact that V. sativa needs higher rainfall than V. ervilia. Therefore, V. ervilia is grown in the low rainfall areas. Meanwhile, V. sativa is grown in the higher rainfall areas.
