Description
Resulting from extensive efforts of breeding, our new registered varieties of forage crops show excellent performance in forage production under proposed areas of recommendation, but in general there are problems for seed production. In order to raise seed production or to find out better environments a regional seed production trial including several forage species was attempted. Under wide range of natural conditions, plant characteristics especially panicle and seed properties were recorded besides seed yield for two to three harvest years. Because response of these traits in relation to environmental conditions of experimental sites was of primary concern, soil conditions and climatic records were assembled. As a result of multiple regression analysis of seed production characteristics onto environmental conditions using relational data base technique, two registered tall fescue varieties YAMANAMI and HOKURYO were closely examined. Clean seed yield and other related characters were in very close relationship with groups of several different climatic features. Environmental responses of these varieties observed in seed production traits were compared in detail, and possible measures to augment efficiency of seed multiplication were suggested.
