In addition, there was a remarkable decrease in the fruit firmness. It was assumed that cultivars with good fruit quality, especially fruit firmness would display a high adaptability to forcing culture under high temperature conditions. A convenient screening method for resistance to Anthracnose by petiole dip inoculation was developed. Using this method, the parental lines which exhibited a very strong resistance to Anthracnose could be bred. These lines were resistant not only to anthracnose but also to Fusarium wilt and powdery mildew. In a new aromatic line obtained by interspecific hybridization of F. x ananassa (8X) cv. Toyonoka × F. nilgerrensis (2X) var. Yunnan, the yield and fruit quality were close to those of the cultivar. When the interspecific hybrid line was backcrossed to the cultivar, fruit characters such as skin color and firmness improved while the aromatic character was maintained. A new storage system for strawberry genetic resources in small tests tube at a low temperature, which dose not requires subcultures, was developed. It was considered that the new storage system was highly suitable for the preservation of strawberry genetic resources in the warmer temperate region, because many germplasm accessions could be preserved safely and conveniently in a small area with minimum labor.}, pages = {37--95}, title = {日本の温暖地域におけるイチゴ促成栽培の安定化と適性品種育成に関する基礎的研究}, volume = {1}, year = {2002}, yomi = {ノグチ, ユウジ} }
