Description
In order to know the heritability of B-ring modification of anthocyanins in grape skin, anthocyanin composition in F_1 genaration of grape cultivars were investigated ‘Muscat of Alexandria' which has green fruit color, had latent ability of methylation for B-ring of anthocyanin.‘Ioalia' was seemed to suit as parent for breeding of red grape cultivars, be cause of its low heritability of hydroxylation ability. The heritability of methylation ability in ‘Mills' showed lower than in ‘Rizamat' or ‘Muscat Hamburg'. The amount of metylated anthocyanin in ‘Muscat Hamburg' was almost same as ‘Queen', but former cultivar seemed to have higher heritability of methlation ability than latter.‘Muscat Hamburg' had low heritability of hybroxylation for B-ring of anthocyanin.‘Schuylar' showed high heritability of hydroxylation.
交配によって得られたF_1のブドウ果実の果皮アントシアニン組成を調査し,アントシアニンB環の修飾能力の遺伝性を推察した.'Muscat of Alexandria'はアントシアニンB環のメチル化に関して潜在的な能力があった.'Italia'はアントシアニンのヒドロキシル化に関して遺伝的能力が低く,赤色品種の育成を行う場合の交配親に適すると思われた.また,'Mills'は'Rizamat'や'Muscat Hamburg'よりもアントシアニンのメチル化に関する遺伝力は低かった.'Queen'と'Muscat Hamburg'はメチル化アントシアニンを同程度含むが,その遺伝力は'Muscat Hamburg'の方が高かった.また'MuscatHamburg'ではアントシアニンのヒドロキシル化に関しての遺伝力は低かった.'Schuyler'ではアントシアニンのヒドロキシル化に関する遺伝的能力は高いと思われた.
