蘆筍無花青素品種育成之研究(Ⅱ)

Abstract

本試驗從倍數體間之雜交組合獲得之後代種子，播種後調查，從 2X, 3X 及 4X後代個體中初選多數無花青素品系。從 Af × Af 28 個組合之雜交中，有13個組合後代全為無花青素個體，13個組合出現 1-2株含花青素個體，有二個組合出現白苗率 16.8%，可能親本高白苗率有關。 To obtain anthocyanin-free of asparagus plants, by reciprocal crosses between diploid and autotetraploid, were conducted and processed under this hybridization test. When 28 combinations of Af × Af crosses, the progenies of 13 combinations were anthocyanin-free ( Af ), but others had more or less anthocyanin-containing ( Ac ) progenies.
