Pollen Compatibility Studies with European and Japanese Plums

Abstract

‘Valor’, ‘Verity’, ‘Vision’ and ‘Vineland’ selection ‘V. 33028’ plums were completely self-incompatible. Hand pollination showed that ‘Valor’ and ‘Verity’ were cross-compatible. ‘Valor’ and ‘Verity’ set fruit satisfactorily with ‘Vision’ pollen, but ‘Vision’ did not set well when pollinized by ‘Valor’ or, ‘Verity’. ‘V. 33028’ was cross-compatible with ‘Verity’ and ‘Vision’, but not with ‘Valor’. ‘Italian’, ‘Stanley’, and ‘California Blue’ were effective pollinizers for ‘Valor’, ‘Verity’ and ‘V. 33028’. ‘Bluebell’ was satisfactory for ‘Valor’, while ‘Iroquois’ was effective for ‘Verity’ and ‘V. 33028’.

‘Shiro’ set well with ‘Reine Claude’, ‘Methley’, ‘Myrobalan B’ and ‘0-3010’. ‘Early Golden’ and ‘Methley’ were satisfactory pollinizers for ‘Burbank’. ‘Shiro’ did not fertilize ‘Burbank’. ‘Ozark Premier’, ‘Myrobalan B’ and ‘0-3010’ were good pollinizers for ‘Burbank’ and ‘Early Golden’. ‘Early Golden’ set adequately with pollen from ‘Burbank’, ‘Santa Rosa’ and ‘Woodruff’.
