Conteúdo: |
Varieties of common wheat (Triticum aestivum L. em. Thell.) of low wheat–rye crossability showed increased seed set if pollinated with cultivated rye (Secale cereale L.) before the wheat spike attained maximum receptivity to wheat pollen (before the stage of first anthesis). After first anthesis the development of hybrid seed progressively deteriorated with increasing lateness of pollination. Premature or 'bud' pollination may be a useful approach for overcoming intergeneric cross-incompatibility barriers in the Triticineae. |
