Inheritance of pseudo-self compatibility in self-incompatible garden and greenhouse chrysanthemums, Dendranthema grandiflora Tzvelv
Self incompatibility (SI) can be used to alleviate costly hand emasculation and pollination in F1 hybrid chrysanthemum seed production. SI, however, disrupts the progression of inbreedig (selfing or full-sib mati...

Congruity backcrossing as a means of creating genetic variability in self pollinated crops: seed morphology of Phaseolus vulgaris L. and P. acutifolius A. Gray hybrids
Seeds of early generations of three reciprocal congruity-backcross (CBC) pedigrees, developed by backcrossing Phaseolus vulgaris-P. acutifolius hybrids to each of the parent species in alternate generations, exhi...

Incongruity in the interspecific crosses of Vitis L. Morphological abnormalities in the F2 progeny
The F2 generation of interspecific crosses of Vitis were examined for symptoms of incongruity, manifested as morphological abnormalities in the seedlings. Dwarfing, achlorophyllic variegation, deformed leaves, ye...

Incongruity in the interspecific crosses of Vitis L. Reproductive expression in the F1 progeny
F1 progeny from three classes of crosses were studied for indications of incongruity in the form of reproductive dysfunction. Percent fruit set was found to be approximately equivalent to the additive inverse of....

Inbreeding depression in garden and glasshouse chrysanthemums: germination and survivorship
Sixty-six chrysanthemum (Dendranthema grandiflora) inbred selections, noninbred cultivars and hybrids, and D. makinoi were the base populations from which up to three generations of inbreds were obtained using mu...

Discriminating styles (DS) and pollen-mediated pseudo-self compatibility (PMPSC) in Petunia hybrida hort
Discriminating styles (DS) in Petunia hybrida discriminate among incompatible pollen sources with pollen-mediated pseudo-self compatibility (PMPSC) similarly to those in Nemesia strumosa. Both species exhibit a s...

Effect of selection for pseudo-self compatibility in advanced inbred generations of Nemesia strumosa Benth.
Highly pseudo-self compatible (PSC) Nemesia strumosa plants were selfed and intercrossed to produce progenies of the F5 through F7 generations. Though high PSC progenies were obtained, none were truebreeding. Pro...
