Because N972 would have segregated for genetic male sterility and self-fertility
and pollination was not controlled within the isolation chambers, N372 could have been composed of [S.
Because dipterans are the most common visitors and they do not forage from flower to flower (Faegri and van der Pijl, 1971), self-fertility
would (1) allow seed-set in the absence of those insects that would more effectively transport pollen between plants through multiple visits in a single foraging flight and (2) possibly provide a measure of reproductive isolation for the self-fertile, self-pollinating C.
In addition, autotetraploid forms of bluebunch have increased levels of self-fertility
(Jensen et al.
Plant breeders have successfully selected for increased self-fertility
in cultivars of several predominantly outcrossing species (Villegas et al.
1] hybrids must be transmitted and retained in the backcross generations that are produced by backcrossing with jointed goatgrass until partial self-fertility
Crested wheatgrass has low self-fertility
and high levels of inbreeding depression, and additional resources required to produce and evaluate [S.
8] generations were made for height, stalk quality, self-fertility
, and tolerance to excess water conditions as lines and in hybrid combinations.
has not been tested, but both L53 and L19 are self-fertile and this character may be segregating in SR96.
Crowne is uniform in growth expression, genetically stable (2n = 4x = 40), flowers prolifically, but has low self-fertility
Palisades is uniform in growth expression, genetically stable (2n = 4x = 40), and has low self-fertility
Population 912 was developed at Salines and segregates for self-fertility
, genetic male sterility, and resistance to rhizomania.
No significant difference in self-fertility
or female cross fertility was found between the fall- and spring-sampled plants in either population.
