Seed production from hand outcrosses
and natural pollination.--Hand outcrossed flowers produced 16% more seeds than naturally pollinated flowers (Table 3).
What a difference now, when the inbreds number 123 and the outcrosses
Open-pollinated (OP1a) seed, from outcrosses
with other hypersensitive plants within each plot and with nonhypersensitive plants in adjacent plots, was collected from the hypersensitive clone plots in 1992.
Overall, mortality of selfed progeny exceeded that of outcrossed progeny in 63 of 71 families (outcrosses
exceeded selfs in 8 families: 1 in D2, 1 in T2, 4 in T4, 2 in T26), a significant difference between self and outcross treatments.
to less-fashionable bloodlines, or even to other breeds, the thoroughbred breed will continue to multiply flaws and weaknesses, which will not be in the longerterm interests of the breeding or racing industries.
) were defined as plants that differed (e.g., height, panicle shape, seed color) from the pure line phenotype.

In the article that filled this space relating to the 1996 Pattern, I noted that of the 235 successful individuals, 48 were inbred within four generations, while 43 were complete outcrosses
, showing no duplications within five.
vulgaris was highly self fertile but that occasional outcrosses
arose when black-, white- and brown-seeded beans were grown together.

Her two-year-old, by Lear Fan, and yearling, by A P Indy, are products of less radical, but more fashionable, outcrosses
, whereas her two-week-old foal, by Unbridled's Song, and her projected 2004 foal, by Kingmambo, show inbreeding to Mr Prospector.
Each diallel was constructed using two randomly chosen parental plants and consisted of four types of progeny: two sets of selfed progeny, one from each parent, and two reciprocal outcrosses
. Seeds were planted in a random design at the University of Chicago and transported to Oregon in early June 1990.
