Also, the complementary information that is exploited in the line-cross, half-sib and combined models can be used to obtain greater power to detect QTL and allows characterization of detected QTL in terms of their segregation within the parental breeds.
In winter 1986-1987, about 1750 plants representing the 106 half-sib lines from Cycle 3 were evaluated for galling and egg mass response when inoculated with Mi.
Demonstration of heritability is best done with comparisons of half-sib groups because they are less likely to be affected by environmental influence (Gjedrem 1992).
Resistance, defined as the complement of proportion damage, varied significantly among paternal half-sib families in the factorial ANOVA (Table 3, [ILLUSTRATION FOR FIGURE 1 OMITTED]), suggesting that the base population from which parent plants were obtained would possess heritable variation for damage in an environment with an equal probability of encountering either of the two fungal isolates used here.
Half-sib families were established on 1-m centers arranged as a randomized complete block design with four replications.

In the two half-sib matrices, rejection frequencies [Mathematical Expression Omitted]; n = 2) were generally more than double those of transitory fusion [Mathematical Expression Omitted].
These crosses result in a set of full-sib families and half-sib families.
A half-sib design mating experiment was done for initial estimates of the heritability of thorax width in each sex, as well as the genetic correlation between the sexes.
With respect to NDSABC0, response to half-sib progeny selection increased (P [less than or equal to] 0.
Additive genetic correlations among traits within each sampling time and between traits across sampling times were estimated by product-moment correlations between half-sib family means.
These 192 ecotypes were intermated and seed from the best 12 ecotypes based on seed-yielding ability were then established into a half-sib progeny performance trial to determine their grazing persistence in grass swards.
