Where, [y.sub.ij] was the phenotypic record of the jth bird, originating from the ith sire; mj was the average effect for the ith half-sib family; [a.sub.i] was the allelic substitution effect for a putative QTL within the ith sire; [x.sub.ij] was the conditional probability for jth individual that could transmit a given allele from the ith sire; [e.sub.ij] was the residual.
The objective of this study was to determine the effects of genotype on seasonal trends in gas exchange parameters at the leaf and crown levels for loblolly pine varieties and half-sib families from the eastern portion of the loblolly pine range grown on a site in the western portion of the range (northwestern Louisiana).

The spawning procedure used to produce the NJ and NR half-sib families was the same as described by Ky et al.
Genetic relatedness: To evaluate the bias for relatedness towards the expected value of 0.5 for full-sib, 0.25 for half-sib and 0 for unrelated, we used three estimates of relatedness coefficients: rxyW, (Wang, 2002) rxyLR(Lynch and Ritland, 1999) and rxyQG (Queller and Goodnight, 1989).
The completely randomized design was used, where the treatments were those 29 half-sib progenies (1-29), with four replicates with 50 seeds each one.
Traits###Number of ewes (half-sibs)###Number of rams###Heritability estimates
Based on genetic component estimates (Table 3), the heritability estimates of the PE trait are in line with results obtained by Sawazaki (1996), which ranged from 60 to 90% in popcorn half-sib families.
On an experiment wide basis, all sativa genotypes exhibited within subspecies half-sib means (WHS) that were equivalent to their sativa-falcata half-sib (SFHS) counterparts except genotypes ABI311, ABI314, and ABI419 (Table 2).
The half-sib broods were produced in autumn 1994 by mating 12 males to 2 females each.
On average, nearest neighbors appear to share a relationship equivalent to at least that of half-sibs. Relative to the 1-km cross, the reduction in growth of progenies from crossing between nearest neighbors is one-third of that due to selfing (18% cf.
On each date, the experimental unit for each treatment combination consisted of the mean of nine seedlings (three seedlings from each of the three half-sib families).
