^All 22 of the groups of half-sib lines except those Kith the footnote contain one wind-pollinated line. 



^In some columns, the base number with which the column total should be compared is given following a slash (column 10, 11, 18-20). 

 This base number may be reduced from the number given in a preceding applicable column (e.g., 946 in columns 10 and 11 rather than 1P14 from 

 column 4). Reduction occurred because certain data pairs (Sj's vs. half-sibs of the same mother-tree line) were not compar.ibl c- - al 1 Sj's 

 died before producing strobili (lines 18, 37, 45, and 70), neither Sj's nor half-sibs bore male strobili (line 611, or whei total nurber 

 of strobili per tree was less than 1 (lines 61 and 65). Incomplete observations in some half-sib lines also reduced the number of cata 

 pairs (column 18, 19). 



For five of the 17 half-sib data pairs observations were missing on closed and overwintered conelets. Consequently only 12 data 

 pairs could be used to compute periodic percent losses and the differences in losses between Sj and half-sih lines. For the 12 d.ita 

 pairs. Si strobilus loss (sum of periodic losses) totals 82.5 percent, vs. 78.0 percent for the 17 pairs. Half-sib strohilns loss 

 totals 33.0 percent, vs. 39.0 percent for the 17 pairs. 



*Mean of difference significant at 5 percent level of probability, paired "t" test. 



**^!ean of difference significant at 1 percent level. Where differences are expressed in percent, the analysis was made usini; pt rcc nt s 

 transformed into angles = arcsin y^ercent.
