Seed set for Scots pine clones is difficult to predict Dag Lindgren 1 Yordan Tellalov 2 and Finnvid Prescher 3 1Department of Forest Genetics and Plant Physiology Swedish University of Agricultural Sciences SE ,Umeå, Sweden 2 Department of Dendrology and Forest Tree Breeding The Czech University of Agricultural Sciences Prague, Czechia 3 Svenska Skogsplantor AB, Seed production, SE Lagan, Sweden Main problem: Can clones be selected based on predictions of seed set ability? Reply: No Predictions based on observations in a clone bank and plus trees in forest was compared with performance in seed orchards.

Umeå Plus trees The study concerns plus trees from the four northernmost counties (BD, AC, Z and Y). The first batch of plus trees were selected in natural mature forests and grafted at Umeå (Sävar). Cone set of the plus trees was usually commented. The plus tree W 4009 is the reproductively most successful tree in Sweden and perhaps Europe. It has currently about 70 million offspring in Swedish forests Sweden with current pine seed orchard zones color-coded. Figure based on a SkogForsk figure Figure based on SkogForsk photo

Clone bank (clone archive) Sävar (close to Umeå). Established clones. 4 grafts per clone in rows. 555 grafts/ha Cone-set on each ramet was registered A purpose was to avoid bad cone-producers for seed orchards The clone bank 2006 How it may have looked 1984 Photo: Yordan Tellalov

Clone bankPlus trees Correlation – mean Gain potential – mean-2.6 %-4.2 % Gain potential –weighted mean 8.9 %-5.1 % Average correlations was close to zero. Genetic gain in seed set was predicted by raising cone-set one standard deviation in clone bank or among plus trees. The gain was negative, or at least not large. The main results are based on observations in Scots pine in northern Sweden a single year in a young clone bank. More data would be desirable for generalization.

No single significant relationship. The correlations seem low. The gain in seed production if clones are selected for cone-set is uncertain and seems quite low. This study does not support to make efforts to predict seed-set before placing clones in seed orchards. Suggested Main Results

This study is based on an undergraduate diploma work: Tellalov, Yordan (2006) Relative female reproductive output of grafted Scots pine (Pinus sylvestris) clones planted on different places. More extensive acknowledgements are found there. Dag Lindgren was supervisor. Much of the data were collected and compiled for the planned PhD thesis of Finnvid Prescher.
