“…The most productive ten trees produced more than 30% of total seed and pod productions in the populations. Large differences were also reported for reproductive characteristics within population, among populations and years in different tree species (i.e., Keskin, 1999;Nikkanen ve Ruotsalainen, 2000;Bila, 2000;Almqvist et al, 2001;Hannerz et al, 2001;Kang et al, 2003;Bilir et al, 2003Bilir et al, , 2005Bilir et al, , 2006Bilir et al, and 2008. The differences showed importance of individual selection instead of mass selection for breeding purposes such as domestication in the species.…”

This study was carried out in three natural populations of Carob tree (Ceratonia siliqua L.) to determine the difference and interaction for reproductive and growth characteristics among populations and within population based on tree height, diameter at base, crown diameter and age, and number and weights of pod and seed for two consecutive years (2013&2014).Large differences accordance with results of analysis of variance was found among populations and within population, and also between years for reproductive and growth characteristics. Averages of reproductive characteristics were higher in first year than that of second year. For instance, weight of pod was between 9.8 kg and 59.9 kg in a population in first year, while it was between 8.1 kg and 65.2 at the same population for second year. Weights of pod were 3.9 kg and 2.3 kg in polled populations for first and second year, respectively. The most productive ten trees produced more than 30% of total seed and pod productions in the populations. The relations among the characteristics changed for the years and populations.

“…Many studies have considered all seed properties to be offspring traits (e.g., Byers et al, 1997), and accordingly have interpreted the seeds of each mother plant as half-sibs (e.g., Carles et al, 2009). In most of these cases, including almost all the studies reporting heritability for seed mass in conifer trees (Matziris, 1998;Bilir et al, 2008;Sivacioglu and Ayan, 2008;Carles et al, 2009), the reported heritability estimates were, in fact, clonal repeatability estimates. The statistical analyses used have not accounted, however, for the fact that seeds of a given mother plant are, indeed, non-independent repeated measures within the same subject (Carles et al, 2009).…”

“…Such experimental approaches are difficult to implement, especially in long-lived plants such as conifer trees , and this may explain why there are no previous studies reporting narrow-sense heritability for seed traits in long-lived trees, in which these confounding factors are properly accounted for. Previous studies with conifer trees have reported total genetic variation for seed traits (without distinguishing additive and non-additive variance) but failed to differentiate the effect of the maternal genotype from that of the maternal environment (Matziris, 1998;Castro, 1999;Roy et al, 2004;Bilir et al, 2008;Carles et al, 2009). Taking advantage of a long-term experimental device of common garden tests established within a tree breeding programme, in the present paper, we were able to properly differentiate these factors and accurately estimate narrow-sense heritability of seed traits of Maritime pine.…”

Quantitative seed provisioning is an important life-history trait with strong effects on offspring phenotype and fitness. As for any other trait, heritability estimates are vital for understanding its evolutionary dynamics. However, being a trait in between two generations, estimating additive genetic variation of seed provisioning requires complex quantitative genetic approaches for distinguishing between true genetic and environmental maternal effects. Here, using Maritime pine as a long-lived plant model, we quantified additive genetic variation of cone and seed weight (SW) mean and SW within-individual variation. We used a powerful approach combining both half-sib analysis and parent-offspring regression using several common garden tests established in contrasting environments to separate G, E and G Â E effects. Both cone weight and SW mean showed significant genetic variation but were also influenced by the maternal environment. Most of the large variation in SW mean was attributable to additive genetic effects (h 2 ¼ 0.55-0.74). SW showed no apparent G Â E interaction, particularly when accounting for cone weight covariation, suggesting that the maternal genotypes actively control the SW mean irrespective of the amount of resources allocated to cones. Within-individual variation in SW was low (12%) relative to between-individual variation (88%), and showed no genetic variation but was largely affected by the maternal environment, with greater variation in the less favourable sites for pine growth. In summary, results were very consistent between the parental and the offspring common garden tests, and clearly indicated heritable genetic variation for SW mean but not for within-individual variation in SW.
