“…On the second hand, Cetropic and Hojancha C2008 reproduction materials show the lowest mean total height, mean DBH and mean growing stock when comparing all of reproduction materials. These results confirm Narayanan et al (2009) which prove a significant dependence of growth characteristics and timber quality on heredity.…”

Cette étude s’est déroulée dans une plan- tation forestière en Amérique centrale, proche de la ville de Diriamba au Nica- ragua, où des plantations de teck sur 48,9 ha, dans une zone de reboisement de 76,5 ha, sont renouvelées depuis 2006 (2006 : 7,90 ha ; 2007 : 13,63 ha ;2008 : 11,93 ha ; 2009 : 12,87 ha ; 2010 :21,70 ha). Cette plantation sort de l’ordi- naire du fait de l’espacement de 1 x 1 m des arbres et des facteurs écologiques limitants de cette zone tropicale aride. L’espacement de 1 x 1 m a été choisi pour favoriser la croissance en hauteur et obtenir ainsi des tiges de haute taille, et pour limiter les ramifications afin d’éviter la formation de houppiers importants. Cela permet de démarrer une production de poteaux de teck, adaptés à certaines constructions, dès la première coupe d’éclaircissement. Les paramètres de croissance des tecks (hauteur, circonfé- rence) ont été mesurés dans les placettes expérimentales mises en place en 2011. Des données complémentaires (morta- lité, arbres cassés ou tordus) ont égale- ment été relevées. Une méthodologie de terrain a été développée et les résultats restitués sous forme de tableaux et gra- phiques. Une évaluation statistique des paramètres de croissance a été menée à partir des mesures prises sur les placettes expérimentales délimitées dans la planta- tion. Les jeunes arbres plantés la même année ont été comparés selon leur prove- nance en termes de hauteur, de circonfé- rence, de productivité et de mortalité. Au total, 10 955 arbres sur 143 placettes ont été mesurés. Sur ces peuplements de 1 à 5 ans d’âge, le bois sur pied total est estimé à 1 287,89 m3, la masse moyenne de bois à l’hectare à 17,89 m3, la hauteur moyenne des peuplements à 3,03 m et la circonférence moyenne à hauteur de poitrine à 2,74 cm. Les arbres cassés représentent 5,64 %, les arbres tordus 5,66 % et la mortalité moyenne s’établit à 21,48 %.

“…Heritability of 0.27 is low for HWP but similar in families of T. grandis of similar age (MURILLO and BADILLA, 2004). But NARAYANAN et al (2009) found high heritability (Ĥ 2 = 0.77) in the HWP for 27 year old trees. Nonetheless, this low heritability found in our study or those obtained by CALLISTER and COLLINS (2008) in 4-year-old T. grandis should be taken with great caution.…”

“…Although these are considered to be low, they are relevant for the manifestation of character for future "ramets" (CALLISTER and COLLINS, 2008). In a study with clones of 3.5 years old T. grandis, CALLISTER and COLLINS (2008), SWAIN et al (1999) and NARAYANAN et al (2009) have found a value of Ĥ 2 of 0.28, 0.38 and 0.34, respectively for tree height, which authors considered low but relevant. But SWAIN et al (1999) found too high Ĥ 2 with 12 years old trees.…”

Early genetic evaluation of morphology and some wood properties of Tectona grandis L. clones

An early genetic evaluation of morphology and wood properties of Tectona grandis L. (teak) used two 4-yr-old trials with 36 clones x 3 blocks x 1 ramet (216 trees). Morphologic traits (breast height (DBH), heartwood (HWP), tree height) and some easily measured wood properties (specify gravity, tangential, radial and volumetric shrinkage; growth strain, and dynamic elastic modulus measured in standing tree, in logs, in green lumber and in dried lumber) were evaluated to establish clonal variations and their heritabilities. The broadsense heritability (Ĥ 2 ) is greater than 0.3 for DBH, radial and volume shrinkage, growth strain and dynamic elastic modulus of standing trees and logs. DBH and tree height were not genetically correlated with any wood properties, although DBH was genetically correlated with tree height and the dynamic elastic modulus in dried-lumber. According with above results, the evaluation of heritability and genetic control of wood properties is limited when it is evaluated in the juvenile stage of T. grandis clones. However morphology (DBH and tree height), and two wood properties (radial and tangential shrinkage) and the dynamic elastic modulus of dried-lumber present opportunities in the heritability or genetic control values in juvenile and they can be introduced in the genetic program.Key words: early evaluation, correlation genotypic, heritability. IntroductionTeak is a tropical species that is widely planted in Costa Rica (PÉREZ and KANINNEN, 2005). It is a species with potential to produce high quality wood (BHAT, 2000;BHAT et al., 2001) because of its good physical and mechanical properties (MOYA and PÉREZ, 2008) and color, which set market acceptance (TEWARI, 1999; THU-LASIDAS et al., 2006;ZOBEL and SPRAGUE, 1998). In clonal plantations wood quality is influenced by intensity of management and correct selection of clone phenotypic characteristics (height, diameter, and morphology) (GAL-LOWAY et al., 2001; PÉREZ and KANINNEN, 2005).Traditionally morphological characteristics of trees, such as diameter and height have been used as the main predictors of individual internal characteristics (ZOBEL and VAN BUIJTENEN, 1989;ZOBEL and SPRAGUE, 1998). In recent years, the genetic selection of plus trees have been used for wood properties selection (CALLIS-TERY and COLLINS, 2008).General evaluations of wood properties are limited and restricted to trees over 8 years old (BHAT and INDIRA, 2005;INDIRA and BHAT, 1998; RAO and SHASAHIKALA, 2003; NANARAYAN et al., 2009). However, assessments at an early age (PANDE and SINGH, 2005;SOTELO et al., 2007a and2007b;WEBER and SOTELO, 2008) using non-destructive techniques (GRABIANOWSKI et al., 2006;LINDSTROM et al., 2004;MOYA and MARÍN, 2011;SOTELO et al., 2007a) should permit genetic evaluation without inhibiting tree growth.Assessment of wood properties, their correlation with morphological characteristics and changes as the tree gets older (GOH and MONTEUUIS, 2005;SOTELO et al., 2007a and2007b) are needed to determine the best age for gene...

“…Domestication and tree improvement were initiated in Thailand, India and Indonesia in the 1950s and 1960s and was followed up based on comprehensive selections of superior plus-trees in these countries (Keiding et al 1986;Kjaer and Foster 1996;Kaosa-ard et al 1998). Since then, improvement activities have been initiated in many countries (Kjaer et al 2000), and genetic parameters estimated based on progeny and clonal trials in general predict good response to breeding (Mandal and Chawhan 2005;Callister and Collins 2008;Narayanan et al 2009;Callister 2013).…”

Twenty-nine provenances of teak (Tectona grandis Linn. f.) representing the full natural distribution range of the species were genotyped with microsatellite DNA markers to analyse genetic diversity and population genetic structure. Provenances originating from the semi-moist east coast of India had the highest genetic diversity while provenances from Laos showed the lowest. In the eastern part of the natural distribution area, comprising Myanmar, Thailand and Laos, there was a strong clinal decrease in genetic diversity the further east the provenance was located. Overall, the pattern of genetic diversity supports the hypothesis that teak has its centre of origin in India, from where it spread eastwards. The analysis of molecular variance (AMOVA) gave an overall highly significant F st value of 0.227-population pairwise F st values were in the range 0.01-0.48. Applying the G″ st differentiation parameter, the estimated overall differentiation was 0.632, implying a strong genetic structure among populations. A neighbour-joining (NJ) tree, using the pairwise population matrix of G″ st values as input, contained three distinct groups: (1) the eight provenances from Thailand and Laos, (2) the Indian provenances from the dry interior and the moist west coast and (3) the provenances from northern Myanmar. The provenances from southern Myanmar were placed close to the root of the tree together with the three provenances from the semi-moist east coast of India. A Bayesian cluster analysis using the STRUCTURE software gave very similar results, with three main clusters, each containing two sub-clusters, while Bayesian cluster analysis in the Geneland software, exploiting the spatial coordinates of the provenances, resulted in five clusters in accordance with the former results. The implications of the findings for conservation and use of genetic resources of the species are discussed.
