Genetic control of rooting ability of lodgepole pine cuttings

Fries, A
Kaya, Zeki
This study evaluates the genetic control of rooting ability ex vitro for cuttings of lodgepole pine (Pinus contorta var. latifolia Engelm.). More than 200 clones from 21 full-sib families were studied during 4 yr in the greenhouse. Clonal averages in rooting frequency, root size score, shoot extension during rooting, and vitality score were calculated, together with variance components and phenotypic and genetic correlations among variables. Years, families within latitude of origin, clones within families within latitudes, and cutting type (type of shoot used as cutting) had statistically significant effects on rooting traits of cuttings. Years and clones within families had significant effects on height increment. Broad-sense heritabilities of clonal means were 0.55 for rooting frequency, 0.66 for root size, 0.56 for height increment, and 0.34 for vitality. To reduce the nongenetic variation when estimating genetic parameters, cuttings should not be taken from different shoot types. Genetic correlations among the variables were generally negligible. Cutting propagation of lodgepole pine seems possible for producing plants for genetic tests. After refinement of the methods it may also be used operationally, but clones that produce few shoots and have low rooting ability might be lost.

The pattern of inheritance of genes conferring resistance to malathion and genetic consequences of linkage between an autosomal male-determining factor and resistance genes on the second chromosome were investigated in a strain of house fly, Musca domestica L., selected for malathion resistance. The second and fifth chromosomes contribute significantly to malathion resistance. The presence of a male-determining factor linked with the resistance genes on the second chromosome resulted in a strong sexual dimo...
Genetic differentiation of Abies equi-trojani (Asch. & Sint. ex Boiss) Mattf. populations from Kazdaǧι, Turkey and the genetic relationship between Turkish firs belonging to the Abies nordmanniana Spach complex
Kaya, Zeki; Neale, David Brian (2008-02-05)
The present study aimed to test the utility of RAPD (randomly amplified polymorphic DNA) and cpSSR (simple sequence repeats) markers for in situ gene conservation programs for fir species, as well as for determining the genetic similarities between the Abies nordmanniana Spach species complex (A. nordmanniana, A. bornmuelleriana Matff., A. equi-trojani (Asch. & Sint. ex Boiss) Mattf.) and between populations of A. equi-trojani, which is a narrow-endemic to Turkey. For this purpose, DNA was extracted and poo...
Genetic structure of black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled from the Bolkar Mountains
Tolun, AA; Velioğlu, E; Çengel, Burcu N; Kaya, Zeki (2000-01-01)
In order to determine the magnitude and pattern of genetic diversity among Anatolian Black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled in Bolkar Mountains and to recommend the potential populations which may be suitable for in situ conservation of genetic resources in this species, isoenzymes from 14 enzyme systems were investigated by starch gel electrophoresis. For this reason, open pollinated seed megagametophytes of half-sib families originated from the four populations (Camliyay...

Genetic variation of honey bee populations from 9 different locations of Bulgaria was studied using 4 enzymic systems (MDH, ME, EST and ALP) corresponding to 4 genetic loci and PCR-RFLP's analysis of 16s rDNA, COI, and ND5 gene segments of mtDNA. Allozyme analysis revealed that all loci were polymorphic in almost all studied populations. The observed heterozygosity was found to range from 0.146 to 0.258, and Nei's genetic distance between 0.006 and 0.057 among the populations. Bulgarian honey bees are clust...
Genetic and physiology of cold and drought resistance in Turkish red pine (Pinus brutia, Ten.) populations from southern Turkey
Kandemir, Gaye Eren; Kaya, Zeki; Önde, Sertaç; Department of Biology (2002)
The purpose of the study was to determine the pattern of genetic variation in morphological and physiological traits associated with cold and drought stress using seedling from over-exploited and natural populations of Pinus brutia Ten. (Turkish red pine) from southern Turkey. To determine the pattern of genetic variation existing in over-exploited and natural populations, seedlings from 6 populations each with 40 families were raised in Ankara forest nursery from 1998-2000. Three of the populations (Yaylaa...
