the present invention provides ‘ 01pm0212 ’ as a new , distinct and stable variety of loblolly pine that is a product of a planned breeding program conducted by the inventor ( s ) in 2000 in ravenel , s . c . the objective of the planned breeding program was to develop a new loblolly pine tree with vigorous growth ; high biomass production for timber , fiber or fuel use ; straight stem ; and high resistance to fusiform rust infection that would achieve commercial maturity sooner than typical loblolly pine trees in the southeast coastal zone of the united states . for purposes of this application , the term “ variety ” is equivalent to clone , as ‘ 01pm0212 ’ may be reproduced asexually and all resulting individuals are essentially identical genetically . for the purposes of this application , during “ mass control pollination ” ( mcp ) a large number of female strobili are pollinated and produce seedlings ( or rooted cuttings ) for use in regeneration . the large scale of mcp distinguishes this process from traditional “ controlled pollination ” ( cp ), which is used to produce seed for progeny tests in order to evaluate the genetic value of the parents . bramlett , d . l ., “ genetic gain from mass controlled pollination and topworking ”, journal of forestry , vol . 95 ( 1997 ) pp . 15 - 19 . another difference between mcp and cp is the amount of control that is used to reduce contamination . cp flowers are isolated from any outside pollen contamination and pollen is collected and processed to be nearly 100 % free of contaminating pollen . in cp , the goal is that every seed has a known mother and father . the mcp process allows some contamination , so faster and less expensive techniques are used to produce large quantities of seed with the majority of seed having a known mother and a known father . the following traits have been repeatedly observed and are determined to be unique characteristics of ‘ 01pm0212 ’ which in combination distinguish this loblolly pine tree as a new and distinct loblolly pine variety : in comparison to the full - sibling family of which it is a member , ‘ 01pm0212 ’ differs primarily in the traits listed in table 1 . of the many commercial varieties known to the present inventor ( s ), the most similar in comparison to the new loblolly pine ‘ 01pm0212 ’ is pinus aa - 32 ( unpatented ), in the following characteristics described in table 2 : the examples described herein are illustrative of the present invention and are not intended to be limitations thereon . different embodiments of the present invention have been described according to the present invention . many modifications and variations may be made to the methods and plants described and illustrated herein without departing from the spirit and scope of the invention . the new pinus variety is a product of a controlled breeding program conducted by the inventor ( s ), in ravenel , s . c . the objective of the breeding program was to develop a new loblolly pine tree with vigorous growth , straight stem and high resistance to fusiform rust infection that would achieve commercial maturity sooner than typical trees in the southeast coastal zone . the new pinus variety originated from a cross made by the inventor ( s ) in 2000 in ravenel , s . c . the new pinus variety is a progeny of a first - generation selection pollinated by a second - generation selection . the female or seed parent is the unpatented pinus taeda variety ag - 373 selected in williamsburg county , south carolina , and is a first - generation selection . the male or pollen parent is the unpatented pinus taeda variety designated ag - 76 selected in a progeny test in georgetown county , south carolina , and is a second - generation selection . cross pollination occurred in 2000 followed by induction of somatic embryogenesis tissue and cryopreservation of embryogenic tissue in 2001 in summerville , s . c . the first somatic seedlings of the new pinus variety were produced in 2002 . rooted cuttings were produced from the somatic seedling hedges and then planted in 2004 in 3 field experiments located in berkeley county , south carolina . among these 3 field experiments , a total of 16 ramets of the new pinus variety were planted ranging from about 4 - 8 ramets per field experiment . the new pinus variety was discovered and selected by the inventors within the progeny of the stated cross in 2005 . the new pinus variety was selected by the inventors based on its superior growth , stem straightness , and low rates of forking and stem sinuosity . asexual reproduction of the new pinus variety by somatic embryogenesis , a tissue culture technique for embryo multiplication , was first performed in august , 2001 , in summerville , s . c ., and the propagated variety has demonstrated that the combination of characteristics as herein disclosed for the new variety are firmly fixed and retained through successive generations of asexual reproduction . the new variety reproduces true to type . the new pinus ‘ 01pm0212 ’ has not been observed under all possible environmental conditions . the phenotype of the new loblolly pine tree variety may vary with environmental variations such as temperature , light intensity and day length , as well as , growing conditions variations such as irrigation , fertilization , pruning , and pest control , without any change in the genotype of the new loblolly pine tree variety . the aforementioned photographs , together with the following observations , measurements and values describe loblolly pine trees of ‘ 01pm0212 ’ as grown in the pine farm in berkeley county , south carolina , under conditions which closely approximate those generally used in commercial practice . unless otherwise stated , the detailed botanical description includes observations , measurements and values based on 4 - year old ‘ 01pm0212 ’ trees grown in the pine farm in berkeley county , south carolina , from autumn of 2004 to summer of 2008 . quantified measurements are expressed as an average of measurements taken from a number of trees of ‘ 01pm0212 ’. the measurements of any individual tree , or any group of trees , of the new variety may vary from the stated average . color references are made to the mcc munsell color charts for plant tissues ( mcc ), 1968 edition , except where general colors of ordinary significance are used . color values were taken under daylight conditions at approximately 11 a . m . in summerville , s . c . all of the trees of ‘ 01pm0212 ’, insofar as they have been observed , have been identical in all the characteristics described below . female or seed parent : pinus taeda variety designated ‘ ag -

0493 and ript - 1040 were from the same linkage , although they were still almost completely independent with a genetic map distance of 41 cm . the 5 ′ ends of all forward primers were modified with the universal m13 sequence cacgacgttgtaaaacgac ( seq id no : 1 ), and the reverse primers all had the sequence gtttctt at the 5 ′ end . these were used with a fluorescently labeled m13 primer of the same sequence as the 5 ′ modification of the forward primers . data was generated for one negative reagent control , the 12 ctab extracted template dna &# 39 ; s , and three ctab extracted dna &# 39 ; s of previously genotyped reference control samples of loblolly pine ; b - 145 - l , 487ncs (= 7 - 56 ), and 8 - 1070 ). the following reagents and concentrations were used in a 6 μl volume pcr reaction to amplify products : 20 ng template dna , 5 × colorless gotag ™ r × n buffer with 15 mm mgcl 2 dilute to 1 . 0 ×, promega dntps at 66 μm each base , 0 . 04 μm forward primer , 0 . 16 reverse primer , 0 . 16 μm fluorescently labeled m13 primer ( dye label based on product pool in table ), and 1 unit hot start taq polymerase . thermocycling was conducted in 96 - well format using ptc - 200 thermocyclers with heated bonnets from mj - research using the following parameters : 94 ° c . for 2 minutes , followed by 20 cycles of 94 ° c . for 30 seconds , 65 ° c . minus 0 . 5 ° c . per cycle for 30 seconds , 72 ° c . for 1 minute , then 25 cycles of 92 ° c . for 30 seconds , 55 ° c . for 30 seconds , and 72 ° c . for 1 minute thirty seconds followed by a final extension at 72 ° c . for 15 minutes . the products were then held at 4 ° c . until analyzed . pcr products were combined and diluted in 18 mega - ohm water into 4 product pools ( tables 3a and 3b ) such that one template and several markers could be analyzed in the same capillary . two microliters of each product pool were then loaded on an abi 3130 genetic analyzer using the default run module for a 36 cm capillary array modified by the addition of 5 minutes to the run time . an abi liz600 internal size standard was used in each well at a concentration of 10 μl size standard / ml abi hidi formamide . product fragments were then analyzed with genemapper ™ 3 . 7 analysis software using microsatellite default settings as the analysis method . binning and naming of alleles were done using a scheme which allows for freedom of marker dye modification among projects to meet specific needs while still maintaining the same allele names for unifying data sets among projects . allele names were first assigned to pcr products from each marker run with a 15 - tree reference panel . markers from these initial reference runs were labeled in one of four dye - labels , vic , 6 - fam , ned , or pet . the allele names for a marker were based on fragment size as it appeared for whatever dye used in the reference sample runs . any novel allele fragments in a subsequent project are named based on their relative base pair sizing within this reference frame , and subsequently become part of an additive set of named allele bins for that marker . the largest bin set for a marker is then used for all consecutive projects . dye migration sizing differences among project runs are corrected when needed ( i . e . marker a was run with 6 - fam in project 1 , but vic in project 2 ) for by shifting the positions of all bins in a set to the left (−) or right (+) based on dye migration difference values collected previously . any further refinements needed due to slight run - to - run variation can also be judged by the binning of the reference controls and should be applied to all bins in a set equally . the three positive control reference samples included in pcr and sizing in this project matched previous allele calls . sas and perl procs were used to process the data and genalex v . 6 . 1 to calculate a genetic distance ( methods = codom - genotypic ) matrix . all 13 markers gave excellent results for the 12 loblolly variety samples , plus our three control samples . allelic peaks were easily binned and called using our existing marker panels and bin sets . of the possible 13 * 12 = 156 data points ( i . e ., co - dominant genotypes ), 155 were scored (& lt ; 0 . 7 % missing data ). all 12 variety samples provided distinct allelic profiles , with one pair of varieties ( pt6615 and pt7207 ) showing high allele similarity . the sample genotypes for all 13 markers and 12 varieties plus 3 control trees are provided in tables 4a - 4c . one missing data point is contained in the table for ‘ 01pm0212 ’ and is denoted by a 0 at each allele . ‘ 01pm0212 ’ can be distinguished from other pine genotypes using the primer : ptrip — 1077 . tables 4a -
