Abstract
Twelve Pinus taeda were used as mother trees and one P. rigida plus tree was used as pollen tree for 12 cross combinations. Nine P. densiflora plus trees(4 mother and 7 pollen trees) were used as parents for 11 cross combinations. Those parents and 10 progenies were analyzed for LAP of ${\times}$P. taeda rigida hybrid and P. densiflora and for peroxidase of ${\times}$P. taeda rigida. The analysis, based on the banding patterns, indicate three alleles for LAP-A locus(A1, A2, A3) and two alleles for LAP-B locus (B1, B2) in ${\times}$P. taeda rigida hybrids. Chi-square test on the segregation for progenies did not show significant differences. The results indicated good agreement with monohybrid Mendelian inheritance. Independence test for occurrence frequency of 2 alleles(LAP-A3, LAP-B2) illustrated that there is neither linkage nor repulsion relationship between LAP-A3 and LAP-B2 alleles. Three band at LAP-A locus were always exhibited from all parents and their progenies of P. densiflora. However, the occurrence of two bands at LAP-B locus was variable, one bands assumed as homozygous alleles(B2/B2) and two bands as heterozygous alleles(B1/B2). The segregation ratio for progenies of P. densiflora suggested that LAP-B locus may be controlled by two alleles(B1 and B2). Three Peroxidase loci(Px-A, Px-B, Px-C) assumed to be controlled by allozyme in ${\times}$P. taeda rigida hybrid. The Px-B and Px-C loci could not find out the variations from banding patterns of parents and their progenies, while the Px-A locus showed the variations of occurrence frequency by two bands. The segregation ratio for A1/A2 at LAP-A locus suggest that the peroxidase allozymes of ${\times}$P. taeda rigida hybrid appeare to be monomeric products; that is, Px-A locus may be controlled by two alleles (A1 and A2).
테다${\times}$리기다 잡종차대(雜種次代)에 대(對)해 LAP와 Peroxidase의 유전양식(遺傳樣式)을 분석(分析)하였으며 소나무 수형목간(秀型木間) 11개(個) 인공교배조합(人工交配組合)에 의(依)해 조성(造成)된 차대(次代)의 LAP동위효소(同位酵素)의 유전양식(遺傳樣式)에 대(對)해 분석(分析)하였다. 테다${\times}$리기다 잡종(雜種)에서 2개(個)의 유전자좌(遺傳子座)(LAP-A, LAP-B)를 추정(推定), 이들은 각각(各各)(A1, A2, A3)와 (B1, B2)의 대립유전자(對立遺傳子)에 의(依)해 지배(支配)받고 있으며 소나무에서도 LAP-A, LAP-B 두개의 유전자좌(遺傳子座)를 추정(推定)하여 모수간(母樹間)에 변이(變異)가 있는 LAP-B는 B1과 B2의 2개 대립유전자(對立遺傳子)에 의(依)해 지배(支配)받고 있음을 밝혀냈다. 테다${\times}$리기다 잡종(雜種)의 Peroxidase에 대(對)해서는 3가지 유전자좌(遺傳子座)(Px-A, Px-B, Px-C)를 추정(推定)하여 모수간(母樹間) 변이(變異)를 나타낸 Px-A 유전자좌(遺傳子座)는 A1과 A2의 두개 대립유전자(對立遺傳子)에 의(依)하여 지배(支配)받고 있음을 밝혀냈다. 이상(以上)의 LAP와 Peroxidase동위효소(同位酵素)는 단량체(單量體)로써 단순(單純)한 멘델유전(遺傳)을 하는 것으로 나타났다.
