摘要
对选自全国的23个马尾松(PinusmassonianaLamb.)种源,在七个测试点进行了生长性状的稳定性评定和试点效应分析。结果表明:测试点间和种源间均存在着显著差异,在结合种源稳定性分析中,参试的23个种源,可划分成四个类型:高产稳定型,只有P_6一个种源;高产非稳定型,包括八个种源;低产稳定型,包括十二个种源;低产不稳定型,包括P_1和P_22两个种源。又由于种源与地点交互作用达到极显著,所以同一种源在不同试验点表现也有明显差异,通过适宜性分析确定了各种源最适宜种植的场点。七个试点对种源判别能力分析表明,以L_5、L_6具有较强的判别优良基因型的能力。
Test location effects and stability in stem volume at 7 test locations were analysed for 23provenances of Masson pine (Pinus messoniana Lamb.) from China.The results show that significantdifferences existed both among test locations and the provenances.According to their stem volumesand genetic stability,the 23 provenances could be divided into 4 types: the type with high and stableproductivity, including 1 provenance(P_6);the type with high and unstable productivity,including 8provenances;the type with low and stable productivity,including 12 provenances; the type with lowand unstable such as P_(22)and P_1 provenances. Because the interaction of provenances x location was significant,same provenances at different test locations showed great difference.The suitable analysiswas made on respective suitable location for 23 provenances.The provenances decision abitity analysisin 7 locations shows that L_5, L_6 possessed a superior genetype ability.
