記者6月15日從廣西林科院獲悉，經過多年努力，廣西建成全國最大馬尾松無性系種質基因庫，收集無性系1778個，累計生產種子近2萬公斤，4個國家級和5個自治區級馬尾松良種基地全部實現種苗一體化工程，推廣造林14.80萬公頃，產生直接經濟效益10.45億元、間接經濟效益62.68億元。
作為松樹的代表樹種，馬尾松在我國分布極廣，北自河南山東，南至廣西廣東，東自沿海省市，西至四川貴州，覆蓋長江、黃河、珠江流域，遍布中國人口密集區，是南方主要用材樹種，也是荒山造林的先鋒樹種。馬尾松用途廣泛，為建筑、枕木、礦柱、制板、家具、包裝箱及木纖維加工的重要原料。馬尾松樹干可割取松脂，根部樹脂含量豐富，樹干及根部可培養茯苓、蕈類，樹皮可提取栲膠，經濟價值相當高。
