80年代以来,收集和引进野生橡胶树种质资源3000多个,包括橡胶树属7个种或变种。经初步研究,预测产量优于推广品系RRIM600的19个,占参测种质的8％。侧脉孔管优于RRIM600120％以上的25个,占参测种质的21,7％,来自阿克里的种质不论预测产量或乳管较优的新种质,其入选率均最高。抗寒力优于93—114、GT1等北部推广品系的有9个,占参测种质的9.5％。测量173个新种质中,生势优良的占55.5％。以郎多尼亚州的生势较优的入选率最高,达60％以上。同时也发现一些种质具有一定的抗病或抗风能力。同功酶酯酶谱带分析亦有初步结果。初步研究结果表明亚马孙新种质资源蕴藏着高产、抗逆性强、生势旺盛等特异性状,确是威克姆系统种质不可比拟的。
Since the 1980s, more than 3,000 wild rubber tree germplasm resources have been collected and introduced, including 7 species or varieties of Hevea. After a preliminary study, the predicted yield was better than 19 strains of the extended line RRIM600, accounting for 8% of the reference germplasm. The lateral velar tube was superior to RRIM6001 20%, accounting for 21.7% of the total germplasm collected. The germplasm from Acre had the highest selection rate regardless of the predicted yield or the new germplasm with better ducts. Cold hardiness was better than 93-114, and there were 9 northern popularization lines such as GT1, accounting for 9.5% of the germplasm tested. Of the 173 new germplasm tested, 55.5% were excellent. The highest prevalence in the Bordeaux region is over 60%. Also found that some germplasm has a certain resistance or wind resistance. The same enzyme esterase band analysis also has preliminary results. Preliminary results show that the new germplasm resources in Amazon contain high yield, strong resistance, strong potential and other specific traits, indeed Wickham system germplasm incomparable.
