摘　　要：热研7—33—97是一个速生高产抗性较强的橡胶树优良品种。两院试验场高级试验区头9个割年的鉴定结果,其平均干胶产量为4.35千克/株·年、1910千克/公顷·年,分别为对照RRIM600的131.8％和169.5％,干胶含量高,产胶潜力大,干胶性能好,抗风、抗寒能力都优于RRIM600,1993年被评为中规模推广级品种。SCATC 7-33-97 is an improved clone of rapid growth, high yield and better resistance. An advanced test trial on SCATC 7-33-97 over the first nine years of tapping showed that the mean yield of dry rubber was 4. 35 kg/year/tree or 1910 kg/hm2/year, which was 131.8% or 169. 5% that of the control clone RRIM600, The dry rubber content of SCATC 7-33-97 was higher than that of the control.The potential of rubber yield and quality of dry rubber were promising, This clone acquired a much better wind firmness and cold hardiness than RRIM600,and hence was recommended for moderate scale release in 1993.
