木薯新品种(系)在云南的适应性比较研究

以华南205(SC205)为对照品种,研究比较F44、F50、G56等22个木薯品种(系)在云南的适应性。结果表明:单株茎叶鲜重为1.8~11.4 kg,最重的是F81,与F50、哥伦比亚18R、F114等品种系差异极显著;最轻的是GR3,与F44、SC5、新选048等品种(系)差异极显著,与SC205、F50、F114、哥伦比亚18R差异显著;每株鲜薯条数为7.6~17.5条,最多是SC8,比SC205(对照)增加53.5%,而最少的是F108;小区鲜薯重为40.0~100.3 kg,最重为新选048,比SC205(对照)增加70.1%,比鲜薯重最轻的SC5显著高产,与其它品种产量差异不显著,且SC5小区鲜薯重比SC205(对照)减产36.2%。综上所述,综合性状相对适合在云南种植的为SC8、GR3、GR4、新选048、GR024-1、GR024-2、F106、哥伦比亚18R、F114、G37、F44、G30、F100、F539共14个品种(系)。

Comparative Study on the Adaptability of New Cassava Variety in Yunnan

The adaptability of 22 varieties(lines)including F44,F50,G56 was studied.The results showed that the fresh stem and leaf weight was in the range of 1.8～11.4 kg per plant,among which that for F81 was the highest and was extremely higher than that for F50,Columbia 18R,F114 and so on,while that for GR3 was the lowest and was extremely lower than that for F44,SC5,Xinxuan 048.The number of fresh tuberous root was 7.6～17.5 per plant,among which that for SC8 was the highest,53.5% more than it for SC205 and that for F108 was the lowest.The fresh weight of tuberous root was 7.6 ～17.5 per block.Among them that for Xinxuan 048 was the heaviest,70.1% heavier than it for SC205.There was significant difference between Xinxuan 048 and SC5,and the fresh weight of tuberous root of SC5 was 36.2% less than that for SC205 per block.But no significant difference was found between Xinxuan 048 and other varieties(lines).Through the experiment,SC8,GR3,GR4,Xinxuan 048,GR024-1,GR024-2,F106,Columbia 18R,F114,G37,F44,G30,F100,F539 were found more suitable for growing in Yunnan.
