黄麻引进新品系的比较试验研究

为了筛选出在黄麻纤维成熟期干麻皮产量较高及种子成熟期单株种子产量较高的黄麻新品系，从福建农林大学引进14个黄麻新品系进行比较试验研究，在纤维成熟和种子成熟期分别考查农艺性状、经济性状及产量等多项指标。结果表明，在纤维成熟期，干麻皮产量4183.66~5197.62 kg/hm2之间，最高的为编号J8的品系，达到 5197.62 kg/hm2 ，位于第1位，另编号为J7的品系，产量为5150.93 kg/hm2，位居第2位，且主要经济性状优良；种子成熟期单株种子产量在2.7~11.9 g之间，最高的为编号J7品系，单株种子产量为11.9 g，排在首位，排名第2的为J10，单株种子产量为11.4 g。

Comparative Experiment on Newly Introduced Jute (Corchorus L.) Lines

The current experiment was conducted to screen out novel jute lines with high seed yield per plant at seed mature stage and high fiber yield at fiber mature stage. 14 new jute lines introduced from Fujian Agriculture and Forestry University were used in the comparative experiment to investigate agronomic traits, economic traits, yield and other indicators at seed and fiber mature stage, respectively. The results showed that at fiber mature stage fiber yield was 4183.66-5197.62 kg/ hm2. J8 line had the highest fiber yield (5197.62 kg/hm2) followed by J7 (5150.93 kg/hm2), which displayed superb economic traits. At seed mature stage, seed yield per plant was 2.7-11.9g. J7 line produced most seed (11.9g) and J10 had the second highest yield (11.4g).
