通过对生育期、株高、分枝数、主茎节数、单株荚数、百粒重等性状的相关分析和灰色关联度分析，结果表明，分枝数、单株荚数是影响产量的关键因素。
Comparative analysis and grey correlation degree were carried on soybean traits, the results were as follows: branch number and pods per plant have more important effect on yields.
茎超过20厘米高的，在果期80厘米，单一或分枝在中部以上。
Stems more than 20 cm tall, to 80 cm at fruiting, simple or branched above middle.
水分处理对生长高峰期株高和分枝长度的相对生长率没有显著作用，高施肥量则加大了其相对生长率。
Higher fertilization promoted the relative height and length growth rates of the branches, but watering treatments hadn't significant effects on them.
缅甸种质具平均成熟期长、茎秆粗、主茎分枝数多、百粒重轻等特点。
The accessions from Burma, had longest growth period, widest diameter of stem, more plant branch and smallest 100-seed weight.
结果表明，以垄栽覆盖地膜方式马铃薯的出苗率最高，成熟期最早，植株最高，分枝数最多；但茎粗、叶面积指数、匍匐茎长、产量和单株生物学产量则以浅旋耕覆盖稻草方式最高；
The results showed that, for all treatment, the seedling emergence rate and the stem length of ridge cultivation model was the highest and its mature date was the earliest.
