之豇30豆角系两个早熟品种杂交,经系谱选育而成。其荚型、株型、叶型近于之豇28—2,但其产量是之豇28—2的两倍以上,早熟性也大有改进。 特征特性:植株蔓生,长势偏弱,叶片小,分枝少,以主蔓结角为主。花节位低,基部5节以下的有效果枝数平均为1.75个,而之豇28—2只有0.84个,增加108％,春插至始收50天左右,比之豇28—2提前2—3天,早期产量增加152.6％,总产量增加81％。荚 The cowpea 30 lines of two early maturing hybrids, the genealogy breeding. The pod, plant type, leaf type close to the cowpea 28-2, but its output is more than twice as much as the cowpea 28-2, the precocity is greatly improved. Characteristics: Plant vine, growing weak, small leaves, less branches, mainly the main knot knot. Flower node is low, the base below the 5 effective branches below an average of 1.75, while the 28-2 only 0.84, an increase of 108%, spring inserted into the beginning of 50 days, ahead of the cowpea 28-2 2- Three days, the early yield increased 152.6%, the total output increased 81%. pod
