我省水稻地方高秆品种植株甚高。株型大多披散,不耐肥,极易倒伏,是提高产量的限制因素。但地方品种具有适应性强、长势旺、比较耐粗和穗大、粒多等优点,因而在育种上应当积极加以利用,作为选育地区适应性良好的新品种之亲本材料。国际水稻所育成的第一个突破性半矮生性品种“IR_3”,也是以高秆种“彼泰”与我国台湾省的 My province rice places tall stalk varieties plant is very high. Plant type mostly loose, not fattening, easy to lodging, is to increase the yield constraints. However, the local cultivars have the advantages of strong adaptability, growing vigor, relatively rough and spike, more grain and so on. Therefore, they should be actively used in breeding as the parent material of new varieties with good adaptability in breeding areas. The first breakthrough semi-dwarf breed “IR_3” bred by the International Rice Plant is also based on the high-stalk type “Petai” and the Taiwan Province
