寒露干冷风是影响我省晚造产量不高不稳的主要因素之一.即使目前某些抗寒力较强的品种,抽穗扬花时若碰上“寒露风”也难免受其为害.因此,选育从根本上避过“寒露风”的威胁,而又利于提早冬种的早熟高产稳产新品种,是水稻新品种选育工作当务之急.“桂 Cold and dry dew is one of the main factors affecting the late yielding instability in our province.Even at present some of the more cold hardiness varieties, heading flowering if run into ”cold dew wind“ is also inevitably affected by its damage. Therefore, the breeding of radically avoid the ”cold dew wind “ threat, but also conducive to early winter varieties of early maturity high yield stable new varieties of rice breeding work is imperative. ”
