优异种质的选育主要的稻种资源用来培育具理想性状的品种。他们在农艺性状、谷粒品质、抗病性、抗虫性、蛋白质含量、耐旱性、耐有害土壤、耐深水和淹水以及耐低温或高温等方面进行了研究,以寻求对种质的改良。其中,有些方面已取得重要进展,有的则收效不大。现将主要结果简述于下: 农艺性状国际水稻研究所的GEU计划非常重视提高产量潜力(最为重要的一个农艺性
Breeding for excellent germplasm The main rice germplasm is used to breed varieties with ideal traits. They conducted research on agronomic traits, grain quality, disease resistance, insect resistance, protein content, drought tolerance, resistance to noxious soils, resistance to deep and submerged water, as well as resistance to low or high temperatures, in search of germplasm Improved. Some of them have made important progress, while others have not achieved much success. The main results are summarized below: Agronomic traits The GEI program at the International Rice Research Institute places great emphasis on increasing yield potential (the most important agronomic
