摘要
在雨水偏少的安徽淮北地区 ,旱播旱管栽培条件下 ,对本课题组选育的 4个耐旱水稻新品系进行了丰产性和耐旱性的品比试验。结果表明 ,4个耐旱水稻新品系 2PB0 1、2PB0 2、2PB0 3和 2PB0 4分别比对照巴西陆稻耐旱且增产 6.2 %、2 4.6%、18.5 %及2 3 .6%。除 2PB0 1外 ,其余 3个品系均比对照巴西陆稻增产显著。
The test was held in the Huaibei region with little rain, Anhui province. The upland rice varieties with the gene cluster-DNA of Alternanthera philoxeroides Griseb(popular name-Geming wild) were comparatively experimented in high yield property and drought endurance. The result showed that four drought-enduring rice varieties:2PB01, 2PB02, 2PB03 and 2PB04 not only increased production by 6.2%, 24.6%, 18.5%, 23.6% respectively over Brazilian Upland Rice but also were with the characters of drought endurance. Other three varieties but 2PB01 had remarkably yield-increasing,compared with Brazilian Upland Rice.
