水稻新品种比较试验

Comparison Experiments on New Rice Varieties

采用大区对比法对14个水稻品种进行了比较试验,分别对各品种的生育期、分蘖动态和成穗率、主要经济性状、产量等指标进行了考察。结果表明:珍珠糯、银籼2024、青两优香916、特两优香916、Ⅱ优330、籼糯98-01、豫两优688和Ⅱ优1511等8个水稻新品种表现为生育期短,成穗率较高,经济性状突出,产量较高,建议通过品种审定后,在该地区进行大面积的推广种植。

A comparison experiment of 14 rice varieties was carried out by wide field trial. The performances of new varieties such as growing periods, tillering behavior and percentage of ear-bearing tiller, main economical characters and yields were studied. The results indicated that eight new varieties named pearl glutinous, silver hsien 2024, qingliangyouxiang 916, teliangyouxiang 916, two Superior 330 and two Superior 1511 had shorter growing periods, higher percentage of ear-bearing tiller, better economical characters and higher yield. So these varieties may be planted widely once they passed the variety certification.
