    摘要:

    对2004~2006年吉林省参加预试或完成区试新品系的丰产性、稻米品质、抗稻瘟病性等进行了分析。结果表明:①参试新品系丰产性突出的比例很低,产量超过对照8%的品系数不到5%,产量超过对照5%的比例虽有所增加,但也只有15%左右;②米质特别优良的比例太低,品质达一等米标准的只占参试品系的1%,达二等米标准的也不到10%;③参试品系的抗稻瘟病性较好,预试中穗瘟抗性达到中抗(MR)的比例达35%以上,但在完成区试品系中比例有所下降。本文还对育种中存在上述问题的原因及解决途径进行了讨论。

    Abstract:

    Productivity,quality and resistance to rice blast of strains which were tested in 2004 to 2006 in Jilin province were analyzed.The results showed that percentage of superior productive strains was less.Yield of 5% of tested strains increased by 8% comparing with the control and 15% of tested strains increased by 5%.Grain quality was very low also.Only 1% of tested strains reached the first class and less than 10% of that reached the second class.The resistance to rice blast was pretty well among tested strains.35% of tested strains reached medium resistant,but the percentage of resistant decreased in strains which has been regional trial planted.Reasons which caused these problems and solution were discussed in the paper.
