分析了 1996～ 1998年我国杂交水稻生产应用中主要品种的胞质类型及播种情况。现阶段 ,中国杂交水稻种植面积占水稻年播种面积的 5 0 %以上。生产上应用的三系杂交稻仍以野败胞质为主 ,其次为冈· D型和印尼水田谷型 ,后者的面积比重在逐年增加。两系杂交稻研究取得新突破 ,10余个组合通过了省级审定 ,培矮 6 4S的广泛应用展示了两系杂交稻超三系杂交稻的诱人前景。我国业已育成超级杂交稻苗头组合 ,个别组合在部分百亩 (6 .6 7hm2 )连片示范点已经达到了日产稻谷10 0 kg/ hm2的超级稻指标
The types of cytoplasm and seeding of the main cultivars in hybrid rice production in China from 1996 to 1998 were analyzed. At this stage, the area under hybrid rice cultivation in China accounts for more than 50% of the sown area of rice. The three-line hybrid rice used in production still dominated by wild lutein, followed by Gang-D type and paddy-valley type in Indonesia, whose area proportion increased year by year. Two-line hybrid rice research made new breakthroughs, more than 10 combinations passed the provincial-level validation, Pei-dai 6 4S widely demonstrated the attractive prospects of two-line hybrid rice Tri-line hybrid rice. China has bred super hybrid rice seedlings combinations, individual combinations in the part of the mu (6.66hm2) contiguous demonstration sites have reached the daily output of rice 100kg / hm2 super rice indicators
