用新育成大穗型恢复系金恢 2 10 1与野败不育系配组 12个杂交稻组合 ,在稀植 (2 3cm× 2 6cm ,每 6 6 7m2 插植 1 1万丛 )条件下比较产量试验。结果金恢 2 10 1系列杂交稻普遍表现大穗、重穗等特点 ,其中博优 2 10 1等 7个组合比汕优 6 3显著增产 ,可进一步扩大试验示范。
A total of 12 hybrid rice combinations with the newly-bred restorer line Jinhui 2 10 1 and wild-bred male sterile line were compared under thin planting (23 cm × 26 cm, 1 106 000 colonies per 6 6 7 m 2) Yield test. Results Jinhui 2 10 1 hybrid rice showed the characters of large panicle and heavy panicle. Seven combinations such as Boyou 2 10 1 increased significantly compared with Shanyou 6 3, which could further expand the experimental demonstration.
