摘　　要：南34是应用籼粳杂交经系统选育成的抗病优质滇型粳稻恢复系。用滇型杂交稻和南34配制的杂交组合杂交优势强、恢复度高、抗病、制种产量高。与滇型三系不育系已配制出系列组合,已通过云南省品种审定委员会审定的组合有滇杂31和滇杂32。Nan 34, bred from multiple crosses of indica-japonica, is a good quality and excellent disease-resistant Dian type restorer line. The hybrid combinations between CMS lines of Dian type and Nan 34 showed strong heterosis, disease-resistant, good seed-set rate, and high-yielding seed production. Among those combinations, Dianza 31 and Dianza 32 were certified and released in Yunnan province in 2002.
