摘要
水稻材料A20的三柱头性状是施爱农于1990年夏发现的。由于多柱头状可能是寻找无融合生殖的标志,而无融合生殖具有固定杂种优势的潜力和改良作物育种方法的能力,因此有必要从细胞学、遗传学、胚胎学等方面对水稻三柱头材料A20进行研究。本文就A20三柱头性状的表达和遗传作一报道。
The three stigmas in rice line A20 were discovered in 1990. The percentage of the three stig- mas of A20 was 12.8%±10.4% and affected by environmental factors. The three stigmas were heritable and controlled by major recessive genes. They also could be transfered to other rice materials by hybridization.
