Expression of indica rice resistant sources to Brown planthopper（BPH） in indica-japonica hybrids and their utillzation

摘要

We studied the genetic mode in transferring BPH-resistance genes from indica varieties to japonica varieties January 1988 to December 1989 in Nanjing, Jiangsu Province. Indica varieties selected on a basis of BPH-resistance genes, i.e., Yankeng 2 (japonica), 02428 (japonica), 40316 (indica-japonica progeny),
