Development of rice varieties resistant to yellow stem borer (YSB) is very crucial. Agrobacterium-mediated transformation of CrvlB gene under wound inducible gene promoter mpi (maize proteinase inhibitor) into a local rice variety Rojolele had been conducted. PCR analysis proved that Cry1 B gene had been integrated into plant genome of 3R25 and 3R5 rice lines. Segregation analysis using PCR for…
