Rice varieties/lines and BPH insects
Indica rice lines RBPH16 and RBPH327 are introgressed lines, derived from ruffipogon , which showed high levels of resistance against BPH insects (Li et al . 2019; Yang et al . 2020).Indica rice varieties ARC5984 and PTB33 have also been found to be highly resistant to BPH (Lin et al ., 2020; Cheng et al ., 2021). Indica line 9311 and Japonica rice varieties NIP, ZH11, and BaiMao were highly susceptible to BPH. BPH insects were collected from rice fields in Nanning of Guangxi Province, China, and were reared on 9311 in growth chambers at 27±2 °C, 75±5% relative humidity, and a light/dark photoperiod of 14:10 h.
