Hung F.K., Wei S.M., Liang G.W., Huang S.S., Luo S.Y. and Li Q., 2011, Studies on core collection of rice germplasms which resistant to different rice brown planthopper biotypes and rice gall midge China type IV, Journal of Mosquito Research, 1(3): 1-5 (doi: 10.5376/jmr.2011.01.0003)

In the present paper, core collection of rice germplasms which are resistant to different biotypes of rice brown planthopper (BPH) and rice gall midge (GM) were generally evaluated by means of the grey correlative degree. The results indicated that correlative degree of IR29692-99-3-2-1, IR36, RP1579-1862-72-31-52, DUO KANG No.1 with standard variety (Yuexiangzhan) was the biggest value among core collection which was resistant to BPH biotype II, moderately resistant to biotype II, resistant to biotype Bangladesh, resistant to rice gall midge China type IV respectively. Four varieties can be selected firstly in the breeding of resistance to the BPH and GM.
