Abstract

A field experiment on detection of rice gall midge biotype under field conditions was carried out in the farm of Agricultural Research Station, Utukur, Kadapa, Y.S.R District during Kharif, 2018, 2019 and 2020 with 17 standard gall midge differentials. Pooled analysis of three years data revealed that, all the entries in Group I exhibited resistance to the biotype of rice gall midge population prevailing in YSR District was following the reaction nearer to the biotype VI with percent similarity index (PSI) of 76.47 per cent

Keywords

Gall midge biotype, Y.S.R District, Andhra Pradesh

Conclusion

The Present research study revealed that the biotype existing in Y.S.R District was following the reaction nearer to the biotype VI with percent similarity index (PSI) of 76.47 per cent and further it has to be confirmed with Molecular identification by using SSR’s primers
