Adoptability of high yielding three line rice (Oryza sativa L.) hybrids

Abstract

A study on adoptability of rice hybrids was carried out through analysing the data on grain yield and other important traits according to Eberhart and Russell Model. For this, multi locational trial was carried out with 33 hybrids at three locations viz., Hyderabad, Maruteru and Bargarh. Eight characters were studied and all the characters including grain yield were showing significant difference in their phenotypic expression across environments except number of panicles and panicle length which were less influenced. Based on the linear component (bi), non-linear response (s2di) and high mean performance (X), six hybridsviz. RP6AxRP58R, RP6AxRP49R, RP6AxRP5R, RP2AxRP2R, RP6AxRP60R and RP11AxRP16R were found to be stable across nvironments.
