Deciphering higher order non-allelic interactions for quantitative characters through twelve generation mean analysis in castor (Ricinus communis L.)

The genetic architecture of oil content, seed yield and its related biometric traits in castor was investigated through generation mean analysis four crosses viz., JP 104 × JI 433, SKP 84 437 441 twelve generations (P1, P2, F1, F2, B1, B2, B11, B12, B21, B22, B1s B2s). Significance simple scaling tests Cavali’s joint test all the for one or more indicated presence digenic trigenic gene interactions. Further, significant χ2(2) value at six degrees freedom based on six- parameter model Hill (1966), depicted higher order epistasis characters. ten-parameter found to be adequate cross 433 effective length primary raceme; number capsules branches per plant. On other hand, χ2(3) with two remaining showing and/or linkage. All ten-parameters were shelling out turn percentage three days maturity raceme 433. Moreover, duplicate reported inheritance component traits. This information can utilized developing lines high content.
