Genotype x environment interactions and stability analysis for seed yield and yield attributing characters in castor (Ricinus communis L.)ttributing characters in castor (Ricinus communis L.)
Abstract
The forty six genotypes including 36 hybrids, 9 parents and GCH-7 as commercial check were evaluated for stability in three environments (sowing dates and spacing) at RRS, AAU, Anand. The partitioning of G x E interaction indicated that substantial portion of G x E interaction was linear for seed yield per plant, number of secondary spikes per plant, number of tertiary spikes per plant, total number of capsules per plant, total length of primary raceme and oil content. Both linear and nonlinear components were equally important for these characters. The study of the stability parameters revealed that parent ANDCP-06-07 as well as hybrids ANDCP-08-01 x JP-65, ANDCP-06-07 x ACP-1-06-07, ANDCP-06-07 x DPC-9, VP-1 x DPC-9 and DPC-9 x ANDCP-06-07-1 had average stability and wider adaptability for seed yield per plant; whereas, parents ACP-1-06-07, SKP-84, ANDCP-06-07-1 and hybrid ACP-1-06-07 x JP-65 had above average stability (bi < 1) and well adapted to poor environment, similarly hybrids ANDCP-08-01 x ANDCP-06-07-1, ACP-06-07-1 x DPC-9, GCH-7 (Check) had below average stability (bi > 1) and specifically adapted to favorable environment. None of the parents or hybrids was found consistently stable for all the characters in any environment.
