Synchronized Selection of White Seeded Finger Millet (Eleusine coracana L.) Genotypes for Yield and Stability

A multi-location field experiment was conducted with 39 white seeded finger millet genotypes including one check which were laid out in Randomized Block Design (RBD) with two replications at research station farms of Vizianagaram, Bangaluru, Hanumanmatti, Mandya, Ranchi and Coimbatore. The study aimed to identify stable white seeded finger millet genotypes across the locations. AMMI analysis and thirteen stability indices based on AMMI were estimated and further non-parametric method of simultaneous selection index was calculated. Large portion of variation was captured by locations (66.7%) followed by GEI and genotypes. Four principal components significantly contributed 94.6% GEI. The AMMI1 biplot identified VR 1000 27.9 q/ha) and GE 4803 (25.7 q/ha) as stable high yielding genotypes. AMMI2 biplot identified GE 4943, GE 4916, GE 2329, GE 5155 and PRM 901 as highly stable genotypes irrespective of yield. Thirteen AMMI based stability indices revealed that PRM 901, GE 2329, PRM 902 and GE 4916 were most stable genotypes. However, synchronized selection for yield and stability revealed VR 1000 as the best white seeded finger millet with both high yield and stable expression over six locations.

Large amount of Environmental variation dominated more compared to interaction and genotypic variation.

GEI was significantly explained by four interaction principal components.

Genotypes; VR 1000 and GE 4803 recorded more than 25 q/ha as well as highly stable as per AMM1 Biplot.

AMM1 based stability parameters identified GE 4943, GE 4916, GE 2329, GE 5155 and PRM 901 as stable among high yielders.

Non parametric indices for synchronized selection revealed, R 1000 as the best white seeded finger millet over multi environments.
