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

Abstract :

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
