1.5 Biplot analysis
Superior genotypes were easily identified through biplot analysis (Figure 2). The genotype closer to the arrow
mark refers ideal genotype. Genotype G25 was situated in second concentric circle and was also close to arrow
mark indicating most superior genotype followed by G29, G27 and G19. Figure 3 showed mean performance of
selected genotypes.

Note: FW= Fruit weight, FP= Fruits/plant, YP= Yield/plant,
SSc= Selection Score
