Stability of 18 bottle gourd (Lagenaria siceraria (Mol.) Standl.) varieties was studied for fruit yield and yield
contributing traits during Rabi-summer seasons of 2011-12, 2012-13 and 2013-14. Pooled analysis of variance
revealed highly signifi cant differences among the varieties for all the traits except for leaf width, ovary length
and fruit weight suggesting enough genetic variability among the genotypes for all these traits. Similarly the
mean squares for environments were also signifi cant for all the traits except peduncle length and fruit length
indicting that the environments under study are diverse enough. Further, genotype × environment (G × E)
interactions were also signifi cant for all the traits suggesting that the traits responded to the environments
differently. The environments (linear) also differed signifi cantly for all the traits except leaf width and peduncle
length which indicates that the environments selected for testing of genotypes were quite varied in their effect
on the performance of genotypes. Considering all the stability parameters, the varieties, Narendra Rashmi and
IIHR-19-1 proved to be most stable genotypes exhibiting signifi cantly higher mean fruit yield/ha. For the yield
contributing traits viz., fruit number, Narendra Dharidhar, KBGR-12, Pusa Samrudhi and Kalyanpur Long were
stable over environments and for fruit weight Kashi Ganga, Punjab Komal and Pant Lauki-3 were stable with
highest mean values, unit regression and least deviation which can be exploited for these yield contributing traits
in the bottle gourd improvement programs.
