Abstract
Fourteen genotypes of Brassica (Brassica comprestries L.) were studied in the Laboratory under different salinity levels (EC=5,
10,15,20,25 d.Sm-1
) for preliminary evaluation in respect of germination percentage and relative growth rate. Five genotypes among
14 were selected for yield evaluation in Multilocational trials at five different natural saline areas of Punjab province. Seed
germination ranged form 20-40% at EC=25d.Sm-1 Raya Anmol exhibited highest relative growth rate and lowest relative growth rate
was exhibited by No. ZBJ. 97003. The stability analysis of seed yield of Brassica genotypes collected from different Multilocational
trials indicated that high yielding genotypes Khanpur Raya (880 Kgha-1
) showed its suitability for rich environment due to having
regression coefficient significantly different from one. However, the second high yielding genotype RL-18 (729 Kgha-1
) which had
non significant regression coefficient value and non significant value of standard deviation to regression showed more stability and
hence it may be grown safely with more economic benefits on saline soils.
