Multivariate analysis for adaptability and yield stability of rapeseed (Brassica napus L.) strains in different agro-climatic zones
Plant breeders always look for high yielding genotypes based on both genotype and G × E (interaction of genotype with environment) for stability and adaptability in diversified environmental conditions. This present study consists of eight Brassica napus L. strains using RCBD design with th...

Plant breeders always look for high yielding genotypes based on both genotype
and G × E (interaction of genotype with environment) for stability and
adaptability in diversified environmental conditions. This present study
consists of eight Brassica napus L. strains using RCBD design with three
replications and conducted at eight locations in Punjab province, Pakistan
to determine general and specific adaptability in 2014-2015. Additive main
effects and multiplicative interactions (AMMI) study showed that the
environments (86.65%) have more influence to treatment sum of squares as
compare to the interaction of genotype with environment (9.4%) and genotypes
(2.65%) respectively, indicating the presence of adequate genetic variation
for useful selection to identify stable genotypes. G x E interaction was
further partitioned by principal component analysis (PCA). The first four
multiplicative axis terms (IPCA1, IPCA2, IPCA3 and IPCA4) give detailed
54.0%, 28.0%, 9.9% and 5.6% of GEI sum of squares (SS), respectively. The
AMMI method was used to recognize suitable genotype / genotypes to specific
locations / environments. The results showed that genotypes RBN-08004,
RBN-04021 and 11-CBN 006 were more stable with the lowest interaction and
have general adaptability with yield near about their mean yield. Genotype
RBN-08004 has more than average yield, IPCA value closer to zero (1.8),
genotype selection index (GSI) is 4 and least AMMI stability value (ASV) of
3.6 therefore considered the most stable. According to AMMI analysis,
KN-253, KN-256 and RBN-08004 (adaptive group 1) exhibited specific
adaptability for Bhakar and Khanpur with yield greater than mean and
positive interaction. Genotype RBN-04047 (adaptive group 2) which has yield
lesser than mean yield and positive interaction showed specific adaptability
for Chakwal and Karore. It was observed that stability evaluation through
AMMI analysis may be used for selection of genotypes from experiments
performed under different environmental conditions. |
