Table 5 Selection score of brinjal genotypes based on best selection index
Hajari followed by Kajla, Sada Begun, BARI-9 and
regarded as elite genotypes because of their well
response for yield and other yield enhancing traits.
Selection of parents for high yielding ability in rice
was observed by Purohit and Majumder (2009) based
on best selection score.
Selection score of all genotypes along with the mean
value of best index (I
134
) traits yield/plant (g), no. of
fruits in inflorescence/plant, no. of fruits in
solitary/plant were considered under biplot analysis to
obtain superior genotypes. Genotypes located at the
center of concentric circle and close to the indicator of
superiority (blue arrow line) are Sada Begun followed
by Debjhuri Hajari, Kajla, BARI-9 regarded as
superior genotypes (Figure 2). Thus it can be
concluded that there is an effective reflection of trait
index on genotypic yield and these genotypes would
be effective parent’s in advance profitable breeding
program.
To conclude, simultaneous selection procedure through
Figure 2 Selection of best genotype using biplot analysis.
(NFI.P = No. of fruits in inflorescence/plant, NFS.P = No. of
fruits in solitary/plant, YP = Yield/plant SS = Selection score,
1-14
= Genotype serial of table 5)
different genetic parameters and relationship with direct
effect revealed that yield/plant (g), fresh weight/fruit
(g), no. of fruits in inflorescence/plant, no. of fruits in
S.L.
