About 80% kharif area of maize cultivation in India is under
rainfed condit ion where uncertainty of rainfall is a
ubiquitous phenomenon which limiting its productivity.
Primary and secondary stress responsive traits are
mainly on quantitat ive loci, which make the direct
selection of traits difficult. The present experiment aimed
to identify the maize hybrids suitable for dual purpose
under low moisture stress condition, identification of
secondary traits associated with fodder and grain yield
and calculation of correlation which could be useful for
effective selection for fodder and grain yield. Using 37
maize genotypes, evaluated under 3 moisture regimes
for green fodder and grain yield. Association analysis
was done among the secondary traits and yield. Among
the genotypes significant variability was showed for all
characters. The hybrids BAUIM-2 x HKI-1532 and BAUIM-
3 x HKI-1532 found suitable for dual purpose exhibited
maximum GFY/P under irrigated, rainfed and stress (-
50kPa) conditions while, hybrid BAUIM-5 x HKI-1532 found
suitable for fodder yield. Hybrids BAUIM-4 x HKI-335 and
BQPM-4 x HKI-1532 suitable for stress conditions. The
traits stomatal frequency, stay green, tassel blast and
green fodder yield per plant showed normal probability
distribution; whereas, relative leaf water content, anthesis
silk interval, leaf area index, leaf senescence, leaf firing,
plant bareness, leaf rolling and grain yield per plant non-
normal distribution. Bartlett test for homogeneity of
variance was non-significant for LA-3 and LA-cob. The
correlation coefficient indicated that, traits GY/P with SG
(0.46); TB (-0.39); LR (-0.40); LAI (0.57), BP (-0.57). GFY/
P with SG (0.48); TB (-0.39); LR (-0.41), BP (0.48) showed
significant association among each other’s.
