| description | In developing countries, maize genetic improvement materials are often made through
extraction of populations derived from hybrid cultivars that have been released in the
market, involving intra-population improvement in the population. In the third
generation of random mating population from hybrid maize, response selection through
mass selection or ear-to-row selection needs to be compared to determine the
appropriate method of selection in this population. In the third generation of random
mating population, equilibrium has not been reached, resluting in discrepancies of
within family and between family variance. The objective of this work is to compare
response selection of the mass and ear-to-row selection method in a number of
commercial characters of maize and to obtain lines to improve the performance of the
selected population. Twenty four half-sib families (ears) obtained from cross pollination
of second generation of random mating population are planted with one ear one row
pattern in two blocks as replicates. This population was evaluated for six characters:
plant height, ear height, ear length, ear diameter, kernels weight per plant and number of
kernels per plant. The observation data was analysed using analysis of variance to
estimate the heritability by separating the expected mean of squares. The heritability is
used to predict the response selection (R) in every method with selection pressure
(proportion) of 5%. Mass selection by considering the block effect gave the highest R
value for plant height. Mass selection without block effect gave the highest R value for
ear height and ear diameter. Ear-to-row selection based on plot mean gave the highest R
value for ear length and the family mean based of ear-to-row for grain weight per plant
and number of kernels per plant. |
