e1“The results showed high and moderate heritability estimates of 94.0 and 40.0 for striga emergence count and striga syndrome rating respectively, while low heritability estimates of 13.0, 11.32, 16.0, 5.70 and 16.22% were obtained for tolerance index, days to tasseling, days silking, kernel rows/cob and grain yield respectively.”

Other claims from this paper (13)
- Observation Heritability estimate for striga emergence count was 94.0%.
- Observation Heritability estimate for striga syndrome rating was 40.0%.
- Observation Heritability estimate for tolerance index was 13.0%.
- Observation Heritability estimate for days to tasseling was 11.32%.
- Observation Heritability estimate for days silking was 16.0%.
- Observation Heritability estimate for kernel rows per cob was 5.70%.
- Association Genotypic correlations of striga emergence count with maize agronomic traits were positive and significant.
- Association Phenotypic correlations of striga count with other maize agronomic traits were positive and significant.
- Association Striga count was negatively correlated with striga syndrome rating.
- Observation Maize ear aspect alone contributed 19.4% to grain yield.
- Observation Inherent yield loss of 23.0% was estimated if striga is left uncontrolled.
- Association Most striga and maize agronomic traits were positively associated with grain yield under striga infestation, except plant and ear heights.
- Recommendation Genotypic and phenotypic correlations and heritability estimates are suitable models for selecting S. lutea tolerant maize genotypes.
