Genetic and Environmental Analysis of Vegetative and Yield Traits in the Oil Palm ( Elaeis Sp.).
(Obafemi Awolowo University, 1986)A total of 21 hybrids of oil palm consisting of four Elaeis,guineensis palms selected for shortness, three F1 interspecific hybrids (Elaeis oleifera x E. guineensis), 13 hybrids from the first backcross gene-ration (BC1) ... -
Genetic Variability and Predicted Responses to Four Types of Progeny Selection in a Nigeria Maize (Zeamays L.) population.
(Obafemi Awolowo University, 1986)Genetic variability and predicted responses to full-sib (FS), half-sib (HS), Si and S1 testcross (TCH) selection methods were studied in the open-pollinating maize variety, TZSR-Y-1. Evaluation of progress after one cycle ... -
Genotype X Environment Component of Variance and its Implications in Maize (Zeamays L.) Yield Trials.
(Obafemi Awolowo University, 1985)Grain yield data obtained from yield trials conducted in 1981 and 1982 for five open-pollinating cultivars and eight varietal hybrids of maize (Zea mays L.) were used to investigate the effectiveness of 3 different yield ... -
Germination of Euphorbia Heterophylla L. and its Control in Cowpea (Vigna Unguiculata (L) walp).
(Obafemi Awolowo University, 1986)In order to understand the influence of temperature and light duration on the germination of Euphorbia heterophylla L., freshly harvested and pre-chilled seeds of the weed were incubated in an illuminated cooled incubator ... -
Growth and Yield of Cassava (Manihot Esculenta Crantz), Cowpea ( Vigna Unguiculata s.sp Unguiculata (L) Walp) and Maize (Zeamays L.) in Sole Cropping and Intercropping.
(Obafemi Awolowo University, 1986)Growth and yield of cowpea (Vigna unquiculata s.sp. unguiculata (L) Walp) maize (Zea mays L.) and cassava (Manihot._esculenta Crantz) were studied at two plant populations in sole crop and in a three crop association during ... -
Heterotic Patterns of Early Maturing Inbred Lines of Maize (Zea mays L.) in Striga–Infested And Striga–Free Environments
(2015-03-27)The study was designed to separate early maturing yellow- and white-endosperm inbred lines of maize (Zea mays L.) into heterotic groups; evaluate the effects of tester, location and infestation of Striga hermonthica (Del.) ... -
Inheritance of Resistance to Cowpea Aphid-Borne Mosaic Virus and Southern Bean Mosaic Virus in Cowpea. Vigna Unguiculata S. SP. Unguiculata (L) Walp.
(Obafemi Awolowo University, 1986)Abstract: The mode of inheritance of resistance to cowpea aphid-borne mosaic virus (CAMV) and southern bean mosaic virus (SBMV) was determined in the following cowpea (Vigna unguiculata s.sp. unguiculata (L) Walp) varieties: ... -
Inheritance of Yield and Agronomic Traits in a Maize (Zeamays L.) Population at Two Levels of Inbreeding.
(Obafemi Awolowo University, 1986)Hybrids resulting from diallel crosses of ten radom lines at the second (S2) and fifth (S5) generations of inbreeding in the TZSR-W population of maize (Zea mays L.) were studied. Eight of the lines were common to both ... -
Seed Setting under Controlled Natural Cross Pollination in Three Populations of Coconut (Cocas Nucifera L.)
(2015-04-20)The purpose of this study was for high rate production of coconut natural hybrids resulting from controlled natural pollination. The primary objective of this study was to evaluate the seed setting percentage resulting ... -
Studies on Cowpea Varietal Resistance to the Cowpea Flower and Pod Borer, Maruca Testulalis (Geyer) (Lepidoptera Pyralidae).
(Obafemi Awolowo University, 1985)Several varieties of cowpea, Vigna unguiculata s.sp. unguiculata (L,) Walp., were screened for resistance to the cowpea flower and pod borer, Maruca testulalis (Geyer) using free-choice field trials, cohort tests in large ... -
A Taxonomic Study of the Acridoidea (Orthoptera) of Southwestern Nigeria.
(Obafemi Awolowo University, 1987)The Acridoidea of southwestern Nigeria was studied. Collection of species of Acridoidea was made from different parts of southwestern Nigeria between 1982 and 1986. The collected specimens were identified and a checklist ...
