“…e short picking interval encouraged the plant to produce higher number of fruits per plant and long picking interval increased the fruit size and weight [27]. e present result is in agreement with two reports from Ethiopia [21,22,28]. A similar result had also been reported from India [29,30].…”

No research has been done to assess the genetic diversity of Okra (Abelmoschus esculentus) genotypes in Ethiopia based on the combination of agromorphology and biochemical traits of the crop. Such an assessment would assist in the development of high fruit yield and nutritionally good cultivars. Therefore, 36 okra genotypes were evaluated for 29 agromorphological and biochemical traits at the Melkassa Agricultural Research Center (Ethiopia) during the 2018 main rainy season, using a 6 × 6 simple lattice design. Analysis of variance showed significant differences among genotypes for all the studied traits, except number of flower epicalyxes and fruit diameter. Genotypic coefficients of variation and phenotypic coefficient of variation were high for number of branches, internode length, fresh fruit weight, number of mature pods, fruit yield per plant, fruit yield per hectare, seed yield per plant, seed yield per hectare, and seed protein content. Heritability values ranged between 33.63 and 99.81%, while the genetic advance as percentage of mean ranged between 4.29 and 95.45%. High broad sense heritability was coupled with high GAM for plant height, branch, internod length, fruit length, panicle length, fresh fruit weight, number of fruits per plant, number of mature pods, seed yield per plant, seed yield per hectare, and fibre and protein content. In conclusion, this study showed the presence of genetic variation among genotypes for fruit yield, seed yield, and nutritional content, indicating the potential success of developing okra varieties for high fruit yielding and good nutritional content.

“…This is in tandem with studies by Temam et al . [ 35 ] who reported differences in stem girths of various okra cultivars ranging from 14.5–30.5 cm in Ethiopia. These results contradict the findings of Azeem et al ., [ 36 ] who reported an insignificant difference in stem girth among the various okra cultivars under his study.…”

Seed production system and adaptability of okra (Abelmoschus esculentus L.) cultivars in Buea, Cameroon

et al. 2022

Okra is grown globally for its nutritional and economic benefits. Okra seeds ensure continuous production of the crop but challenges of poor production, adaptability and management may not allow the seeds to express their full potential. There are two seed production systems in Cameroon; the informal and formal. In Buea, the informal seed system is used by most farmers for seed production/utilization and farmers are reluctant to use hybrid seeds. This study aimed to assess the informal seed system of okra and evaluate the adaptability of seed produce from informal and formal systems in Buea. A survey and a field experiment were carried out. The designs for the survey and field experiment were stratified random sampling and randomized complete block design respectively. Data collection for the survey was done using questionnaires and other data collection instruments, while for the field experiment, data was collected on germination, vegetative growth parameters, incidence and severity of pests / diseases and yield. Data analysis for the survey was done using descriptive statistics, while data from the field experiment was done using a two-way ANOVA test and treatment means compared using the Tukey test at 5% probability. Results from the survey showed that women (60%) were mostly involved in seed production by mass selection from two landraces identified. Preservation of seeds was mostly done with the use of wood ash (58%) and insects were the major postharvest pest (76%). For the field experiment, at 66 DAP, Yellen recorded the highest significant number of leaves (13.417), leaf area (771.4 cm2) and the number of branches (5.64). Clemson spineless recorded the highest significant incidence (89.9%) and severity for pests / diseases while Kirikou and Landrace recorded the least incidence (0.0%) and severity. Kirikou recorded the highest significant yield (6.0 tons/ha), followed by Landrace (5.3 tons/ha). These findings reveal the performance of the landrace and provide reasons why farmers in Buea are reluctant to use hybrid okra seeds. The Landrace should certainly have adaptable genes, coupled with the autogamous nature of okra which encourages inbreeding for homozygous traits, which are dominant in expression compared to heterozygous traits.

“…Heritability determines the degree of phenotypic variation caused by additive gene activity. Heritability is a valuable indication of how well traits are handed down from parents to their offspring (Temam et al, 2020). The proportion of heritable variation impacts the consistency of progeny performance in following genera-tions.…”

“…Table 3 and Fig programmes of sesame development for characteristics such as seed length and seed yield per plant will be implemented in the future. Backcrossing is essential to concentrate these traits in genotypes since many traits seem to be governed by alleles with additive effects (Temam et al, 2020). For seed thickness to No.…”

Sesame (Sesamum indicum L.) was renowned in the ancient ages for the stability of its healthy oil, accessibility of extraction, and drought resilience. Consequently, to produce novel varieties, the present work entails the utilization of basic metrics of variability and genetic variation. The investigation included 60 sesame genotypes and 13 quantitative characteristics. The analysis of variance revealed that genotypes were significant for all of the parameters assessed (P>0.05 and P>0.01). The average seed yield per plant was 6.93g, ranging from 4.84 to 9.17g. In all of the traits studied, the phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variance (GCV). The tense relationship between PCV and GCV values indicated that the environment had minimal impact on the expression of the traits under investigation. The no. of branches, no. of capsules/axil, capsules per plant, no. of seeds per capsule, and oil content suggested higher estimations of PCV and GCV. The heritability varied from 75.13% for seed width to 99.03% for no. of capsules/axil. The genetic advance (GA) percent means varied from 7.71 (seed length) to 110.93 (no. of capsules/axil) at 5% selection intensity. plant height, no. of branches, 1000 seed weight, capsule length, capsules per plant, no. of seeds per capsule, seed thickness, oil content, and seed yield per plant all showed substantial heredity and a high GA% mean. Because of this, the traits of additive genetic control and direct selection in sesame have a high potential for increasing its yield.
