Inheritance studies of grain shape and aroma traits of rice genotypes in Uganda rice germplasm

A study was conducted to determine the mode of inheritance for grain shape and aroma traits of lines in the Uganda rice germplasm. Five aromatic and four non-aromatic rice lines were crossed in screen house using North Carolina Design II at the National Crops Resources Research Institute, Uganda. The resulting F2 seeds and their parents were planted in the field using complete randomized block design in two...

Agromorphological characterization of scarlet eggplant (Solanum aethiopicum L.) grown in the Republic of Benin

The scarlet eggplant (Solanum aethiopicum L.) is an African traditional vegetable grown for its edibles leaves and fruits, which can contribute to food security in Republic of Benin. However, very little information is available on the genetic variability of this vegetable for varietal improvement purposes. Sixty accessions of scarlet eggplants collected throughout 52 villages in Benin republic were characterized using...

Response of selected sorghum (sorghum bicolor (l.) moench) genotypes to striga hermonthica (del.) benth in western Kenya

Sorghum is an important staple food crop in Kenya, but its yield is low due to many constraints which include diseases, drought, soil fertility, and pests, notably parasitic weed Striga hermonthica. Twenty elite sorghum genotypes and one resistant check were evaluated in three replications in a complete randomized design in Agar Gel (AG) experiment and randomized complete block design on selected Striga hotspot farms at...

Water use efficiency: Behavior of upland rice lines under water deficit

Upland rice (Oryza sativa) is affected by several biotic and abiotic factors that limit the yield potential of cultivars. In relation to water deficiency, the development of drought tolerant and water efficient cultivars is a priority in breeding programs. With this study aimed to evaluate the agronomic behavior of upland rice lines subjected to different irrigations depths aiming for the selection of genotypes that are...

Inheritance and detection of QTL in cowpea resistance to brown blotch disease

Brown blotch disease caused by Colletotrichum capsici, is one of the most important disease affecting cowpea production in Burkna Faso. Every year the disease can cause yield losses as high as 42 to 100% on farmer’s fileds. This study aimed to understand the inheritance of its resistance in cowpea and also identify quantitative trait loci (QTL) associated with the resistance. Seedlings of parents and F1, F2 and...

Exploiting combining ability in a diallel cross between native and elite cucumber (Cucumis sativus L.) varieties

F1 progenies derived from a set of diallel crosses involving native and 5 elite cucumber varieties were evaluated in a randomized complete block design (RCBD) with three replications to study combining ability for some important agronomic traits. The analysis of variance revealed that the mean squares due to genotypes were significant for the traits studied, indicating wide diversity among the parents. Mean squares for...

BLUP & AMMI model for stability analysis of wheat genotypes evaluated under irrigated timely sown trials in North Eastern Plains Zone of India

Environments explained 49.4%, G×E interaction 28.1%, and genotypes only 5.6% of the total sum of squares due to treatments for the first year of studied period 2018-2019 and 2019-2020. More than 95% of variations had been accounted for by the first seven interaction principal components. Superiority indexes had identified WH1239, DBW187, HD3249 genotypes as per the BLUE estimates.  Same genotypes were...

Impact of climate change on armyworm infestation on maize in Nigeria: A review

Maize (Zea mays) is an important food crop in Nigeria, and it is fast becoming the most widely cultivated crop. Several efforts have been made by the Nigeria Government to make the country self-sufficiency in maize production, but some biotic and abiotic factors are impeding this achievement. Among the biotic constraints militating against maize production in Nigeria, armyworm (Spodoptera frugiperda) is most devastating...
