Genetic variability of morphological and yield traits in Dolichos bean (Lablab purpureus L.)

Thirty genotypes of Dolichos bean (Lablab purpureus) were evaluated to study the genetic variability on yield, yield-contributing and related characters. The highest and lowest coefficient of variation was observed for single podded clusters per plant and protein content respectively. Little or no difference between the phenotypic and genotypic coefficients of variability in the expression of various horticultural...

Allelopathic effect of aqueous leaves extract of Moringa oleifera L. on seedling growth of Cicer arietinum L.

Allelopathy is an interference mechanism, in which live or dead plant materials release chemical substances, which inhibit or stimulate the associated plant growth. In the present study an attempt has been made to investigate the potential allelopathic effects at different concentrations (2.5, 5.0, 7.5 and 10.0%) of Moringa oleifera leaves extract on seed germination, seed biomass, radicle length and...

Additive main effects and multiplicative interactions model (AMMI) and genotype main effect and genotype by environment interaction (GGE) biplot analysis of multi-environmental wheat variety trials

Genotype by environment (G×E) interaction is associated with the differential performance of genotypes tested at different locations and in different years, and influences selection and recommendation of cultivars. Wheat genotypes were evaluated in six environments to determine the G×E interactions and stability of the genotypes. Additive main effects and multiplicative interactions (AMMI) was conducted for...

Genetic and phenotypic diversity in selected genotypes of tef [Eragrostis tef (Zucc.)] Trotter

Tef [Eragrostis tef (Zucc.) Trotter] is an important staple food crop, especially in Ethiopia where it is annually grown on 2.8 million hectares of land. It is important for food security in the region, in spite of having a low yield, mainly due to lodging. In this study, 15 representative landraces as well as three improved varieties have been selected for in-depth characterization of many parameters, especially...

Responses of sapodilla fruit (Manilkara zapota [L.] P. Royen) to postharvest treatment with 1methylcyclopropene

The effect of 1-methylcyclopropene (1-MCP) on ripening and chilling injury in sapodilla fruits was investigated. Sapodilla fruits were treated with four different concentrations of 1-MCP (0.0, 0.2, 0.5 or 1.0 µL/L) and two exposure times (12 or 24 h) in sealed chambers under different temperatures (15 and 25°C). Following the previous treatment, fruits were stored at 25°C with 85 to 95%...

Responses of Mmupudu (Mimusops zeyheri) indigenous fruit tree to three soil types

Mmupudu (Mimusops zeyheri) is an indigenous fruit tree to South Africa, with the potential of being domesticated for its aesthetic and nutritional attributes in rural and urban communities which were historically settled on heavy clay and loam soils, respectively. A pot study was conducted to investigate the performance of M. zeyheri seedlings under loam, clay and sandy soils. Relative to loam, clay increased...

Effect of calcium fortification and steaming on chemical, physical and cooking properties of milled rice

Milled rice of two varieties, Jehlum and Shlimar Rice-1 were subjected to seven chemical treatments and five steaming treatments for calcium fortification. Physic-chemical and organoleptic evaluations of each treatment were carried out before and after fortification. Jehlum proved superior in whiteness (L -value), starch and sugar content, volume expansion, elongation ratio and minimum cooking time, while Shalimar...
