Selection of pepper parent from a collection of Capsicum annuum landraces based on genetic diversity
Phenotypic divergence among eleven landraces belonging to a collection of Capsicum annuum species and maintained at the Faculty of Science, University of Tunis, was quantiï¬ed by multivariate analysis for seven morphological traits. The multivariate data set was analyzed by canonical discriminant analysis in combination with a clustering procedure using generalized...

Seasonal incidence of Plutella xylostella (Lepidoptera: Plutellidae) and its associated natural enemies in major crucifer growing areas of Kenya
Seasonal incidences of Plutella xylostella, diamondback moth (DBM) and its associated natural enemies were investigated in two agro-ecological zones of the major crucifer growing areas of Kenya in 2005 and 2006. DBM larvae and pupae were collected from the cabbage and kale crops grown in farmers’ field and maintained in the laboratory for the emergence of...

Nature of gene action for yield and yield components in exotic genotypes of Italian millet [Setaria italica (L.) Beauv]
The present investigation was carried out with the objective to find out the extent of genetic variation, heritability and genetic advance for 13 characters in 34 exotic genotypes of Italian millet during Autumn 2008 and Spring 2009. High phenotypic coefficients of variation (PCV) coupled with high genotypic coefficients of variation (GCV) were observed for grain yield per...

Genotype x environment interaction and stability analysis for yield and its components in lentil
The objective of this investigation is to determine the performance and stability of 24 lentil (Lens culinaris Medik.) genotypes under a wide range of variable environments. The regression model and ecovalence (Wi) were used to analyze the response of the lentil genotypes to variable environmental conditions for yield and some of its components in six experiments in three...

Agronomical evaluation of six soybean cultivars using correlation and regression analysis under different irrigation regime conditions
Two field experiments were conducted during summer seasons of 2011 and 2012 to study the effect of irrigation regimes at different growth stages on seed, oil and protein yields of soybean cultivars. The interrelationships among seed yield ha-1 and its attributes through simple correlation and stepwise regression analysis were evaluated. The results indicated that the...
