The REML/BLUP statistics are analyses that can be used as selective criteria in the routine of maize breeding programs. The present study aims to determine the genetic potential in crosses of landrace populations applying the REML/BLUP methodology, and to identify populations for the synthesis of new populations and intrapopulation selection for family farming systems, as well as genetic consti...

BACKGROUND AND AIMS Although the apical development of wheat has been widely described, studies analysing how genetic breeding over the 20th century influenced the developmental phases and its consequences on yield generation are lacking, especially for durum wheat under field conditions in Mediterranean environments. The aims of this study were to analyse the effects of breeding in Spain and I...

An experiment was conducted to investigate the genetic diversity in the cultivars and F1 hybrids of durum wheat, using agronomic and morphological traits. Evaluation of consistency between choosing parents of crosses based on morphological and agronomic observations and genetic distance obtained from cluster analysis were objectives of this study. Fourty- two genotypes were evaluated using a ra...

Wheat is one of the most widely distributed crops worldwide and is of primary importance as food for human nutrition. Increasing the productivity of the new wheat varieties according to the specific climate of the region is a permanent major task. The impact of environment and some agronomy practices (previous crop and mineral fertilization) on the productivity and the structural elements of yi...

The aim of this study was to determine nature and extent of variability parameters and their utilization in barley breeding programme. A total of 45 F1s along with their parents and F2 populations were evaluated in a randomized block design with 3 replications during Rabi (winter season) 2014. The various traits measured were days to 50% flowering, days to maturity, plant height, flag leaf area...

The present investigation was conducted using 102 wheat genotypes at Research Farm, College of Agriculture, Gwalior during Rabi 2018-2019 in randomized block design with two replications. A set genotype were used to estimate genetic variability, correlation coefficients and path for fourteen yield its accrediting attributes. wide range variation observed important components. GCV PCV recorded h...
