This experiment was conducted at Debre Zeit and Akaki during 2004-2005 cropping season on F2-derived F4 bulk families of three crosses, viz, DZ-01-974 x DZ-01-2786, DZ-01-974 x DZ-Cr-37 and Alba x Kaye Murri. To estimate the correlations and path coefficients between yield and yield components, 63 F4 families were taken randomly from each of the three crosses. The 189 F4 families, five parents ...

crop production in arid and semi arid environments has been affected by drought stress. forage production have important role on animal production in this area. in order to determine the effect of irrigation intervals on the yield and morphological characteristics of forage millet, sorghum and corn, an experiment was conducted in a split plot with a randomized complete block design with four re...

in order to evaluate the effect of sowing date and plant density on the morphological triats, yield and yield components of sweet corn (zea mays l. var sc. 403) an experiment was conducted at the khorasan razavi agricultural research and natural resources center, mashhad, iran during 2008. this experiment was carried out as split plot based on rcbd with four replications. the sowing date (14th ...

Thirty advanced breeding lines of deep-water rice were evaluated during T. Aman season (rainfed ecosystem) with a view to finding out variability and genetic association for grain yield and its component characters. All the tested characters showed significant variation. The highest genetic variability was obtained in filled grains/panicle followed by plant height. Panicles/plant, filled grains...

Genotypic variation is useful to breeders when selecting genotypes to improve particular traits. Inorder to study of genetic diversity 20 genotypes of Hordeum murynum studied in the form of randomized complete block design the experimental field of islamic azad university shahre rey branch with 3 replication in the year 2012. Notes traits was conducted including days to heading, days t...

Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

For crop production it is desirable for the mapping between genotype and phenotype to be consistent, such that an optimized genotype produces uniform sets of individual plants. Uniformity is strongly selected in breeding programs, usually automatically, as harvest equipment eliminates severely non-uniform individuals. Uniformity is genetically controlled, is known to be increased by interplant ...
