Soybean is an important source of plant protein used in human diets. Cadmium (Cd) from agricultural soil a toxic metal for plants, including soybean. Furthermore, the cadmium taken up to seeds soybean and becomes risk animals by feed food chain. A method avoid this represented selection breeding lines/cultivars with genetic potential minimized accumulation. This work reports approach assisted D...
Improved crop varieties are needed to sustain the food supply, to fi ght climate changes, water scarcity, temperature increase and a high variability of rainfalls. Variability of drought and increase in soil salinity have negative effects on plant growth and abiotic stresses seriously threaten sustainable agricultural production. To overcome the infl uence of abiotic stresses, new tolerant plan...
Performance of any breeding program is mainly due to the correlation among yield and relative importance of each component. This study was conducted to analysis the correlation among grain yield and some important traits in seventhin spring canola (Brassica napus L.) cultivars at the farm in safiabad, from 2014 to 2015. A randomized complete blocks design with four replications was used. The an...
in this study, 100 moghani sheep from breeding station located in jaafarabad, moghan were genotyped for exon 1 of igf-i gene, using pcr-sscp. different band patterns were obtained in this site gene that was studied. based on sscp patterns, three genotypes bc, bd and bb obtained with frequencies of 65%, 26% and 9%, respectively. the genotype frequencies had a significant deviation from hwe. in a...
In the context of genomic selection, we evaluated and compared breeding programs using either index selection or independent culling for recurrent parents. We simulated a clonally propagated crop program 20 cycles an economic with two unfavourably correlated traits under selection. Cycle time from crossing to parents was kept same both strategies. Both methods led increasingly unfavourable gene...
thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...
Breeding program aimed at converting standard maize inbred lines to their quality protein maize (QPM) counterparts for growing in temperate climate is being conducted at Maize Research Institute (MRI). The objective of the research presented herein was to develop QPM versions of two commercial ZP inbreds through marker assisted selection (MAS) with opaque2 specific molecular markers, while main...
Gene pyramiding is an effective strategy to provide a durable and high level of powdery mildew (PM) resistance in mungbean [Vigna radiata (L.) R. Wilczek]. The objectives this study were evaluate PM levels pyramided BC2F1 progenies derived from marker-assisted selection KING (recurrent parent) × SUPER5 (donor cross measure their agronomic performance under fi eld condition. results showed that ...
Since the introduction of genomic selection in plant breeding, high genetic gains have been realized different breeding programs. Various methods based on estimated values (GEBVs) for selecting parental lines that maximize gain as well improving predictive performance proposed. Unfortunately, it remains difficult to measure what extent these really long-term values. In this study, we propose or...
