Diamondback moth (DBM), Plutella xylostella L. is the most injurious defoliage insect pest of canola in Ardabil province of Iran. It occurs annually and causes damage in canola fields. This study was performed to identify QTLs controlling resistance to diamondback moth using SSR and RAPD markers. An F2:4 population of 180 families derived from crossing between cv. ‘SLMO46’ and cv. ‘Quantum’ wer...

the construction of molecular maps and identification of genomic regions controlling quantitative traits have great significance for plant breeders. in this study, a genetic analysis of quantitative trait loci (qtls) affecting the heading date of rice was performed using an f2 population of a cross between two iranian landrace cultivars, domsephid and gerdeh, comprising 192 plants. an approxima...

A meta-QTL analysis was conducted in Indian mustard to identify robust and stable meta-QTLs (MQTLs) by utilizing 1504 available QTLs, which included 891 QTLs for yield-related traits 613 quality traits. For traits, a total of 57 MQTLs (YRTs_MQTLs) were uncovered from the clustering 560 projected had 4.18-fold smaller confidence interval (CI) than that initial whereas, as many 51 (Quality_MQTLs)...

Revealing QTLs with a minor effect in complex traits remains difficult. Initial strategies had limited success because of interference by major QTLs and epistasis. New strategies focused on eliminating major QTLs in subsequent mapping experiments. Since genetic analysis of superior segregants from natural diploid strains usually also reveals QTLs linked to the inferior parent, we have extended ...

Industrial production of the edible basidiomycete Pleurotus ostreatus (oyster mushroom) is based on a solid fermentation process in which a limited number of selected strains are used. Optimization of industrial mushroom production depends on improving the culture process and breeding new strains with higher yields and productivities. Traditionally, fungal breeding has been carried out by an em...

To clarify the genetic mechanisms of stroke susceptibility in the stroke-prone spontaneously hypertensive rat (SHRSP), a quantitative trait locus (QTL) analysis was performed. Using 295 F2 rats of a cross between SHRSP/Izm and SHR/Izm, 2 major QTLs for stroke latency under salt loading were identified on chromosomes (chr) 1 and 18. Evaluation of 6 reciprocal single and double congenic rats for ...

mapping the QTLs of agronomic and physiological traits, 149 double haploid (DH) lines from a cross between an Australian cultivar, Clipper (salt susceptible), and an Algerian landrace, Sahara3771 (salt tolerant), were evaluated under natural saline (Yazd Station, ECsoil=10-12.8 ds/m and ECwater= 9-10 ds/m) and normal (Karaj Station, ECsoil and ECwater ~2-2.5 ds/m) environments. There were remar...
