Inheritance and linkage of genetic markers and resistance to Ascochyta blight in lentil by Bouazza Sakr Download PDF EPUB FB2

Inheritance of foliar resistance to ascochyta blight in lentil (Lens culinaris) was studied using four resistant (ILLILL‘Indianhead’, and ‘Laird') and two susceptible inbreds. Distribution of Ascochyta blight in North Dakota and eastern Montana lentil production fields in Solid circle = field assessed, disease present; open circle = field assessed, disease absent.

A field was only considered positive for Ascochyta blight if the causal pathogen was isolated from symptomatic lentil tissues collected in that field. Abstract Foliar resistance to Ascochyta lentis is controlled at a single major locus by a dominant gene (AbR 1) in the lentil accession ILL (cv ‘Northfield’).Flanking RAPD markers that are closely linked to the resistance locus in coupling phase were identified by bulked segregant by:   Rodda et al.

Name of population. Summary. The mode of inheritance of resistance to Ascochyta blight (Ascochyta rabiei) isolate G in chickpea was studied in three cross combinations and their was found that resistance variety I was controlled by a single dominant gene by: lentil. Breeding for host resistance has been suggested as an efficient means to control this disease.

Physiological and Molecular Plant Pathology Lentil (Lens culinaris Medik.) is a diploid (2n = 2x = 14), self-pollinating, cool-season, grain legume that is cultivated worldwide and is highly valuable due to its high protein content.

However, lentil production is constrained by many factors including biotic stresses, majority of which are fungal diseases such as ascochyta blight (AB), fusarium wilt, rust, stemphylium blight, anthracnose Cited by: 7.

Ascochyta blight (AB) caused by Ascochyta rabiei (Pass.) Labr. is an important and widespread disease of chickpea (Cicer arietinum L.) worldwide. The disease is particularly severe under cool and humid weather conditions. Breeding for host resistance is an efficient means to combat this disease.

In this paper, attempts have been made to summarize the progress made in identifying resistance. Ascochyta blight of lentil is a prevalent disease in many lentil producing regions and can cause major yield and grain quality losses.

The most environmentally acceptable and economically profitable method of control is to develop varieties with high levels of durable resistance.

However, no MAS systems have yet been established [14].

The first genetic mapping (linkage analysis) began in lentils in (Ladizinsky, ), and the first map comprising DNA-based markers was produced by Havey and Muehlbauer ().Subsequent maps were published by several researchers ().With the development of PCR-based markers, the number of mapped markers across the Lens genome increased dramatically (Kumar et al.,Kumar et al., Cited by: 1.
