Genetic Divergence in Lentil

چکیده

Fifty genotypes of lentil (Lens culnaris Medik) were evaluated under eight environments for seed yield and its associated traits. All the genotypes were grouped into seven clusters. The composition of various clusters varied from 2 to 12. Clustering pattern revealed the distribution of the genotypes belonging to the same origin in more than one cluster indicating non-parallism between geographic and genetic diversity. Members of cluster II and VII were highly diverse from each other as these clusters showed maximum inter-cluster distance. The entries of cluster VII showed the highest mean values for number of primary branches-1, biological yield plant-1, seed yield plant-1 and 100-seed weight. The promising genotypes for seed yield, 100-seed weight, pods plant-1, seeds pod1 and early maturity were identified from cluster II and VII on the basis of mean values which could be utilized for hybridization programme for the development of high yielding genotypes.

Assessment on induced genetic variability and divergence in the mutagenized lentil populations of microsperma and macrosperma cultivars developed using physical and chemical mutagenesis

Induced mutagenesis was employed to create genetic variation in the lentil cultivars for yield improvement. The assessments were made on genetic variability, character association, and genetic divergence among the twelve mutagenized populations and one parent population of each of the two lentil cultivars, developed by single and combination treatments with gamma rays and hydrazine hydrates. An...

Leveraging genomic resources of model species for the assessment of diversity and phylogeny in wild and domesticated lentil.

Advances in comparative genomics have provided significant opportunities for analysis of genetic diversity in species with limited genomic resources, such as the genus Lens. Medicago truncatula expressed sequence tags (ESTs) were aligned with the Arabidopsis thaliana genome sequence to identify conserved exon sequences and splice sites in the ESTs. Conserved primers (CPs) based on M. truncatula...

Evaluation and characterization of ICARDAelite germplasm of lentil

Food legumes are a central part of the diet for many communities around the world and lentil could be an excellent choice to provide more nutritious foods. Lentil breeding program aims to develop adapted, high yielding, biotic and abiotic tolerant varieties. The success of any breeding program is dependent on the availability of genetic materials with sufficient diversity. In order to investiga...

An analysis of genetic variation and divergence in Indian tropical polyvoltine silkworm (Bombyx mori L.) genotypes

The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. The D2 (Mahalonobis? distance) statistics reveal...

Construction of a Chickpea Linkage Map and Its Comparison With Maps of Pea and Lentil

Journal of Heredity 199738:115-119; 0022-1503/97/J5.00 An integrated genetic linkage map of chickpea (Clcei) has been developed that consists of 9 morphological, 27 isozyme, 10 RFLP, and 45 RAPD markers covering 550 cM. The map was made from segregation data from populations of three interspecific crosses of cultivated chickpea (C. arietlnum, 2n = 16) and a closely related wild species (C. retl...

Identification and Functional Prediction of Long Non-Coding RNAs Responsive to Drought stress in Lens culinaris L.

Drought stress is one of the main environmental factors that affects growth and productivity of crop plants, including lentil. In the course of evolution evolution, crucial genetic regulations mediated by non-coding RNAs (ncRNAs) have emerged in plant in response to drought and other abiotic stresses. In the present study, after identifying lncRNAs within the expression profile of lentil, RNA-s...
