MORPHOLOGICAL CHARACTERIZATION OF LENTIL (LENS CULINARIS MEDIK.) LANDRACES FROM CASTILLA Y LEóN, SPAIN

摘要

Grain size and weight determine crop yield in cereals, whereas in rice grain size and shape is major attribute to identifymarket value and also used for classifying rice genotypes. Rice germplasm collection and knowledge of genetic diversity arerequired for variety improvement. Molecular markers provide powerful tool for identification of genetic variation andmapping of gene/ QTLs. There are a lot of gene/QTLs were identified by different groups on chromosome 3 and 7controlling grain length. Clustering based on grain length divided the 48 accessions into two major clusters with somecontradiction. Genetic relationships among the 48 rice accessions were determined based on allelic diversity using PowerMarker tree, structure analyses and PCA using 51 SSR markers located on chromosome 3 and chromosome 7. TwodimensionalPCA scaling and power marker tree analysis showed high-level of differentiation between Basmati and indicarice accessions and divide these rice accessions in two distinct clusters.
