Descrizione Genetic Dissection of Grain Weight & Related Traits in Bread Wheat
In this manuscript, we have used for the first time two important approaches of genetic dissection (QTL interval mapping and association mapping) together for the study of marker-trait associations for the identification of molecular markers associated with a variety of economically important traits with emphasis on grain weight (GW)in bread wheat. We mainly focused on the following aspects: (i) Preparation of whole-genome framework linkage map of an intervarietal RIL mapping population developed specifically for GW and derived from the cross Chinese Spring × Rye Selection 111 . (ii) Single-locus QTL analysis (interval mapping) for GW (including other grain traits), and other agronomically important traits using the above RIL mapping population. (iii) Study of QTL × QTL epistatic interactions and QTL × environment interactions using two-locus QTL analysis. (iv) Study of genetic diversity and population structure of a collection of elite Indian bread wheat cultivars. (v) Association mapping of GW and other agronomically important traits using above collection of elite Indian bread wheat cultivars.
