Book Description
Over the last few years, Agricultural lands have dramatically decreased in the world. Mainly the over populated countries are seriously affected by this problem. To ensure food security for the ever increasing population we have to grow more food in limited area. For this reason the demand of diversified high yielding varieties is upgrading day by day. Genetic divergence is important for genetic improvement. This book provides attractive ideas about highest diversified varieties of the most widely adopted crop all over the world i.e wheat. The performance of twenty five wheat genotypes based on thirteen agronomic characters and molecular marker analyzed here from which the readers know about the most important characters for improving grain yield in wheat. The result of interaction within genotypes and environment should help people to be interested about heritable characters of wheat. From this research the author highly recommended three varieties for farmers to reinforce both the grain quality and quantity. This book might become a valuable source of information to the researcher and other personnel who are working for the betterment of agriculture.

Book Description
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 x 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 x QTL epistatic interactions and QTL x 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."

Book Description
The present investigation was undertaken with the objective to evaluate the nature and magnitude of genetic variability and correlation of different spike traits and other character association with grain yield. Eighteen diverse bread wheat (Triticum aestivum L.em Thell.) genotypes and 72 F1 lines were evaluated to estimate the extent of association with respect to spike traits and grain yield. The coefficient for genotypic correlation for most of the character combination was higher in magnitude, as compared to corresponding phenotypic correlation coefficient, indicating largely the strong inherent nature of traits recorded in the present investigation. The yield per plant exhibited positive and strong association with all the traits except with 100 grain weight. From the present investigation, it could be suggested that breeder has to work cautiously for any breeding program aimed at improving particularly the 100 grain weight.
