Book Description
Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.

Book Description
Drought is a major constraint limiting dry bean (Phaseolus vulgaris L.) yield worldwide. Some lines express tolerance but the mechanisms are not well understood. We sought to: i) identify quantitative trait loci (QTL) conditioning drought tolerance in a bi-parental mapping population, ii) use selective phenotyping to characterize important phenotypic traits associated with drought tolerance, and iii) perform association mapping to discover novel QTL conditioning drought tolerance. We tested 140 RILs (Buster/Roza) for yield under multiple stress (MS) and terminal drought (DS). A genetic linkage map (953 cM) was generated using SNP markers. Two major QTL influencing seed yield (SY) were observed. The SY1.1 QTL explained up to 37% ( R2) of the phenotypic variance for seed yield under MS and was consistently expressed each year. The SY2.1 QTL was detected under DS (33%) and MS (23%). For extensive phenotyping, 40 lines from the original mapping population were evaluated for 19 traits. The phenotypic extremes helped to sort through traits relevant to stress response in the population and verified the effect of two major QTL for yield response under terminal drought. Of all traits examined, pod wall ratio (PW), biomass (BM) and greenness (NDVI) were most associated with SY under stress followed by phenology. Phenotypic extremes validated QTL discovered with whole RIL population and identified new QTL for PW1.2BR and NDVI 1.1BR on chromosome Pv01. A panel of 160 lines and cultivars from Durango race was tested under MS and DS for one year and genotyped with 5398 SNPs. The PW, BM, and phenology traits were all correlated with SY under DS. Association mapping revealed novel QTL for days to flowering (DF), plant height (PH), seed weight (SW), BM, PW, and SY under MS and DF, BM, SW, and geometric mean under DS. This study offers QTL influencing yield under multiple stress environments and identification of traits associated with drought tolerance.

Book Description
Climate change is expected to have a drastic impact on agronomic conditions including temperature, precipitation, soil nutrients, and the incidence of disease pests, to name a few. To face this looming threat, significant progress in developing new breeding strategies has been made over the last few decades. The second volume of Genomics and Breeding for Climate-Resilient Crops describes various genomic and breeding approaches for the genetic improvement of the major target traits. Topics covered include: flowering time; root traits; cold, heat and drought tolerance; water use efficiency; flooding and submergence tolerance; disease and insect resistance; nutrient use efficiency; nitrogen fixation; carbon sequestration; and greenhouse gas emissions.

Book Description
This book provides insights into the genetics and the latest advances in genomics research on the common bean, offering a timely overview of topics that are pertinent for future developments in legume genomics. The common bean (Phaseolus vulgaris L.) is the most important grain legume crop for food consumption worldwide, as well as a model for legume research, and the availability of the genome sequence has completely changed the paradigm of the ongoing research on the species. Key topics covered include the numerous genetic and genomic resources, available tools, the identified genes and quantitative trait locus (QTL) identified, and there is a particular emphasis on domestication. It is a valuable resource for students and researchers interested in the genetics and genomics of the common bean and legumes in general.
