“…() advocated the development of crops tolerant to salinity as a strategy to overcome this enduring problem. Since then, there have been numerous reports and reviews dealing with the development of salt‐tolerant crops (Epstein , Richards , Shannon and Qualset , Staple and Toennissen , Shannon , Foolad , , , Munns et al. , Ashraf et al.…”

Crop salt tolerance (ST) is a complex trait affected by numerous genetic and non-genetic factors, and its improvement via conventional breeding has been slow. Recent advancements in biotechnology have led to the development of more efficient selection tools to substitute phenotypebased selection systems. Molecular markers associated with genes or quantitative trait loci (QTLs) affecting important traits are identified, which could be used as indirect selection criteria to improve breeding efficiency via marker-assisted selection (MAS). While the use of MAS for manipulating simple traits has been streamlined in many plant breeding programmes, MAS for improving complex traits seems to be at infancy stage. Numerous QTLs have been reported for ST in different crop species; however, few commercial cultivars or breeding lines with improved ST have been developed via MAS. We review genes and QTLs identified with positive effects on ST in different plant species and discuss the prospects for developing crop ST via MAS. With the current advances in marker technology and a better handling of genotype by environment interaction effects, the utility of MAS for breeding for ST will gain momentum.

“…al., 2006). Foolad (2007) observed that heat stress due to high temperature becomes a major limiting factor for field production of tomatoes. Heat stress as a result of high temperature during growing season is detrimental to growth and reproductive development which reduces fruit size, yield and fruit quality (Abdul-Baki, 1991, Dane et al, 1991, Wessel-Beaver and Scott, 1992, Scott, 2000.…”

rainy season to estimates heterosis for fruit yield and heat tolerance traits of tomato under field conditions. The experiment comprised two heat tolerant (Icrixina and Rio Grande) and four heat susceptible tomato (Tima, Tropimech, Petomech and Roma Savana) which were crossed Journal of Agricultural Studies ISSN 2166-0379 2018 http://jas.macrothink.org 50 using half diallel mating design in the screen house. The resultant 15 hybrids, their parental lines along with four checks were laid out in partially balanced lattice design with three replications. Analysis of variance revealed significant variation among the genotypes for all traits except fruit diameter and cell membrane thermostability, indicating sufficient variability existed among the genotypes. The cross combinations Icrixina × Rio Grande, Icrixina × Tima, Icrixina × Roma Savana and Icrixina × Petomech were found heterotic over better parent for fruit yield and heat tolerance traits (Number of branches per plant, number of clusters per plant, number of flowers per cluster, number of fruits per cluster, number of fruits per plant, percentage fruit set and chlorophyll content) among the hybrids. These hybrids were superior over better parent have the potentiality to be exploited for developing commercial heat tolerant tomato hybrid under field conditions.
