TL;DR: The present review aims to summarize a lot of information generated on classical as well as molecular breeding approaches to give an insight into the underlying mechanism of heat stress tolerance in wheat.
Abstract: Wheat is one of the primary foods for more than 40 countries and for over 35% of the global population. The increased temperature during reproductive phase known as heat stress has emerged as a serious problem. Constant or transitory high temperatures may affect the plant growth and development which may lead to diverse morphological, physiological and biochemical changes in plants ultimately decrease in yield. Every 1°C rise in temperature above 28°C during grain filling, results in yield reduction by 3-4 %. To combat, the breeding for crops with enhanced heat tolerance is of pivotal importance to ensure global food security. The understanding of the mechanisms of the heat tolerance at the reproductive stage is the prerequisite for inducing toreance in wheat in particular. During recent past, a lot of information has been generated on classical as well as molecular breeding approaches. The present review aims to summarize those published data to give an insight into the underlying mechanism of heat stress tolerance in wheat.

TL;DR: In this paper, a molecular breeding method for improving the strength and micronaire value of cotton fibers was proposed, which is specially applied to directionally improving the agronomic traits and breeding new varieties of crops (cotton).
Abstract: The invention relates to a molecular breeding method for improving the strength and micronaire value of cotton fibers, which is specially applied to directionally improving the agronomic traits and breeding new varieties of crops (cotton). By detecting the cotton fiber quality of chromosome segment introgression lines of island cotton, an introgression line IL088-A7-3 is screened, the fiber strength of which is significantly increased and the micronaire value is significantly reduced. The introgression line which is used as the non-recurrent parent is hybridized with the early maturing uplandcotton variety No.38 from the Xinjiang cotton-planting area which is used as the recurrent parent, then back-crossed in two generations and self-crossed in three generations, so as to screen a cottonnew line which is excellent in both fiber strength and micronaire value through the auxiliary selection by using molecular marking. By use of the method provided by the invention, the high-quality high-yield cotton new line 'island cotton No.3 of Nanjing agricultural university' has been bred.

TL;DR: Pigeonpea and chickpea are among the most important pulse crops grown in Asia, sub-Saharan Africa, Australia, Canada and Middle East and were almost untouched from the genomics interventions until early years of twenty first century.
Abstract: Pigeonpea and chickpea are among the most important pulse crops grown in Asia, sub-Saharan Africa, Australia, Canada and Middle East. The major production of these pulses comes from India, which is also the biggest consumer and importer. However, productivity in these pulse crops is stagnant and unacceptably low for decades, mainly due to their exposure to a number of biotic and abiotic stresses in the marginal environments. Moreover, these pulses were almost untouched from the genomics interventions until early years of twenty first century. However, last ten years have witnessed significant development and deployment of genomics for crop improvement programs. At present, thousands of simple sequence repeat (SSR) markers, millions of single nucleotide polymorphism (SNP), several cost effective genotyping platforms, many dense genetic maps, draft genomes and re-sequencing data for several hundred to thousand genomes have been developed. A number of trait associated markers have been developed and are being used in developing improved lines through genomics assisted breeding (GAB).

TL;DR: Conventional and advanced lemon breeding techniques are evaluated and discussed and emergent methods and technologies are evaluated to advance basic and applied lemon-breeding methods and to suggest directions for future research.
Abstract: Lemon ( Citrus limon L. Burm. F.; Rutaceae) is one of the most important commercial and nutritional fruits in the world. Therefore, it needs to be improved for the diverse needs of consumers and crop breeders. Breeders have attempted to eliminate undesirable characteristics in plants and develop new varieties with desired characteristics that meet the needs of farmer and consumer by using different breeding techniques. In lemon breeding, seedlessness or with fewer seeds, resistance or tolerance to biotic and abiotic stress, acidity, yield, quality and early- or late-ripening are the most desired features and topics. Lemon improvement through conventional breeding is time consuming and cumbersome. Moreover, it has obstacles such as the high degree of heterozygosis due to frequent gene mutations either in reproductive or somatic cells and long juvenility in conventional breeding. In recent years, both conventional and molecular breeding techniques have been used to obtain new lemon varieties. In particular, the use of molecular techniques is rapidly increasing in an attempt to reduce the difficulties faced in conventional breeding like specific reproductive physiology of lemon and protracted length of time. In this chapter, conventional and advanced lemon breeding techniques are evaluated and discussed. In addition, emergent methods and technologies are evaluated to advance basic and applied lemon-breeding methods and to suggest directions for future research.
