Unlabelled: The genetic trade-offs among complex traits are often witnessed in rice, however, very little is known about the contributing genes and mechanisms to exploit in breeding programmes. Here, we aimed to understand the genetic trade-offs among disease resistance, quality, and yield traits employing genome-wide association mapping. In all, 78 common marker-trait associations (MTAs) were identified for the targeted traits.

The best approach to enhance drought tolerance in rice varieties is to identify and introgress yield QTLs with major effects. The Association mapping approach helps in the identification of genomic regions governing physiological, yield and yield attributes under moisture and heat stress conditions in diverse collections of crop germplasm, based on historic recombination events and linkage disequilibrium across the genome.

CRISPR/Cas9 based genome editing is an effective and useful tool adopted from the bacterial immune response system for altering specific, pre-determined DNA sequences in eukaryotes. Such targeted changes are finding wide application in human health as well as in precision breeding of crop plants for improved traits.

To identify promising genotypes for grain Zn, a total of 40 genotypes consisting 20 rice landraces, and 20 released high yielding rice varieties were evaluated in three environments (wet seasons 2014, 2015 and 2016) for nine traits including days to 50% flowering (DFF), plant height (PH), panicle length (PL), total number of tillers (TNT), single plant yield (SPY), Fe and Zn in brown (IBR, ZBR) and polished rice (IPR, ZPR). Additive Main Effect and Multiplicative Interaction (AMMI), Genotype and Genotype × Environment Interaction (GGE) analyses identified genotypes G22 (Edavankudi Pokkali), G17 (Taraori Basmati), G27 (Chittimuthyalu) and G26 (Kalanamak) stable for ZPR and G8 (Savitri) stable for SPY across three environments.

Response of castor tissues to in vitro culture is poor which necessitated this study on understanding the molecular basis of organogenesis in cultured tissues of castor, through de novo transcriptome analysis and by comparing with jatropha and sunflower having good regeneration ability. Transcriptome profiling analysis was carried out with hypocotyl explants from castor, jatropha and cotyledons from sunflower cultured on MS media supplemented with different concentrations of hormones.

This study aims at uncovering these promising alleles of six key genes influencing the yield, such as DEP1, Ghd7, Gn1a, GS3, qSW5 and sd1 by targeted resequencing of the 200 rice genotypes.
