Identification and validation of quantitative trait loci (QTL) governing desired phenotype target is a prerequisite to implement marker-assisted selection in any crop including dolichos bean. Under this premise, we used two mapping populations (MPs) detect cross population validate QTL controlling fresh pod yield. One the MPs consisted F2 individuals (MP1) derived from crossing elite genotypes, second MP random RILs (MP2) different pair genotypes. The MP1 MP2 were genotyped using polymorphic...
This review paper delves into the future of plant breeding by examining advancements and challenges in field. The introduction provides an overview historical evolution highlights its relevance addressing contemporary global such as food security climate change. subsequent section explores transition from conventional to molecular techniques, showcasing latest marker-assisted selection, genomic gene editing. Moreover, elucidates significance stress-tolerant adaptable crops combat effects...
Abstract Maize is an important agricultural crop ensuring food and nutritional security throughout the globe. It highly sensitive to many of biotic abiotic stresses, among them, drought most severe stress limiting maize production. Climate change tends worsen this scenario by changing precipitation patterns decreasing water availability. Hence, present study was undertaken identify drought‐tolerant inbred lines under well‐irrigated managed conditions in field toward developing...
Background: Allocation of resources only to a few promising segregating populations that are likely result in high frequency transgressive recombinant inbred lines (RILs) for use as pure-line cultivars would help enhance efficiency breeding self-pollinated crops including dolichos bean. The an objective criterion identify is therefore assumes importance. prediction RILs could be derived from advanced generations crosses one such criterion. Methods: We predicted the transgressed better parent...
Dolichos bean is grown in environments with short and long crop growth seasons. Development deployment of cultivars flowering time (FT) that matches prevailing season help maximize their productivity the to which they are targeted. Dependable knowledge on genetic basis FT enables use most appropriate selection strategy breed desired FT. We unraveled by detecting QTL controlling using SSR markers following selective genotyping (SGS) F2 mapping population (MP). evaluated effectiveness SGS as...
Background: Determinate growth habit is farmer-preferred trait in dolichos bean. Fresh pods are harvestable and marketable economic products For ready acceptance of determinate cultivars, they should be high fresh pod yielding background. Empirical evidence based on non-isogenic backgrounds indicated that genotypes with indeterminate produce greater yield than those habit. However, confounding effects the genes other controlling cannot ruled out. Near isogenic lines (NILs) ideal genetic...
Identification of markers linked to loci controlling economically important traits, including growth habits, helps the selection genotypes with desired habits at seedling stage itself in crops, no exception dolichos bean. Near isogenic lines (NILs) differing for a target locus are most appropriate genetic resources identification dependable genomic use marker-assisted genes habit. In present study, we found that 30 F2:5 progenies derived from cross between determinate and indeterminate...
Abstract Early elimination of poor crosses based on an objective criterion allows increased allocation resources only to a few promising for identifying superior recombinant inbred lines (RILs) use as pure-line cultivars in self-pollinated crops. generation (F 2:3 ) prediction frequency RILs that could be derived from advanced generations is one such criterion. We predicted the transgressive two horse gram (namely HPKM 320 × CRIDA18-R and IC 361290 Palem 1) primary branches per plant, pods...
Abstract Development of high yielding cultivars with determinate growth habit in photoperiod insensitive (PIS) background is one the major objectives breeding grain legumes crops including dolichos bean. A thoroughly validated genetic basis a prerequisite for bean PIS background. Based on published reports by researchers our laboratory and those others, unpublished data, we hypothesized that number mode action genes controlling differ degree sensitivity material used to investigate...
Abstract Mungbean yellow mosaic virus (MYMV) disease is one of the most devastating biotic constraints mungbean production in India. Dependable knowledge on number and mode action genes controlling resistance to MYMV keys develop resistant cultivars. The F 1 s four crosses derived from genotypes × highly susceptible genotype, their parents, 2 3 along with a check were screened for responses following infector-row technique under natural infection conditions. A good fit population segregation...
Abstract Growth habit is a plant architectural trait in grain legumes with no exception of horse gram. Determinacy and indeterminacy are the two types growth habits reported Relative advantages depend on production systems to which cultivars targeted. Dependable information genetics provide clues for adopting most appropriate selection strategy breed high yielding gram varieties desired habit. Taking cues from past studies, we hypothesize that controlled by genes displaying inhibitory...
Background: Mere presence of phenotype-based quantitative traits (QT’s) variability is less significance in breeding crops including horse gram. A dependable knowledge on relative contribution genetic and non-genetic sources the QT’s organization terms similar diverse groups genotypes useful selection most desired parents to generate populations formulating appropriate strategies breed improved gram cultivars. The objectives study were (i) quantify (ii) identify trait-specific accessions a...
Abstract In common with other grain legumes, the growth habit in horse gram is one of domestication-driven adaptive traits. Horse exhibits determinate and indeterminate types habits. Determinate genotypes have non-overlapping vegetative reproductive phases combined a compact which enables farmers to produce intercropping multiple cropping systems, practice for sustainable agriculture production. Also, synchronous flowering, pod development maturity enable mechanical harvesting. Empirical...
Growth habit (indeterminate/determinate) is one of the evolutionarily shaped, economically important plant architectural traits in grain legumes, including horse gram. Arabidopsis AtTFL1 and AtLFY genes their homologs other legume species are known to control growth habit. Taking cues from highly conserved domains protein encoded by TFL1 LFY genes, we isolated gram (MuTFL1 MuLFY) using reported degenerate primers designed domains. MuTFL1 MuLFY were sequenced Sanger?s sequencing protocol. The...
