Information on gene action controlling the inheritance of quantitative traits is essential for selecting parents hybridization and multiline varieties. Twenty hybrids obtained through 5 × diallel mating with their were established Teaching Research Farm, Federal University Agriculture, Abeokuta, Nigeria, in September 2018 using Randomized Complete Block Design three replicates. The plants observed numbers days to 50% flowering, plant height at stem girth, number branches per plant, maturity, fruits fruit weight, length, width, yield plant. Data subjected variance analysis, General Specific Combining abilities estimated, effects parameter ratios done Hayman's method. Mid- better-parent heterosis estimated Allard's procedure. Genotype 'NGB00356' was most desirable parent earliness while hybrid 'NGB00347' best 'NGB00356', its significant positive general combining ability value can be used as a program improvement okra.

Since their inception, the French academic organizations dedicated to agricultural research have developed plant collections in genebanks, often within a public–private framework, support study of traits and development new improved varieties. In addition, since 2000s, centre for genomic resources has also been established France. Over last 20 years, this decentralized system, consisting genebanks resources, supported by national coordination structure.

Advancements in molecular approaches have been utilized to breed crops with a wide range of economically valuable traits develop superior cultivars. This review provides concise overview modern breakthroughs plant production. Genotyping and high-throughput phenotyping methods for predictive breeding are briefly discussed. In this study, we explore contemporary techniques producing desirable crop varieties. These include cisgenesis, clustered regularly interspaced short palindromic repeat (CRISPR/Cas9) gene editing, haploid induction, de novo domestication. We examine the speed approach—a strategy cultivating plants under controlled conditions. further highlight significance technologies efficiently utilizing agricultural resources production urban areas. The deciphering genomes has led development extensive DNA markers, quantitative trait loci (QTLs), pangenomes associated various traits. shift genotypic selection considerably expedites process.

Abstract Loss of genetic diversity in elite crop breeding pools can severely limit long‐term gains and ability to make new traits, like heat tolerance, that are becoming important as the climate changes. Here, we investigate propose potential program applications optimal haplotype stacking (OHS), a selection method retains useful population. OHS selects sets candidates containing, between them, segments with very high segment values for target trait. We compared performance OHS, similar called population value (OPV), truncation on genomic estimated (GEBVs), contribution (OCS) stochastic simulations recurrent founder wheat genotypes. After 100 generations intercrossing selection, OCS had exhausted diversity, while considerable remained Gain under these ultimately exceeded from or OCS. achieved faster when size was small, many progeny per cross. A promising hybrid strategy, involving single cycle first generation followed by substantially improved gain performed similarly The results this study provide initial insights into where could be incorporated programs.

The use of plant genetic resources (PGR)-wild relatives, landraces, and isolated breeding gene pools-has had substantial impacts on wheat for resistance to biotic abiotic stresses, while increasing nutritional value, end-use quality, grain yield. In the Global South, post-Green Revolution yield gains are generally achieved with minimal additional inputs. As a result, production has increased, millions hectares natural ecosystems have been spared. Without PGR-derived disease resistance, fungicide would easily doubled, massively selection pressure resistance. It is estimated that in wheat, billion liters application avoided just since 2000. This review presents examples successful PGR including relentless battle against rust epidemics/pandemics, defending diseases jump species barriers like blast, biofortification giving nutrient-dense varieties novel variation improving polygenic traits climate resilience. Crop genepools urgently need be diversified increase yields across range environments (>200 Mha globally), under less predictable weather stress pressure, input efficiency.

Crop production is becoming an increasing challenge as the global population grows and climate changes. Modern cultivated crop species are selected for productivity under optimal growth environments have often lost genetic variants that could allow them to adapt diverse, now rapidly changing, environments. These present in their closest wild relatives, but so less desirable traits. How preserve effectively utilize rich resources relatives offer while avoiding detrimental maladaptive contributions a central ongoing improvement.
