Peanut is an important and nutritious agricultural commodity a livelihood of many small-holder farmers in the semi-arid tropics (SAT) world which are facing serious production threats. Integration genomics tools with on-going genetic improvement approaches expected to facilitate accelerated development improved cultivars. Therefore, high-resolution genotyping multiple season phenotyping data for 50 agronomic, disease quality traits were generated on ‘reference set’ peanut. This study reports...
Abstract Field experiments were conducted to evaluate eight different integrated crop management (ICM) modules for 5 years in a maize-wheat rotation (M WR ); wherein, ICM 1&2 -ˈbusiness-as-usualˈ (conventional flatbed maize and wheat, 3&4 -conventional raised bed (CT RB ) wheat without residues, 5&6 -conservation agriculture (CA)-based zero-till (ZT) with the 7&8- CA-based ZT residues. Results indicated that 7&8 produced significantly (p < 0.05) highest grain yield (5...
Abstract Background The demand of maize crop is increasing day by day, hence to reduce the production and gap, there a need extract high yielding parental lines improve per se yield hybrids, which could help enhance productivity in crops. Methods results present investigation was carried out select best medium maturing inbred lines, among set 118 lines. Based on Duncan multiple range test, 16 were selected basis its flowering time. molecular diversity using SSR markers linked heterotic QTL...
Delayed sowing of maize hybrids could exacerbate the capability maximizing yield potential through poor crop stand, root proliferation, nutrient uptake, and dry matter accumulation coupled with inadequate partitioning assimilates. This study appraised performance five recent viz., PMH-1, PJHM-1, AH-4158, AH-4271, AH-8181 under timely late sown conditions irrigated semi-arid ecologies. Timely had grain stover yields advantage 16-19% 12-25%, respectively over hybrids. The advanced AH-4271...
ABSTRACT The nutritional quality of peanut ( Arachis hypogaea L.) products depends on the protein content, oil and composition oil. Low genetic variability has been a major bottleneck in enhancement these traits commercial cultivars. present study was conducted to identify stable genotypes with better good agronomic performance for use future breeding programs. 184 mini core accessions four control cultivars were evaluated two seasons at locations one location. Significant genotypic genotype...
With 2 figures and 3 tables Abstract High oleic acid (O) low linoleic (L) make peanut oil ideal for longer storage better human health. Among the ICRISAT mini core collection accessions, ranged from 33.60% to 73.54%. Accessions belonging ssp. hypogaea had higher (54.16%) compared with those of fastigiata (45.70%). An O : L ratio up 6.93 was found among . Additional varieties, mutants, germplasm lines breeding within range accessions. Mutations in ahFAD2A , which along its homologous gene,...
Grain yield is influenced by environmental interactions. Multi-Environment Testing (MET) vital to validate the performance of hybrids. To understand grain and stability hybrids across major corn (Zea mays L.) growing regions in India, thirty field were grown five diverse environments Randomized Complete Block Design (RCBD) during Kharif, 2021. The data from all showed highly significant (p<0.01) variance due genotype, environment, G×E interaction. AMMI (Additive Main Effects...
Context Establishment of true heterotic pattern in maize germplasm can increase the efficiency hybrid breeding. Heterosis is dependent on genetic diversity parents and extent dominance at different loci. Estimation through use molecular markers routine practice Aims The present study was designed to test whether simple sequence repeat (SSR) linked yield-contributing traits are more reliable for grouping than random SSRs. Methods Diallel crosses developed among 19 inbred lines were evaluated...
Kernel row number (KRN) is an important yield component trait with a direct impact on the productivity of maize. The variability in KRN influenced by inflorescence meristem size, which determined CLAVATA-WUSCHEL pathway. A CLAVATA receptor-like protein, encoded FASCIATED EAR2 (fea2gene), enhances growth and thus involved determination KRN. amplicon sequencing-based method was employed to dissect allelic variation fea2 gene tropical field corn.
The present work was conducted to study the genetic variation and identification of microsatellite markers linked rust resistance in groundnut.An F 6 mapping population three backcross populations (BC 1 4 , BC 2 3 ) were developed from a cross between susceptible parent GPBD-5 resistant GPBD-4.There highly significant differences among recombinants for reaction rust.A little difference observed PCV GCV rust.High heritability coupled with high advance as per cent mean populations.Bulk...
In recent years, the fall armyworm,
The selection of diverse parents is a prerequisite for the exploitation grain yield heterosis and real challenge to maize breeders. Heterotic grouping assists breeder in selecting such parents, which reduces number crosses be made by avoiding intra-group crosses. An investigation was carried out evaluate 54 inbreds along with two testers (LM 13 LM14) 108 hybrids derived using hybrid checks during rainy post-rainy seasons 2019. based on three biometrical methods, viz., Specific Combining...
Genotype (G) × environment (E) interaction is very important for the evaluation of cultivars in breeding programmes. Present study was conducted to assess effect and yield stability 68 quality protein maize (QPM) hybrids at three test environments [Begusarai (E1), Udaipur (E2) Karim Nagar (E3)] randomized block design (RBD). Data analysed using additive main effects multiplicative (AMMI) genotype by (GGE) biplot methods. The variation genotypes, interactions (G×E) highly significant. Maximum...
A total of 268 recombinant inbred lines (RILs) were evaluated for genetic variability yield, nutritional and oil quality traits under two consecutive seasons at locations.Analysis showed that exists in the population as well yield component traits.Majority components governed by additive effects.The not affected environmental factors simple phenotypic selection ensures increased performance genotypes.Yield moderate to high heritability but with great influence environment.
Sustainable feeding of a growing population with nutritional security in the era climate change is leading challenge facing adeveloping nation. Field corn one those crops that can help achieve this goal due to its high productivity and wide adaptation. There scope for further improving field by targeting component traits such as kernel row number (KRN). In present investigation, displayed significant variation well asa positive correlation yield under study. The inheritance KRN trait was...
