Heterosis studies for yield and fibre quality traits in American cotton (Gossypium hirsutum L.)

Electronic Journal of Plant Breeding, 2020
In the present study forty five intra-hirsutum hybrids along with their parents and standard check were evaluated to estimate the magnitude of heterosis for yield and fibre quality traits at Regional Agricultural Research Station, Lam, Guntur during ...

Combining ability and heterosis for grain yield, fodder yield and other agronomic traits in sorghum [Sorghum bicolor (L.) Moench] [PDF]

, 2015
Forty five hybrids derived from a diallel mating design of ten parents and one standard check PUSA CHARI-121 were evaluated for general and specific combining ability effects and standard heterosis for grain yield/plant, dry fodder yield/plant, days to ...

Dynamics of Gene and Allelic Expression During Modern Hybrid Maize Breeding

Plant Biotechnology Journal, EarlyView.
ABSTRACT Maize breeding has greatly improved yield through single‐cross hybrids, but the underlying gene regulatory changes remain unclear. This study analysed transcriptomes of landmark maize hybrids and their parents across developmental stages and planting densities.

Combining Ability and Heterosis for Grain Yield and its Component Traits in Rice(Oryza sativa L.)

Notulae Scientia Biologicae, 2013
The nature and magnitude of heterosis and combining ability was studied in 18 F1 hybrids involving three CMS lines and six testers using line × tester analysis. The analysis of variance for combining ability of all the traits showed that variances due to

Engineering a Gibberellin‐Switchable Dual‐Use Line Based on Ent‐Kaurene Oxidase Gene ZmKO1 Enables Two‐Line Hybrid Seed Production in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Male‐sterile systems are pivotal for maize hybrid seed production, yet existing systems are constrained by significant limitations. Here, we identified a novel single‐gene‐controlled recessive genic male sterility (GMS) mutant, defective in filament elongation 1 (def1), which exhibits non‐elongated filaments, unopened glumes, and non‐exserted ...

Rice EMF3 Alleles Adjust Flower Opening Time to Enhance the Seed Setting Rate Under High Temperature Stress

Plant Biotechnology Journal, EarlyView.
ABSTRACT To safeguard global food security against rapid population growth and a warming world, the effective genetic improvement of cereals is imperative. Flower opening time (FOT) critically affects the seed setting rate. In this study, we identified a gene, EARLY‐MORNING FLOWERING 3 (EMF3), in which single‐nucleotide substitutions strongly modulate ...

Quantitative studies on heterosis and inbreeding depression in maize (Zea mays l.) [PDF]

, 2018
The present investigation was carried out for studying heterosis and inbreeding depression of twenty eight hybrids (F1 ? s) and their F2 ? s made by crossing of eight maize inbreds in all possible cross combinations excluding reciprocal.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.
