Heterosis for yield and grain quality parameters in basmati rice (Oryza sativa L.)

Electronic Journal of Plant Breeding, 2020
In the present study, heterobeltiosis and standard heterosis were estimated on 36 F1s obtained through half-diallel mating design for yield and quality traits.

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.

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

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Determination of Heterotic Groups and Heterosis Analysis of Yield Performance in indica Rice

Rice Science, 2018
To compare the heterosis levels among various groups of parental lines used extensively in China, identify foundational heterotic groups in parental pools and understand the relationship between genetic distance and heterosis performance, 16 parental ...

Comparing Cold Tolerance of sorghum (S. bicolor) A1 and A2 Cytoplasm‐Based Hybrids

Plant Breeding, EarlyView.
ABSTRACT Systematic exploitation of heterosis via breeding of F1 hybrids is a major contributor to genetic gain in many major crops, including sorghum (Sorghum bicolor L. Moench). Different cytoplasmic male sterility (CMS) systems have been identified for controlled F1 hybrid seed production in sorghum, with the so‐called A1 and A2 CMS systems being ...

Gene action, combining ability and standard heterosis for seed cotton yield and fibre quality components in upland cotton

Electronic Journal of Plant Breeding
Twelve parental genotypes and twenty F1 hybrids developed in a Line x Tester fashion were used in the present study to estimate gene action, combining ability and standard heterosis for eleven quantitative and five quality traits in cotton. All the traits studied exhibited greater SCA variance than GCA except days to fifty per cent flowering suggesting

Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

Plant Breeding, EarlyView.
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

Heterosis studies for quantitative traits in sesame (Sesamum indicum L.) [PDF]

Electronic Journal of Plant Breeding, 2015
A study was conducted in sesame (Sesamum indicum L.) at Department of Genetics and Plant Breeding, N.M. College of Agriculture, NAU, Navsari (Gujarat) to assess the extent of heterosis for eleven quantitative traits.

Standard heterosis and phenotypic correlation studies on yield contributing traits and quality parameters in tomato (Solanum lycopersicum L.)

Electronic Journal of Plant Breeding
Hybrids show better performance than varieties in terms of yield and quality. Heterosis breeding provides a way to develop hybrids to uplift yield and quality. In the current study, 21 hybrids generated through line × tester mating design were evaluated along with the standard check, Arka Rakshak, in a randomized block design to investigate the ...
