Estimation of heterosis for earliness, yield and yield attributing traits in chilli (Capsicum annuum L.)

Electronic Journal of Plant Breeding, 2018
The present investigation was carried out to estimate the magnitude of heterosis over mid parent, better parent and standard checks (Tejaswini and Indam-5) for earliness, fruit yield and yield attributing traits in chilli (Capsicum annuum L.) and ...

ASSOCIATION OF HYBRID PERFORMANCE, HETEROSIS AND DOMINANCE TYPES IN PEPPER(Capsicum annuum, L.) [PDF]

Journal of Plant Production, 2014
                During successive summer seasons of 2008 to 2011, this study was conducted at Middle Delta region. Eight sweet pepper breed lines were used in half-diallel cross mating design to produce 28 F1 pepper hybrids.

ZmMS1 coordinates ROS homeostasis, lipid allocation, and male fertility for maize breeding applications

Journal of Integrative Plant Biology, EarlyView.
The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

Heterosis and Combining ability for yield and quality traits in Quality Protein Maize (Zea mays L.)

Electronic Journal of Plant Breeding, 2016
A study of diallel analysis (excluding reciprocal cross) involving 10 maize inbreds (P1 to P10) was carried out to identify high heterotic crosses and their relationship in terms of general and specific combining ability (GCA and SCA) for yield and ...

Estimation of Standard Heterosis Over Environments for Fruit Yield and Its Attributes in Tomato (Solanum lycopersicum L.)

Journal of Advances in Biology & Biotechnology
Heterosis breeding has shown to be a promising technique for enhancing crop yields. It allows for the early identification of superior or potential crosses, which is essential for managing the material efficiently and productively in subsequent generations. An experiment was conducted to evaluate 40 genotypes in three different environments.

Smart double‐screening system of propagating male‐sterile lines for maize hybrid seed production

Journal of Integrative Plant Biology, EarlyView.
The Seed and Seedling Marker Method double‐screening system for maize hybrid seed production integrates Ms45‐mediated fertility restoration, Mn1/Sh1‐RNAi‐based seed selection, and Lc‐based seedling selection. It thus enables efficient, high‐purity propagation of male‐sterile lines by combining fertility maintenance with sequential visual selection at ...

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

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 ...
