Hybridity has a greater effect than paternal genome dosage on heterosis in sugar beet (Beta vulgaris)

BMC Plant Biology, 2018
Background The phenomenon of heterosis is critical to plant breeding and agricultural productivity. Heterosis occurs when F1 hybrid offspring display quantitative improvements in traits to levels that do not occur in the parents.

Induction of Synthetic Apomixis in Two Sorghum Hybrids Enables Seed Yield and Genotype Preservation Over Multiple Generations

Plant Biotechnology Journal, EarlyView.
ABSTRACT Induction of apomixis, or clonal reproduction through seed, could economise commercial hybrid seed production and enable smallholder farmers to save and sow hybrid seed. Here, we demonstrate the synthetic induction of apomixis in two sorghum hybrids and show that the clonal hybrid seed can be maintained across multiple seed generations.

Heterosis analysis for grain yield traits in Maize (Zea mays L.)

Electronic Journal of Plant Breeding, 2018
In the present study 6 inbreds were used as parents to make crosses in all possible cross combination in full diallel fashion to obtain total 30 possible F1 hybrids. These 30 F1’s were subjected to heterosis analysis for midparental, heterobeltiosis and

Chromatographic separation and identification of some peptides in partial hydroylsates of gelatin [PDF]

, 1953
Recently we have been engaged in a study of the chemical structure of collagen and gelatin with the object of determining the sequence of the amino acid residues in the polypeptide chains of these proteins.

Developing an Efficient System for Hybrid Rice Seed Production Using Partial Male Sterility

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient production of hybrid rice seeds requires male sterility systems to overcome the challenges of self‐pollination. In this study, we identified male gametic transfer defect (GTrD)5 and GTrD9 as essential genes for the process of male gamete transmission in rice.

Natural Variation of TaSG‐D1‐TaWRKY53 Module Regulates Heading Date in Wheat

Plant Biotechnology Journal, EarlyView.
ABSTRACT Heading date is a critical determinant of regional adaptation and yield potential. Here, we identify an E286K substitution in TaSG‐D1, encoding an STKc_GSK3 kinase, which delays heading date in wheat. Mechanistically, this substitution strengthens the physical interaction between TaSG‐D1 and TaWRKY53 and enhances the phosphorylation of ...

A method for genotyping elite breeding stocks of leaf chicory (Cichorium intybus L.) by assaying mapped microsatellite marker loci [PDF]

, 2015
BACKGROUND: Leaf chicory (Cichorium intybus subsp. intybus var. foliosum L.) is a diploid plant species (2n = 18) of the Asteraceae family. The term "chicory" specifies at least two types of cultivated plants: a leafy vegetable, which is highly ...

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.

Estimation of heterosis in pearl millet [Pennisetum glaucum (L.)] for yield and quality traits

Electronic Journal of Plant Breeding, 2016
Five CMS lines were crossed with nine testers in a line x tester design to study the extent of heterosis in pearl millet for yield and quality traits. Heterosis was observed in both directions for most of the characters.
