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.

Callose deficiency modulates plasmodesmata frequency and extracellular distance in rice pollen mother and tapetal cells

Fertilization relies on pollen mother cells able to transition from mitosis to meiosis to supply gametes. This process involves remarkable changes at the molecular, cellular and physiological levels, including (but not limited to) remodelling of the cell

Identification of Genetic Loci Conveying Resistance to Fusarium oxysporum f. sp. ciceris Race 0 in Chickpea

Plant Breeding, EarlyView.
ABSTRACT Chickpea (Cicer arietinum L.) is a legume that is widely consumed around the world due to its nutritional content. Fusarium oxysporum f. sp. ciceris is a serious, destructive pathogen that causes fusarium wilt disease and affects chickpea production.

The Physiology and Biochemistry of Meiosis in the Anther

, 1987
Publisher Summary This chapter discusses the physiology and biochemistry of meiosis in the anther. To understand events in both the nucleus and cytoplasm of male meiocytes of higher plants, developmental changes are considered at the point at which meiosis is initiated in the archesporial tissue.

A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Utilization of the litchi male-sterile line ‘MS1’—assisting in the selection of suitable harvesting periods for pollen donors for hybridization

Frontiers in Plant Science
Litchi (Litchi chinensis Sonn.), an important fruit originating in China, has received increasing attention for improving breeding efficiency in recent years due to the growing adoption of hybridization.

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Genetic Analysis of East African Sorghum Genotypes for Yield Components and Iron and Zinc Composition

Plant Breeding, EarlyView.
ABSTRACT Sorghum [Sorghum bicolor (L.) Moench] is a vital cereal crop in dry regions worldwide. However, in sub‐Saharan Africa (SSA), grain yields from currently grown varieties remain low (< 1 ton/ha) and exhibit variable nutrient composition. Therefore, the objective of this study was to undertake a genetic analysis of selected East African‐adapted ...
