Outcrossing and heterozygosity rates in tropical onion populations

Comunicata Scientiae, 2022
Outcrossing and heterogosity rates are important for defining genetic conservation and breeding strategies, and these estimates are quite rare to onion. The aim of this study was to estimate cross-pollination and heterozygosity rates in tropical onion populations to guide development of new varieties.

Evaluation of Advanced Mutant Restorer Lines for Enhancing Outcrossing Rate and Hybrid Seed Production of Diverse Rice Cytoplasmic Male Sterile Lines

Agronomy, 2022
Hybrid rice seed production predominantly relies on the pollen ability of restorer lines and the stigma properties of the cytoplasmic male sterile (CMS) lines.

Genetic effects and plant architecture influences on outcrossing rate in soybean

Journal of Integrative Agriculture, 2019
Outcrossing rate is an important determinant of cytoplasmic male sterile (CMS) breeding and hybrid seed production for heterosis in soybean. Parental lines with a high outcrossing rate were screened for backcross breeding to obtain the high outcrossing ...

Outcrossing Rate and Genetic Variability in Mexican Race Avocado [PDF]

Journal of the American Society for Horticultural Science, 2020
The blooming behavior of the avocado Persea americana Mill. is a sophisticated mechanism that prevents effective self-pollination, enables close pollination, and encourages cross-pollination. However, there is no information on outcrossing rate among Mexican race avocado genotypes (

Reconstruction of the High Stigma Exsertion Rate Trait in Rice by Pyramiding Multiple QTLs

Frontiers in Plant Science, 2022
Asian cultivated rice is a self-pollinating crop, which has already lost some traits of natural outcrossing in the process of domestication. However, male sterility lines (MSLs) need to have a strong outcrossing ability to produce hybrid seeds by ...

Natural outcrossing rate in Vernonia galamensis

Plant Breeding, 2004
Abstract Vernonia galamensis is a potential new industrial crop growing wild in Ethiopia. The seed oil is rich in vernolic acid, an epoxy fatty acid, which is of interest for oleochemical uses. Basic information on the reproductive system of Vernonia is still very limited.

Rate of Natural Outcrossing in Monoecious Cucumbers

HortScience, 1985
Abstract The rate of natural outcrossing in cucumber (Cucumis sativus L.) was measured at 3 locations in North Carolina, using the dominant allele for scab resistance as the marker gene. Outcrossing was measured within and between 1.5 m plots in isolation blocks.

Stability of Outcrossing Rates in Eucalyptus globulus Seedlots [PDF]

Silvae Genetica, 2004
SummaryEucalyptus globulus has a mixed mating system and selfing leads to severe inbreeding depression. Thus, outcrossing rate is an important measure of seed quality in this species. Outcrossing rates were estimated on the frequency of a rare recessive chlorophyll deficient mutant in open pollinated seed.
