Acta Societatis Botanicorum Poloniae, 2011 Peat-bog pine Pinus uliginosa Neumann has become extinct or rare in many parts of Europe. We have investigated the levels of genetic variation and inbreeding in seeds collected from a highly endangered reserve of this species in Poland, using allozymes ...

Evolution of crop phenotypic spaces through domestication
New Phytologist, EarlyView.Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

031 Rate of Natural Outcrossing in Cucumber Isolation Blocks [PDF]
HortScience, 1999 Cucumber (Cucumis sativus L.) populations often are intercrossed after each selection cycle using bees in isolation blocks. Previous research showed the rate of natural outcrossing in monoecious cucumber inbreds was 36%. The objective of this experiment was to determine whether the rate of natural outcrossing could be increased using hormones, plot ...

Pollen Dispersal and Pollination Patterns Studies in Pati Kopyor Coconut using Molecular Markers
CORD, 2015 Parentage analysis has been used to evaluate pollen dispersal in Kopyor coconut (Cocos nucifera L.). Investigations were undertaken to elucidate (i) the dispersal of pollen, (ii) the rate of self and out-crossing pollination, and (iii) the distance of ...

Rice, 2020 Background Stigma exsertion rate (SER) is a key determinant for the outcrossing ability of male sterility lines (MSLs) in hybrid rice seed production. In the process of domestication, the outcrossing ability of cultivated rice varieties decreased, while ...

Gametocyte sex ratios as indirect measures of outcrossing rates in malaria
Parasitology, 1992 The frequency of recombination between unlike genotypes is central to understanding the generation of genetic diversity in natural populations of malaria. Here we suggest a way of investigating the problem which could complement conventional biochemical approaches to the population genetics of malaria.

Plant Biotechnology Journal, EarlyView.ABSTRACT Mango (Mangifera indica) is one of the most popular fruits cultivated in tropical and subtropical regions of the world. The availability of reference genomes helps to identify the genetic basis of important traits. Here, we report assembled high‐quality chromosome‐level genomes for the Australian mango cultivar ‘Kensington Pride’ and M ...

Levels of diversity and inbreeding in a clonal seed orchard for high-mountain ecotype of Scots Pine [PDF]
Silva BalcanicaSeed orchards are an important source of high-quality seeds for afforestation. Genetic composition of seed orchard crop was studied in a clonal seed orchard situated in Borovets, Rila Mts, which was designed for producing seed for high-mountain ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Amaranthus palmeri is one of the most troublesome invasive agricultural weeds worldwide, exhibiting super invasiveness and high resistance to conventional management strategies. Artificial microRNA‐mediated silencing technology, coupled with a nanoparticle‐mediated delivery system, represents an attractive approach for fertility control in A ...
