Ragsdale, Makenzie E. Mabry, Xinshuai Qi, Kevin A. Bird, Pablo Velasco, Hong An, J. Chris Pires, Eve Emshwiller Abstract The study of domestication contributes to our knowledge of evolution and crop genetic resources. Human selection has shaped wild Brassica rapa into diverse turnip, leafy, and oilseed crops. Despite its worldwide economic importance and potential as a model for understanding diversification under domestication, insights into the number of domestication events and initial crop(s) domesticated in B. rapa have been limited due to a lack of clarity about the wild or feral status of conspecific non-crop relatives. To address this gap and reconstruct the domestication history of B. rapa, we analyzed 68,468 genotyping-by-sequencing-derived SNPs for 416 samples in the largest diversity panel of domesticated and weedy B. rapa to date. To further understand the center of origin, we modeled the potential range of wild B. rapa during the mid-Holocene. Our analyses of genetic diversity across B. rapa morphotypes suggest that non-crop samples from the Caucasus, Siberia, and Italy may be truly wild, while those occurring in the Americas and much of Europe are feral. -

www.nature.com/scientificreports OPEN Demographic analysis of arrhenotokous parthenogenesis and bisexual reproduction Received: 10 October 2017 Accepted: 8 February 2018 of Frankliniella occidentalis Published: xx xx xxxx (Pergande) (Thysanoptera: Thripidae) Tianbo Ding1, Hsin Chi2, Ayhan Gökçe2, Yulin Gao3 & Bin Zhang 1 Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is a serious pest that is capable of bisexual and arrhenotokous reproduction. In arrhenotokous reproduction, virgin females initially produce male ofspring; later, when their sons are sexually mature, the mothers begin bisexual reproduction by carrying out oedipal mating with their sons. Because a virgin female produces many male ofspring before oedipal mating occurs, multiple oedipal mating is common. In this study, we investigated the efect of multiple oedipal mating on the population growth of F. occidentalis by using the age-stage, two-sex life table theory. In the arrhenotokous cohorts, all unfertilized eggs developed into males. In the bisexual cohorts, the ofspring sex ratio was signifcantly female biased with the mean number of female ofspring and male ofspring being 72.68 and 29.00, respectively. These were the same as the net reproductive rate of female ofspring and male ofspring. In arrhenotokous cohorts, the number of males available for oedipal mating signifcantly afected the production of female ofspring. The number of female ofspring increased as the number of sons available for oedipal mating increased. Correctly characterizing this unique type of reproduction will provide important information for predicting the timing of future outbreaks of F. occidentalis, as well as aiding in formulating successful management strategies against the species. Te western fower thrips (WFT), Frankliniella occidentalis (Pergande) (Tysanoptera: Tripidae), is one of the most economically important insect pests of many horticultural crops especially in greenhouses1,2. -

The treatments consisted of combinations of two rapeseed genotypes (Hyola 61 and Hyola 433), three pollination tests (uncovered area, covered area without insects and covered area containing a single colony of Africanized Apis mellifera honeybees) and two sowing dates (May 25th, 2011 and June 25th, 2011). The presence of Africanized honeybees during flowering time increased the productivity of the rapeseed. -
The Effect of Plant Development on Thrips Resistance in Capsicum
Arthropod-Plant Interactions https://doi.org/10.1007/s11829-018-9645-6 ORIGINAL PAPER The effect of plant development on thrips resistance in Capsicum Pauline van Haperen1,2 · Roeland E. Voorrips1 · Joop J. A. van Loon2 · Ben Vosman1 Received: 28 March 2018 / Accepted: 25 September 2018 © The Author(s) 2018 Abstract Western flower thrips [Frankliniella occidentalis (Pergande)] is a worldwide pest insect that causes damage in pepper cul- tivation, so growers would benefit from host plant resistance. The objectives of this study were (1) to evaluate the effect of plant age on thrips resistance using nine Capsicum accessions with different levels of thrips resistance at three different plant ages, and (2) to study the effect of leaf age on thrips resistance in a resistant and a susceptible pepper accession. The fraction of first instar larvae that did not develop into second instar was used as a measure for thrips resistance. Our results show that plants start to develop thrips resistance when they are between 4 and 8 weeks old. This transition was most marked on the resistant accession CGN16975, on which about 50% of the L1 larvae developed into the next stage on 4-week-old plants, whereas none of them developed beyond the L1 stage on 8- or 12-week-old plants. Furthermore, it is shown that youngest fully opened leaves of the resistant accession CGN16975 are significantly more resistant to thrips than older leaves; 89% of the L1 larvae did not develop into the next stage on the youngest leaves, whereas 57% did not develop beyond the L1 stage on the oldest leaves. -

Ornamental Cabbage and Kale, Brassica Oleracea in the Fall, Chyrsanthemums and Pansies Are the Predominant Plants Offered for Seasonal Color
A Horticulture Information article from the Wisconsin Master Gardener website, posted 3 Sept 2007 Ornamental Cabbage and Kale, Brassica oleracea In the fall, chyrsanthemums and pansies are the predominant plants offered for seasonal color. But another group of cold-tolerant plants without fl owers can help brighten the fall garden when almost ev- erything else is looking tired and ready for winter. Ornamental cabbage and kale are the same species as edible cabbages, broccoli, and caulifl ower (Bras- sica oleracea) but have much fancier and more col- orful foliage than their cousins from the vegetable garden. While these plants are sometimes offered as “fl owering” cabbage and kale, they are grown for their large rosettes of colorful leaves, not the fl owers. These plants are very showy and come in a variety of colors, ranging from white to pinks, purples or reds. Even though they are technically all kales (kale does not produce a head; instead, it produces leaves in a tight rosette), by convention those types with deeply- cut, curly, frilly or ruffl ed leaves are called ornamen- Ornamental kale makes a dramatic massed planting. tal kale, while the ones with broad, fl at leaves often edged in a contrasting color are called ornamental cabbage. The plants grow about a foot wide and 15” tall. Ornamental cabbages and kales do not tolerate summer heat, and plants set out in spring will likely have bolted or declined in appearance, so it is necessary to either start from seed in mid-summer or purchase trans- plants for a good fall show. -

How to Grow Cabbage (Brassica Oleracea) Cabbage Varieties Come in a Spectrum of Colors, from Light Green to Dark Purple
How to Grow Cabbage (Brassica oleracea) Cabbage varieties come in a spectrum of colors, from light green to dark purple. The scientific name of cabbage is Brassica oleracea, a species that also includes broccoli, cauliflower, kale, and Brussels sprouts. Time of Planting: Sow cabbage seeds indoors 4-6 weeks before transplanting seedlings outdoors. Transplant cabbage seedlings outdoors just before the last frost. Spacing Requirements: Sow seeds ¼ inch deep. Space cabbages at least 24-36 inches apart in even spacing or 12-14 inches apart in rows spaced 36-44 inches apart. Time to Germination: 7-12 days. Special Considerations: When growing for seed, increase spacing to 18-24 inches apart in rows that are at least 36 inches apart. Staking is recommended. Common Pests and Diseases (and how to manage): Cabbage can suffer from a number of pests and diseases including flea beetles, cabbage moths, aphids, leaf miner bugs, slugs, and black rot. Early season insect pests, such as flea beetles, can be deterred by growing transplants underneath row cover. Harvest (when and how): Cut the head at the base of the plant with a harvesting knife or pruning shears as soon as the cabbage head feels solid. Trim off the loose outer leaves and store heads in a cool place. Eating: Raw cabbage can be used in fresh salads like coleslaw. It can also be enjoyed roasted, braised, stewed, and stir fried. Cabbage is often fermented to make sauerkraut and kimchi. Storing: Cabbage will keep for about four months at a temperature between 32-40 degrees F and a relative humidity of 80-90%. -
