We examined reproductive isolating barriers at four postmating stages among 11 species from the morphologically diverse genus Nolana (Solanaceae). At least one stage was positively correlated with both genetic and geographic distance between species. Postzygotic isolation generally stronger faster evolving than prezygotic isolation. In addition, there no evidence for mechanical isolation, or character displacement in floral traits that can influence pollinator general, potential here,...
We screened 429 individuals from 31 diploid Ipomoea trifida accessions different countries of Central and South America for 2n pollen production. Almost 20% this population was found to produce in frequencies. The production is not an isolated incident but a common phenomenon taxon. Pollen diameter measured normal pollen-producing clones. 30% larger than that pollen, making it very easy detect producers measure their frequency. Production confirmed by the finding dyads triads anther samples...
Dry matter content in potato ( Solanum tuberosum L.) is an important factor processing and estimated by specific gravity. We performed quantitative trait loci (QTL) analysis for this 2 x three environments. A population of 110 individuals was derived from the cross a hybrid haploid S. (2 ) chacoense Bitter, with phureja Juz. & Buk. clone. This characterized 10 isozyme loci, 44 restriction fragment length polymorphisms (RFLPs), 63 random amplified polymorphic DNA (RAPDs). Field trials...
To conduct and evaluate a two-phased community-based approach to recruit lower socioeconomic status, minority, or Spanish-speaking adults at risk of developing diabetes randomized trial lifestyle intervention program delivered by public health department.
Twenty-two synthetic hexaploids and 33 triploids with 2n pollen production of Ipomoea trifida were used in crosses to estimate their male female fertility crossability sweet potato, batatas (L.) Lam. Several important conclusions drawn. (i) The the triploid plants was confirmed, which suggested they are truly functional pollen. (ii) average hexaploid higher than that plants. (iii) egg observed several genotypes, (iv) From a polycross, 3079 seeds normal shapes produced. These represent...
The genetics and anthocyanins responsible for flower color were studied in Ruellia simplex Wright (mexican petunia). An F 2 population with 153 individuals segregating four colors was developed from a cross between maternal individual white corolla purple throat (WP) paternal pink (PK). All the 1 generation had fully flowers (P). segregated 94 P:30 PK:24 WP:5 WPK (WPK is new combination of limb throat). These data separated into groups color. ratio PK:29 W, which fits 9:3:4 recessive...
Crosses were made between 21 tetraploid accessions and 41 diploid of Ipomoea trifida, obtaining a total 9185 triploid seeds from 215 different cross combinations. Doubling the somatic chromosome number triploids was attempted by colchicine treatment on young seedlings to obtain synthetic hexaploids. A 787 axillary buds 316 plants treated with 0.5% solution for 24 h, applied cotton plugs surrounding buds. The survival rate was, average, 41%. ploidy level in germ-layer L 2 determined 258...
The objectives were to 1) compare growth and yield of different ginger ( Zingiber officinale ) turmeric Curcuma longa propagules grown under two photoperiods (Expt. 1); 2) evaluate whether their growing season could be extended with night interruption lighting (NI) during the winter 2). In Expt. 1, included micropropagated tissue culture (TC) transplants, second-generation rhizomes harvested from TC transplants (2GR), 3) seed (R). Plants received natural short days (SDs) or NI providing a...
Plants of Anagallis monelli in their native habitat or cultivation have either blue orange flowers. Clonally propagated cultivars, seed obtained from commercial sources and the resulting plants were grown a greenhouse at University New Hampshire. F 2 progeny hybridization between blue- orange-flowered had blue, red There no significant differences petal pH orange-, blue-, red-flowered that could explain flower color. Anthocyanidins characterized by high-performance liquid chromatography....
Mexican petunia ( Ruellia simplex Wright) is a non-native plant that was introduced to Florida sometime in the 1940s and since then has naturalized most of state other southern states. Since 2007, we have developed at University Florida/Institute for Food Agricultural Science Gainesville first L. breeding program aiming develop fruitless plants with different flower colors growth habits will not be invasive by seed dispersal. A combination polyploidization hybridization methods used. In...
Reciprocal crosses, both intraspecific and interspecific, were made among five Chilean species of Nolana (Solanaceae), a genus native to western South America. With the exception N. paradoxa , plants all used grown from mericarps collected wild populations. Self-pollinations generally not successful, suggesting obligate allogamy. A total 333 hybridizations performed, which 109 224 interspecific. Successful hybridizations, as measured by formation fruits, produced for acuminata (83%), elegans...
