Validation Of Newly Designed Ssr Markers For Eight Rice (Oryza Sativa L.) Genotypes With Variable Heat Tolerance Responses Based On Agromorphic Data And Pollen Fertility Analysis [Research Note], Monaliza B. Magat, Norvie L. Manigbas, Jessica D. Rey

The Philippine Agricultural Scientist

Rice is one of the most valuable staple food crops in the world. However, several challenges greatly affect production, one of which is the threat imposed by heat stress. To address this, researchers are developing varieties that are heat stress tolerant with genetic markers aid. In this study, eight rice genotypes, namely Dular, Nagina 22, NSIC Rc 222, Milyang 23, EL15, EL92, EL85, and IR52 were observed for agromorphic data, which included plant height, panicle length, filled and unfilled grains, and grain yield. Flower samples were collected to determine the effect of heat stress on pollen fertility. Molecular markers were …

Epinasty Accompanies Potassium Nitrate-Induced Flower Bud Break In 'Carabao' Mango [Research Note], Ulysses Besas, Calixto Protacio

The Philippine Agricultural Scientist

The hypothesis that potassium nitrate application promotes epinasty in ‘Carabao’ mango through increased ethylene production was investigated. The degree of drooping, apical primordium growth as affected by shoot ethylene and levels after potassium nitrate spraying were monitored. Evidence presented established for the first time in ‘Carabao’ mango that epinasty occurred just before flower emergence, coinciding with visible bud break, and extended up to 18 days, marking floral anthesis. The possible reasons could be the higher levels of ethylene at 0.31% and earlier increase of ethylene in the shoot apex at four hours and apical primordium growth. Increased ethylene levels at …

Estimation Of Genetic Diversity Among Canola Accessions Using Simple Sequence Repeat Markers, Jaleel Ahmad, Muhammad Baber, Wajid Nazeer, Sana Hamdullah, Aleena Ahmad Somroo, Shaiza Ali, Rameen Fatima, Seema Aslam

Journal of Bioresource Management

Genetic studies through molecular markers proved important to find out the genetic diversity of canola. In this study, 50 lines of canola were used to find the polymorphism using 15 SSR primers and investigated the genetic diversity, PIC values, frequency-based genetic distance, and allelic frequencies. Mean gene diversity, frequency-based genetic distance, and PIC values were 0.8777, 0.233 and 0.8666, respectively for the canola lines. A good range of genetic diversity was found among studied canola lines with value 85.91% polymorphism. Maximum and minimum genetic distances among 50 lines were 1 and 0.26, respectively. Accessions ACC-26068, ACC-24241, ACC-24244, ACC-24233, ACC-24423 and …

Genetic Diversity And Population Structure Of Sugarcane (Saccharum Officinarum L.) Collected From Seven Philippine Regions For Use As Breeding Stocks For Crop Improvement, Jan Leandro Acedera, Jhun Laurence Rasco, Jemimah Banganan, Antonio Lalusin

The Philippine Agricultural Scientist

Selection of parents for hybridization relies on the information on their genetic relationship and diversity which are essential in any breeding program. This study aimed to estimate the extent of genetic diversity and population structure of 76 sugarcane accessions from seven regions in the Philippines using 57 morphological characters and 50 microsatellite markers. The sugarcane collections exhibited moderate to high diversity with mean of H’ = 0.72 for qualitative and H’ = 0.75 for quantitative morphological characters, respectively. This is corroborated by the analysis of variance (ANOVA) of agronomic parameters, except for stalk length. Unweighted Pair Group Method with Arithmetic …

Recognizing Challenges And Opportunities In The Quest To End Hunger, Jennifer Williams Zwagerman

Texas A&M Law Review

As an attorney and professor that does not focus on intellectual property law, I was a bit apprehensive about providing a keynote address for a Symposium focusing on “Agriculture, Intellectual Property, and Feeding the World in the 21st Century.” As I thought about this topic, knowing that there were other speakers who would focus more on the IP issues and technical aspects of various topics, I kept coming back to the importance of technology as we worktowards the goal of feeding the world, and the many ways in which innovation plays a role in meeting that goal. It also brought …

A Novel Gene Silencing Vector For Plant Genomics And Biotechnology, Dustin Hoover, Scott Nicholson, Vibha Srivastava

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Gene silencing is a process of suppressing activity of specific genes by producing “interfering” RNA encoded by foreign genes. This process serves as the principle of genetic modification in plants and animals, which is an important tool in genomics and biotechnology, allowing scientists to manipulate organisms to better meet human demands. New approaches of gene silencing may enable improvements on current practices of genetic modification, and broaden the application and impact of gene silencing in biotechnology. Recently, a novel vector design consisting of the transcription of short gene fragments lacking transcription termination signals was demonstrated to be effective in partial …

The Awassi Fat Tail Sheep Project, R J. Lightfoot

Journal of the Department of Agriculture, Western Australia, Series 4

Australia's first Awassi fat tail lambs arrived at Kununurra in January 1987, completing the first major step in an ambitious project to establish a fat tail sheep breeding industry in this country.

Fat tail sheep bred in the Middle East attract much higher prices than merino wethers imported from Australia. The question to be resolved through our product development and market research is what premiums will Middle Eastern buyers pay for fat tail sheep bred in Australia and exported to the region.

The Department of Agriculture believes that there is potential for Sustralian producers to enter these new markets without …

Special Field Days For Merino Breeders, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

More than 200 Merino stud breeders attended special stud breeding and fertility field days arranged for them by the Department of Agriculture recently.

Breeders attending represented some 40 per cent of the State's Merino studs.

Twinning Increases Production, K P. Croker

Journal of the Department of Agriculture, Western Australia, Series 4

Many breeders claim that twinning causes too many losses among Merino lambs and does not favour breeding for twin lamb production.

But recent experiments have proved otherwise and agricultural scientists now agree that . . .

TWINNING INCREASES PRODUCTION

THE low marking percentages regularly recorded for Merino flocks suggest that the Merino is a relatively infertile breed.

Certainly, lambing percentages are low when compared with those of most British breeds of sheep.
