Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2016 in the subject Biology - Genetics / Gene Technology, Mar Augusthinose College, language: English, abstract: Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. Jack fruit has diverse medicinal uses, especially anti-oxidant, anti-inflammatory, anti-microbial, anti-cancer and anti-fungal activity. Jackfruit is considered to be an underutilized fruit where most of the fruits get wasted due to ignorance, lack of post harvest technology and gaps in supply chain systems.Jackfruit contains more protein, calcium, iron, vitamins and other essential nutrients as compared to the common fruits. To find out the morphological variation among jack fruits among Kerala we conducted an elaborative survey and found out the parameters such as tree characteristics, leaf characterises or fruit characteristics of selected samples.Both qualitative and quantitative data are measured using field visits and standard methods and morphological indicators; after analysis of data there is a morphological variation among the jack fruit samples identified. Advances in the genetic markers such as RFLP and PCR based methods are more reliable for identification of genetic diversity than morphological markers although each technique has advantages and limitations.The objective of this research work was to estimate the level of genetic diversity and to assess genetic relationships among six varieties of jackfruit using the 'rbcL gene' based on PCR technique and RFLP markers. The partial sequence of 'rbcL' gene of six different Artocarpus varieties was used in the analysis. The size of amplified products was approximately 700 bp. After sequencing and sequence editing, sequence information on a 651 bp region was finally obtained for analysis. The alignment of sequences revealed two haplotypes out of 651 sites. The nucleotide frequencies are 27.96% (A), 29.47% (T/U), 19.69% (C), and 22.89% (G). Being one of the underutilized fruits in India, Artocarpus heterophyllus Lam has promising leads to further scientific research and livelihood strategies. The study of rbcL gene using PCR and RFLP seems to be a promising tool in establishing genetic diversity among jackfruit varieties.…

Etat : Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | The present investigation ¿Morphological Characterization based Genetic Diversity in Chickpeä was undertaken in 40 genotypes. The number of pods per plant exhibited highest range of variability followed by days to 50 per cent flowering, height of the plant and 100 seed weight. The estimates of genotypic as well as phenotypic coefficient of variation were highest for seed yield per plant followed by number of pods per plant, 100 seed weight and number of secondary branches. The highest heritability was observed for 100 seed weight followed by seed yield per plant, number of pods per plant and days to 50 per cent flowering. The seed yield per plant showed highly significant and positive correlation with number of pods per plant, 100 seed weight, and height of the plant. The character 100 seed weight was the maximum contributor towards divergence followed by number of pods per plant, days to 50 per cent flowering and seed yield per plant. On the basis of inter cluster distances, cluster means and per se performance, the five genotypes viz., IC-83429, Vishal, IC-83397, IC-83340 and IC-83523 were found to be superior genotypes for further breeding programme.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Present manuscript describes the genetic characterization of endangered sheep breed called Kutta. Kutta sheep is a native breed of Swat Valley of Khyber Pakhtun khwa of Pakistan. The sheep is black coated small sized thin tail breed. Males are horned and female are polled. Utilization of the breed is limited to wool production and for manufacturing hand woven cloth; locally called 'Lamsay & sharri'. Its population is at extremely alarming position. The estimated population of Kutta breed in 2007 is less than 1000 and can be classified as endangered species. The prime reason of its decrease in population is its extensive out cross with other exotic breed of sheep like Rambouillet, Balkhi etc. As nearly 20% of the documented breeds are considered to be under the threat of extinction so far of 7600 breeds documented in the databank animal Genetic Resources (AnGr) 11% got extinct and only 38% are safe from extinction. Surprisingly approx. 35% is still not yet properly known and before it's properly documentation going on, its extinction might happen. Kutta is also among those breed which is going to extinct. A list of FAO recommended SSR markers were used to tract the genetic diversity.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Plant biotechnologist frequently have to analyze the genotype of multiple polymorphic loci. For multi-sample or multilocus genotyping, many researchers employ labor-intensive methods, such as cleaved amplified polymorphic sequences, restriction fragment length polymorphisms and simple sequence repeats (SSR). To develop races for a particular constraint of plant production, genotypes are very beneficial to plant breeders and application of modern tools like DNA markers such as SSR to these genotypes will help for further insight into rice genome and to develop rice with more resistance to the biotic and abiotic constraints of modern ecosystem. Hence the present investigation on molecular characterization of genotypes will strengthen the germplasm units for their better usage which in turn would affect the yielding ability of plant. The importance of having a large set of SSR markers is to provide a bridge for moving rapidly and efficiently from phenotype to sequence information and vice-versa, and providing a foundation for understanding the evolutionary consequences of sequence variation.…

The indegenious germplams of Brassica Campestris was improved through modern molecular and conventional breeding techniques. In conventional breeding the Brassica campestris cultivars were crossed with Brassica napus varieties and the offsprings were then evaulated for genetic diversity through molecular (RAPD and SSR) markers. …

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Indigenous sheep genetic resources are not only vital for their economic and cultural value but also for their scientific value since they harbour unique genetic variants which confer traits enabling them to survive in harsh environments with very minimal input if any. Unfortunately such genetic resources are threatened with extinction due to the indiscriminate crossbreeding with their exotic counterparts that seem more productive but require a lot more economic investment. Instituting conservation efforts for indigenous sheep is really overdue but this can only be done after their distribution is appreciated through characterization both at the molecular as well as phenotypic level.…
