The spontaneous emergence among common pea (Pisum sativum L.) cultivars of off-type rogue plants exhibiting leaves with narrower and pointed leaflets and stipules and the non-Mend. Background. A development funiculus (def) mutant pea (Pisum sativum) is known as a spontaneous mutation with monogenic recessive inheritance .The chromosomal location of the Def allele has been found to be located at the bottom end of linkage group VII corresponding to chromosome no 4 .Usually in wild type pea, there is a distinctive cell separation between funicle and seed coat that Cited by: 4. The genetic diversity among 28 pea (Pisum sativum L.) genotypes was analyzed using 32 simple sequence repeat markers. A total of 44 polymorphic bands, with an average of bands per primer, were obtained. The polymorphism information content ranged from to with an average of The variation in genetic diversity among these cultivars ranged from to Summary: Together with an outstanding practical value, garden pea (Pisum sativum L.) represents a classical model object for studies on ontogeny of compound inflorescence, compound leaf, induced artificially or discovered in cultivated that during more than years of genetic studies.
Field pea (Pisum sativum L.) is an important protein-rich pulse crop produced sing the lipid content of Pisum seeds through conventional and contemporary molecular breeding tools may bring added value to the crop. However, knowledge about genetic diversity and lipid content in field pea is limited. An understanding of genetic diversity and population structure in diverse. The systematic characterization of gene functions in species recalcitrant to Agrobacterium-based transformation, like Pisum sativum, remains a challenge. To develop a high throughput forward and reverse genetics tool in pea, we have constructed a reference ethylmethane sulfonate mutant population and developed a database, UTILLdb, that contains phenotypic as well as . Genetic variability correlation and path analysis studies in garden pea (Pisum sativum L.) Journal of Agricultural Resea Qasim M, Zubair M, Wadan D. Evaluation of exotic cultivars of pea in Swat valley. Pisum sativum possesses many advantages as a study material in the hybridization experiment that knowingly or unknowingly helped Mendel to derive a logical conclusion from his crossing experiments. The advantages of Pisum sativum as a study material in hybridization experiments are given below. Ø Pisum sativum is an annual plant with a short span of life cycle.
The purpose of this study was also to evaluate the genetic diversity within a diverse collection of pea (Pisum sativum) accessions. The RAPD technique has advantages over isozyme and other DNA fingerprinting technologies in the speed of data- acquisition possible, the low cost of reactions, the small amounts of plant material required and the. The spontaneous emergence among common pea (Pisum sativum L.) cultivars of off-type rogue plants exhibiting leaves with narrower and pointed leaflets and stipules and the non-Mendelian inheritance of this new phenotype were first described in the early 20th century. However, so far, no studies at the molecular level of this first identified case of paramutation have been carried out. Variation in cell population size and cell weight in the cotyledons are important factors in determining seed weight in Pisum sativum. The regulation of these parameters as well as that of growth rate has been examined. The use of reciprocal crosses between varieties of contrasting seed size has allowed the recognition of two systems of control—an intrinsic one dependent on the seed's own. estimate genetic variability, heritability and genetic advance in the available germplasm of field pea (Pisum sativum L.). A quantitative measure which provides information about the correspondence between genotypic variance is heritability. 2. Material and Methods. The experimental material for the present investigation.
