Coffee is one of the most important plantation crops, grown in about 80 countries across world. The genus Coffea comprises approximately 100 species which only two species, that is, arabica (commonly known as coffee) and canephora (known robusta coffee), are commercially cultivated. Genetic improvement coffee through traditional breeding slow due to perennial nature plant. transformation has tremendous potential developing improved varieties with desired agronomic traits, otherwise difficult...
Stomatal frequency, epidermal cell stomatal guard length and index were examined at different ploidy levels in Coffea . In general, frequency per unit leaf area decreased while increased with an increase ploidy. The reduction higher was mainly a result of larger cells. the case C. canephora (cultivar S.274) significant noticed from diploid to tetraploid level which due both size less differentiation level. Besides effect on length, genotypic differences also observed among cultivars same...
Coffea canephora Pierre ex Frohener is popularly known as robusta coffee contributes to about 39% of the total world production. a native West Africa was introduced India early 1900 AD. However adequate information regarding diversity and genetic structure C. germplasm available in not yet available. In present study, sequence related amplified polymorphism (SRAP) start codon targeted (SCoT) molecular markers were employed access relationships 58 accessions Indian gene bank. Forty-nine SRAP...
Coffea arabica L. is the only cultivated tetraploid species in genus and it contributes more than 61% to total world coffee production. Arabica produces superior beverage quality compared robusta but susceptible a number of pests diseases. Improved varieties coupled with durable disease resistance can be achieved by incorporating novel sources genetic variation from diverse germplasm sources. Assessment diversity within pool prerequisite for estimating its true breeding potential. In present...
The identification and genetic relationships of 23 coffee species one coffee-related Canthium diccocum were studied using ISSR SRAP markers. average polymorphism information content primers (0.81) was lower than (0.86), whereas the resolving power (9.74) is higher (8.64). similarity among ranged from 0.30 to 0.89 0.11 0.90 marker systems. Based on analysis, all twenty three clustered into two major groups. Both markers amplified species-specific fragments are useful in diversity analysis coffee.
Information on genetic diversity of different commercial coffee cultivars grown in India during the last 90 years is scarce. In present study, selected cultivars, along with some advanced breeding lines, was evaluated using random amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), and sequence-related polymorphism (SRAP) markers. The average information content (PIC) or ISSR primers (0.365) higher than that for both RAPD (0.222) SRAP (0.346). resolving power (Rp) (13.29)...
Abstract This study was conducted to compare the growth and yield of one commercial hybrid coffee cultivars ( Coffea congensis x canephora ) robusta established from somatic embryogenesis as well conventional seedlings. Results indicated no statistically significant differences in pattern or cumulative between derived plants The genetic fidelity mother plant tested using sequence related amplified polymorphism (SRAP) markers. A total 24 SRAP primers were employed for DNA analysis which...
Abstract The South-Western highlands of Ethiopia are considered to be the centre origin and diversity arabica coffee, Coffea . More than 80 accessions coffee collected from available in Indian gene bank. However, genetic these is not studied detail. In present study, analysis 48 eight provinces was carried out using Sequence-related amplified Polymorphism (SRAP) marker. Among thirty two SRAP primer combinations tested, 14 pairs were polymorphic generated 203 distinct fragments. number...
The green fluorescent protein (GFP) was used as a visual selectable marker to produce transgenic coffee (Coffea canephora) plants following Agrobacterium-mediated transformation. binary vector pBECKS 2000.7 containing synthetic gene for GFP (sgfp) S65T and the hygromycin phosphotransferase hph both controlled by 35S cauliflower mosaic virus CaMV35S promoters Embryogenic cultures were initiated from hypocotyls cotyledon leaves of in vitro grown seedlings target material. Selection transformed...
Abstract Coffee leaf rust caused by the fungus Hemileia vastatrix (Berk and Br.) is a major disease occurring in coffee plantations. Although exists different physiological races, genetic difference between them meagrely understood. In this study, diversity of 14 identified two unidentified races was determined sequence‐related amplified polymorphism ( SRAP ) markers. Of 48 primer pairs tested, 35 primers are polymorphic generated 347 distinct scorable fragments. The number fragments ranged...
Studies were conducted in the Dept. of Plant Pathology Odisha University Agriculture and Technology, Bhubaneswar for various physiological requirements Sarocladium oryzae causing sheath rot rice. It was revealed that Potato dextrose agar supported significantly maximum radial growth (74.0mm) followed by Sabouraud’s medium (71.8mm) Czapek’s dox (70.0mm). Significantly dry weight mycelial mat at pH 4.0 (769.0mg) 3.5 (746.6 mg). The highest observed 12 hour light darkness (68.1mm) closely 8 16...
