Genetic Variability in Bangladeshi Aromatic Rice through RAPD Analysis Full text
2014
Mehfuz Hasan | Mohammad Sharif Raihan
Genetic polymorphism and relationships among 30 commercial varieties of Bangladeshi aromatic rice (Oryza sativa L.) were established using random amplified polymorphic DNA (RAPD) primers. Out of fifty 10-mer RAPD primers screened initially, four were chosen and used in a comparative analysis of different varieties of indigenous Bangladeshi aromatic rice. Of the 33 total RAPD fragments amplified, 7 (21.21%) were found to be shared by individuals of all eight varieties. The remaining 26 fragments were found to be polymorphic (78.79%). Pair-wise estimates of similarity ranged from 0.101 to 0.911. Highest genetic diversity was determined between Radhunipagol and Dubsail varieties (0.911). The amount of genetic diversity within aromatic rice germplasm was quite high as determined by the genetic similarity coefficients between varieties. Genetic similarities obtained from RAPD data were also used to create a cluster diagram. Cluster analysis using an un-weighted pair-group method with arithmetic averages (UPGMA) was used to group the varieties and the 30 aromatic rice varieties were grouped into 6 clusters where cluster I includes the maximum number of varieties (9). Cluster VI includes minimum number of varieties (2). This Study offered a rapid and reliable method for the estimation of variability between different varieties which could be utilized by the breeders for further improvement of the local aromatic rice varieties.

In this study, Minneola Tangelo hybrid, a cross of grapefruit and mandarin (Duncan grapefruit x Dancy mandarin), used as interstock to Star Ruby grapefruit with different lengths. Effects of different interstock lengths on fruit yield and quality, plant development and photosynthetic parameters were investigated. According to the results, different interstock lengths significantly affected fruit yield and size. The highest fruit yield was determined in T-M20-S whereas the lowest was on T-M5-S. The highest fruit size were determined in Star Ruby fruits on T-M5-S and T-M40-S whereas the lowest on T-M20-S and T-S (control). T-M40-S and T-M20-S treatments markedly reduced stem diameter and tree canopy in comparison to other treatments and control. Usage of different interstock lengths did not significantly affected some of fruit quality traits, net photosynthetic rate, stomatal conductance, leaf transpiration rate, leaf water usage efficiency and leaf chlorophyll concentration. In regards to seasonal changes, net photosynthetic rate were higher in spring and summer seasons then winter and fall seasons.

Hari Shankar Yadava
Twenty five land races from Madhya Pradesh and ten germplasm of coriander were evaluated in four environments to assess umbel per plant using multivariate analysis. Mean sum of squares due to genotypes, environments and GEI were highly significant for umbels per plant. Variation in GEI was mainly due to heterogeneity. ). PCA 1 and PCA 2 captures the 99.42% of interaction sum of squares hence, these two principal component axes were the best predictive. The potential environment the potential environments E3 (high fertility, 2009-10) bearing lowest interaction effect while, least potential environments E2 (low fertility, 2008-09) exhibited high PCA scores. The biplot of genotype, environment and IPCA 1 showed three groups. One group exhibited the similar main effects (mean umbels per plant) to the grand mean. The second group showed high interaction effect varied in direction while third group bear the low interaction effect. AMMI Stability Values (ASV), ranging from from 7.444 to 31.099 was lowest in RVC 8 followed by RVC 4, RVC 11, RVC 21, RVC 9 and RVC 3 whereas, it was noted maximum in RVC 19 followed by Moroccan, CS 193, Simpo S 33 and G 5363. The genotypes exhibiting low IPCA scores and ASV namely, RVC 8, RVC 4, RVC 11, RVC 21, RVC 19 and RVC 25 showed wider adaptability for umbels per plant while, RVC 19, Moroccan, CS 193, Simpo S 33 and G 5363 exhibiting specific adaptability towards environmental conditions. These genotypes can be utilized in breeding programmes to transfer the adaptability genes for umbel per plant into high yielding genetic back ground in coriander.

The aim of this study was to assess the effect of heat treatment and salt concentrations (0, 5, and 10%) on the free amino acids (FAA) composition of Sudanese braided cheese (BC) ripened for up to 3 months at 5±2°C. Heat and salt concentration significantly affected the FAA of braided cheese. The free amino acids concentrations of BC ripened in 0%, 5%, and 10% salted whey (SW) were significantly fluctuated. Under ripening conditions tested (salt level + time), braided cheese made from pasteurized milk (BCPM) had consistently lower values of FAA than braided cheese made from raw milk (BCRM). In fresh cheese, the major FAA in BCRM were Glu (36.12 nmol/ml), Leu (26.77nmol/ml) and Lys (14.51 nmol/ml) while the major ones in BCPM were Lys (2.94 nmol/ml) and Ala (2.45 nmol/ml). BCPM stored in 10% SW had shorter quality life compared to that stored in 5% salted whey.

Ralstonia solanacearum is a very destructive bacterial plant pathogen that causes wilt disease in solanaceae crops. To study the response of potato, tomato, eggplant and petunia to bacterial wilt disease, two isolates representing biovars 2A and 2T of R. solanacearum were evaluated for their pathogenicity aggressiveness and tobacco hypersensitivity response (HR) at two different temperature regimes. The response of plants was estimated by appearance of wilting symptoms and bacterial density in the xylems of inoculated plants over a four weeks period. The results indicated that isolates representing biovar 2T caused less disease in all the species and cultivars compared to isolates biovar 2A, at both temperature conditions and also, there were significant differences in susceptibility to biovars 2A and 2T of R. solanacearum among tomato, eggplant and petunia and potato cultivars.

Uniform description of developmental stages in crops improve communication among producers, researchers and others. A standardized, accurate, and easy system is needed to describe bean (Phaseolus vulgaris L.) plant development. The objective of this study was to develop and describe stages of bean plant development in a manner which is simple but accurate. The biological cycle of the bean plant is divided into two successive phases: the vegetative stage (V) and the reproductive stage (R). Vegetative stages are determined by counting the number of trifoliolate leaves (V1 to VN) on the main stem beginning above the unifoliate leaf. Reproductive stages R1 and R2 are based on flowering, R3 and R4 on pod development, R5 and R6 on seed development, and R7, R8 and R9 on maturation.
