Molecular diversity assessment using ssr primers confirming distinct species of jute germplasm under Corchorus genus

ABSTRACT

The aim of the experiment was to find out genetic diversity of some jute germplasm collected from different locations of the world that are stored at the gene bank of Bangladesh Jute Research Institute (BJRI). The experiment was conducted at the laboratory of Cytogenetics department of Genetic Resources and Seed Division of BJRI. Genetic variation among 22 jute germplasm including 9 varieties of BJRI were determined using 33 SSR primers. DNA was extracted from seedlings following mini preparation CTAB method with some modifications. Vertical gel electrophoresis system was used with polyacrylamide gel. Among these,   14 primers were polymorphic and amplified 39 loci. The highest gene diversity value among the polymorphic primers was 0.685 and the lowest was 0.177 with an average of 0.507. The highest genetic distance value (1.0) was found between Corchorus capsularis (white jute) and C. olitorius (dark jute/tossa jute) germplasm. Among the C. olitorius germplasm, the highest genetic distance value (0.4) was found between accession no. 1039 and accession no. 1347. Among the C. capsularis germplasm, accession no. 4484 showed the highest genetic distance value (0.214) with varieties CVL-1 and BJRI Deshi Pat Shak-1. UPGMA dendrogram, based on genetic differences separated the germplasm of two different species in two main clusters and the cluster of C. olitorius is subdivided into two sub-clusters. We found no genetic similarity between the two species of jute. Plant breeders can consider the studied germplasm of C. olitorius as more potential for crossing programs as they have good genetic diversity.

SURVEY ON ARTHROPOD PEST OF CAPSICUM AND DIFFERENT PRACTICES USED BY THE CAPSICUM GROWERS AGAINST INFESTATION IN MAJOR GROWING AREAS OF BANGLADESH

ABSTRACT

The study was conducted at Rajbari, Manikganj, Bogura, Sylhet and Kishoreganj district to study on farmers’ practices for the management of capsicum insect pest in major capsicum growing areas of Bangladesh. Data were collected by the researcher during the period from 15 October to 15 November 2018. Among the respondent the maximum (87.2%) capsicum growers were cultivated capsicum in winter season and 12.8% capsicum growers were cultivated in summer season. The highest around 36.00% have low level infestation whereas only 4.80% were belongs to severe level insect pests’ infestation under the study area. Capsicum growers practices (CGPs) related data were collected at two levels: directly from the sample farmers by administering pre-designed and pre-tested questionnaires. Total 11 capsicum varieties were recorded from the study area and the highest used capsicum varieties California wonder (17.21%), Omax hybrid (15.35%), BARI misti morich -2 (13.84%). BARI misti morich-1 (12.36%), Bell pepper (9.1/0%) and Marcuri rosso (7.23%). Total 10 insect pests of capsicum were recorded from the study area. Among the insect pests capsicum fruit borer and aphid were dominant and observed upto 100% respondent farmer’s field. The capsicum growers practices (CGPs) for capsicum insect pest management were generally three broad types. Type I Non-chemical, bio-pesticide and untreated control practices; Type II was combination of chemicals with other management practices and Type III was combination of non-chemicals management practices comprising bio-pesticide, mechanical, cultural and mulching materials. Most of the respondents of capsicum growers (71.14%) practiced Type II, whereas, Type I was practiced by  23.08% and Type III was practiced by only 5.77% of respondents of capsicum growers of the respective districts. The BCR was maximum in CGP 8, CGP 9, CGP11, CGP 12 and CGP 10 (3.12-2.90) while it was minimum (2.06-2.15) in CGP 7 and CGP 15. Application of integrated pest control measures were more effective compared to single control measure for capsicum cultivation regarding insect pest management.

General evaluation of two success stories of M. A. MIYAN on IUBAT and KBAD

ABSTRACT

Prof. Dr. M.A. Miyan established IUBAT with wide success where he developed two concepts regarding IUBAT and KBAD and published those materials in two reports and referred in the references. On the basis/guideline of the reports, concepts, mission, vision and philosophy of IUBAT and KBAD are developed for future generations. Fig. 1. showed the KBAD’s summary as mission and vision.

Key words: P IUBAT, KBAD, concepts, mission, vision, philosophy.

BACKGROUND, MISSION, VISION AND OPERATIONAL PHILOSOPHY OF IUBAT

IUBAT-International University of Business Agriculture and Technology is the first Nongovernment university in Bangladesh. Prof. Dr. M. Alimullah Miyan was the founder of IUBAT as well as the pioneer regarding the building/development of private university in Bangladesh.In 1980s there were only six universities like Dhaka University, Rajshahi University, Chittagong University, Jahangirnagar University, BAU and BUET where admission capacity covered only 10000-12000 students although there were several lakh good students (better SSC and HSC results) failed to proceed for higher studies. Then thousands of students moved to India and that was the great business for many universities of India. It was really bad days regarding higher education in Bangladesh. Prof. Dr. Alimullah Miyan, Director of the Institute of Business Administration (IBA), Dhaka University with wide depth of national and international latest knowledge, observed the university education crisis of the children came forward with private university concepts. With World Bank sponsor, he visited Kansas State University (KSU), Manhattan, Kansas, USA for 3 weeks where he faced a lot of discussions with 40 Academicians regarding role of universities of USA relevant to society and tried to discover the application of such role of university to the society in Bangladesh. Dr. M.A. Miyan is basically rich is Business Administration and KSU is rich in Agriculture. Moreover, for food security, agriculture is important for Bangladesh. So, Dr Miyan finally took two major issues covering business and agriculture in his concepts, mission and vision and then developed a proposal on “Proposal for establishing a university of business, agriculture and technology at Dhaka, Bangladesh with academic collaboration and recognition of Kansas State University” on April 3, 1989 under his guideline on “Non-government University movement in Bangladesh”. The proposal widely and excellently covered under proper headlines like Introduction, Background, Objectives, Scope of the university, Organization, Resources, Conclusions and a Structure of the University (model). His presentation and discussions with KSU Academician’s were widely fruitful and successful and finally KSU authority came forward to help him in all aspects of academic matters and gave him a letter by Verman C. Harson on April 27, 1989 covering “letter of intent to participate in a new university in Bangladesh”. That was the great success of Dr. Miyan to develop a University of Business Agriculture (UBA) in Bangladesh.

Comparative yield performance study of some mustard mutants at medium highland in Mymensingh region

ABSTRACT

The present research was conducted at the farmer’s field of Sadar, Mymensingh during Rabi season 2016-17 to investigate the growth and yield performance of mustard mutants. The experiment was arranged in a randomized complete block design consisting of two mustard mutants (viz. RM-07, RM-10 and BARI Sarisha-15) as treatment and replicated thrice. All the growth, yield attributes and yield were substantially influence among the mustard mutants except the phenological parameters. Results of the experiment showed that the highest plant height in RM-07 (100.93 cm), seed yield in RM-10 (1.76 tha-1). RM-10 was found better in respect of maximum siliqua plant-1, 1000-seed weight in RM-07. Besides this, RM-07 showed the maximum number of seeds siliqua-1. Therefore, findings of this study suggested that RM-10 would be suitable for better productivity and recommended for cultivation in the medium highland at Mymensingh region in Bangladesh.

Effect of salinity stress on the growth and yield of wheat genotypes

ABSTRACT

A pot experiment regarding salinity tolerance of wheat was conducted at the pot yard of Bangladesh Institute of Nuclear Argiculture (BINA), Mymensingh during the period from November to March 2017. Three wheat    genotypes namely Sonalika, Ananda and GPB-110 were used to observe the relative salinity tolerance under different treatments. Salinity treatments showed significant effect on the growth and yield of wheat. Plant height, number of grain per spike, length of spike, grain yield per plant, 1000-grain weight and straw yield per plant were decreased with the increase of soil salinity, which revealed that salinity stress reduced all the parameters of yield under different salinity levels. Among the genotypes the percent reduction of grain yield was higher in the genotype GPB-110 than   other varities. Sonalika   showed moderate reduction. The lowest reduction of grain yield was found in Ananda. 

Key words: Salinity, stress, wheat, genotypes.
