DIFFERENTIATION OF WHEAT VARIETIES THROUGH MORPHOLOGICAL AND MOLECULAR APPROACHES TASNUVA, SHARMIN - E—- Genetic variation within species has been assessed by many methods and from several perspectives. In present thesis, both RAPD markers and morphology were successfully used to differentiate four cultivars of wheat named Bijoy, Prodip, Sourav and Shatabdi. Four distinct morphological characters were identified to differentiate four varieties. In lower glume beak length, at physiological maturity stage, distinctness was observed. In Bijoy it was almost rudiment (1-2mm), in Prodip its length was the highest (15-18mm), in Shatabdi it was medium 12-15mm and in Sourav it was small (8-10mm). In Zadok growth stage 25-29, a distinct difference was observed in four wheat varieties. Growth habit of Sourav was erect, Shatabdi semi-erect and Prodip intermediate. Heading days at Zadok growth stage were 68 for Sourav, 71 for Shatabdi, 63 for Bijoy and 60 for Prodip. Clum glaucosity was strong in Sourav, weak in Shatabdi and Prodip and medium in Bijoy. Among the eleven primers initially tested, two primers (OPA-02 and OPB-01) yielded comparatively higher number of amplification products with high intensity, minimal smearing and good resolutions with clear bands. All of them (100 %) were considered as polymorphic and no monomorphic band was found the primer OPA-02 produced 16 bands and the other primer OPB-01 generated 17 bands respectively. The present experiment produce 33 scoreable bands by using two primers (OPA-02 r produced 16 and OPB-01 produced 17 bands) and they were polymorphic RAPD markers. The result of RAPD marker was more distinct than the morphological marker for the differentiation of wheat varieties. Phenotypic characters were influenced by the environment but incase of molecular marker the reproducibility of RAPD markers were the same in the same reaction conditions. So RAPD marker was found as a potential, simple, rapid and reliable method to evaluate the genetic variation.

EFFECT OF IMPROVE FEEDING ON PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF CROSSBRED HEIFERS AND COWS SIDDIQUE, MD. SHAHRIOR Dairy cattle rearing is an inseparable and integrated part of the smallholder subsistence farming system. Dairy cattle production in Bangladesh is characterized by low productivity levels due to mainly genetic and nutritional constraints. It is a fundamental approach to provide good quality diets to dairy cattle for optimum production. Therefore the study was designed to compare the productive and reproductive performance of LocalxHolstein-Friesian (LxHF) and LocalxSahiwal (LxSh) crossbred heifers and cows under traditional feeding system and improved feeding system. A total of 100 crossbred heifers and cows (LxHF, 50 and LxSh, 50) were selected from three upazillas of Lalmonirhat District reared under improved feeding system or traditional feeding system. The productive performances like daily milk yield and lactation period and reproductive performances like age at first heat, services per conception, age at first calving, gestation length, post-partum heat period and calving interval parameters were studied by collecting data through a well prescribed questionnaire. The result revealed that among the productive parameters daily milk production were significantly (P<0.05) improved in the LxHF crossbred heifers and cows were managed under improved feeding system compared to the cows were managed under traditional feeding system. On the other hand, among the reproductive parameters, age at first heat, services per conception, post-partum heat period, calving intervals were also improved (P<0.05) in the crossbred heifers and cows were managed under improved feeding system than the traditional feeding system. Age at first heat, age at first calving and calving intervals in LxHF crossbred and services per conception and post-partum heat period in LxSh crossbred were slightly improved (but not significantly) by improved feeding system. Where daily milk production of LxSh crossbred cows and lactation period of LxHF crossbred and LxSh crossbred cows were slightly increased (P>0.05) by improve feeding. So, it is suggested that the productive and reproductive performance of crossbred heifers and cows may be improved by improved feeding system. In the socio-economic aspects of Bangladesh, it is crying need to improve the productive and reproductive performance of crossbred dairy cows. The present result revealed that the productive and reproductive performances of crossbred heifers and cows were higher under improved feeding system compared to the traditional feeding system. So it may be suggested that the farmers of Lalmunirhat District should provide improve feeding to their crossbred heifers and cows to achieve better performances.

DIETARY EFFECT OF HYDROPONIC SPROUTED FODDER ON PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF RABBIT OSMAN, ABDULKARIIM ALI The present study was designed to investigate the replacement of commercial concentrate feed by hydroponic maize and sesbania sprouted fodder in rabbit production and reproduction. A couple of experiments were conducted using new white Zealand rabbits at the Advance Animal Research Farm of Faculty of Veterinary and Animal Science, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh. In Expt: I, a total of 24 post-weaned young rabbits of 7 weeks old were selected to study the replacement of commercial concentrate feed by hydroponic maize and sesbania sprouted fodder. The rabbits were randomly divided into four dietary treatment groups (T1, T2, T3 and T4) T1 considered as control and fed with only commercially concentrate feed and T2, T3 and T4 denoted the rabbit groups fed the diet comprising of 75, 50 and 25% commercially concentrate feed (CCF) and 25, 50, 75% hydroponic sprouted fodders, respectively. The percentage of moisture, DM, ash, OM, CP, CF, EE and NFE (%) content of hydroponic sprouted maize fodder was 85.21, 14.79, 2.50, 97.5, 10.92, 5.30, 2.94 and 78.34%, respectively. The moisture, DM, Ash, OM, CP, CF, EE and NFE (%) content of hydroponic sesbania sprouted fodder was 90.54, 9.46, 3.41, 96.6, 37.26, 7.21, 3.71 and 48.41%, respectively. The ash, CP and CF (%) was higher in hydroponic sesbania than maize sprouted fodder but the NFE (%) was higher in hydroponic maize than sesbania sprouted fodder. In Expt. II, a total of 12 rabbit does were selected to study the replacement of commercial concentrate feed by hydroponic maize sprouted fodder to investigate the reproductive performances. The rabbits were randomly divided into four dietary treatment groups (T1, T2, T3 and T4). T1 considered as control and fed with only CCF and T2, T3 and T4 denoted the rabbit groups fed the diet of 10, 20, 30 % hydroponic sprouted fodders, respectively. The results revealed that effect of 50% hydroponic maize and sesbania sprouted fodder in replacement with commercial concentrate increased the final live weight, live weight gain, feed intake and feed efficiency of young rabbits, the cost effective analysis also showed higher benefit in T3 than other T1, T2 and T4 groups in Expt: I. while 20% hydroponic maize sprouted fodder in replacement with commercial concentrate improved the final live weight, live weight gain and feed intake, feed efficiency of rabbit does and improving total litter weight and individual kit weight in Expt: II A THESIS BY ABDULKARIIM ALI OSMAN Registration No. 1705170 Session: 2017-2018 Semester: January-June, 2018 [Submitted to the Department of Genetics and Animal Breeding, Faculty of Veterinary and Animal Science, Hajee Mohammad Danesh Science and Technology University, Dinajpur for partial fulfillment of the requirement of the degree] MASTER OF SCIENCE (MS) IN GENETICS AND ANIMAL BREEDING

STUDY ON VARIABILITY AND SELECTION AT F6 GENERATION IN WHEAT (Triticum aestivum L.) ROBLE, ABDULKADIR SHEIKH MOHAMUD An experiment was conducted at the central research farm, department of Genetics and Plant Breeding (25˚ 13’ latitude and 88˚ 23’ longitude, and about 37.5 m above sea level) of Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur to study variability of Wheat (Triticum aestivum L.) at F6 generation during the period from November 2017 to June 2018. The experiment included seven genotypes namely HSTU-57, HSTU-46, HSTU-30, HSTU-63, HSTU-15, HSTU-28, HSTU-19 and one check variety called BARI GOM – 28. The experiment was laid out in a Randomized Completely Block Design (RCBD) with three replications. Each block was subdivided into eight plots. Data recorded were days to 50 percent heading, days to 50 percent anthesis, plants per meter square, days to maturity, spikelets per meter square, plant height, tillers per plant, grains per spike, spikelets per spikes, biomass, 100-grain weight, harvesting index and yield per plot. All the data were statistically analyzed using the Rlanguage software program and mean differences were adjudged by least Significant Difference test (LSD). The results of the experiment revealed that there were a genetic variability and significant variations between genotypes were observed for all the characters. In case of main effects of genotypes, significantly the highest grain yield per plot (1.6 kg) was found in the genotype of HSTU-57 and the lowest grain yield per plot (1.22 kg) was recorded in the genotype of HSTU-19. Again, in case of thousand grain weight, it was significantly variation the highest thousand grain weight (44.32 gm) was observed in the genotype of HSTU-57 and the lowest thousand grain weight (32.55 gm) was recorded in the genotype of HSTU-30. Again, the highest biomass yield per plot among all genotypes (5.00 kg) was observed from the genotype HSTU-57 and the lowest biomass yield per plot among all genotypes (3.12 kg) was recorded from the genotype HSTU-19. The maximum population number of plants per meter square (63.67) was recorded from the genotype HSTU-57, whereas minimum population number of plants per meter square (35.00) was obtained from HSTU-19.
