Abstract: Appropriate planting time of mustard (Brassica sp.) during winter determines the growth yield and quality of a particular cultivar. Since the shift of winter period over the last few years driven by climate change, a transformation in mustard cultivation is also observed. Thus, to study the extent of these variations we studied 6 mustard varieties (V1- Binasarisha-4, V2- Binasarisha-9, V3- Binasarisha-10, V4- BARI Sarisha-14, V5- BARI Sarisha-16 and V6- BARI Sarisha-17) under 3 different planting dates (D1-31st October, D2-10th November and D3-20th November) in the Magura district of Bangladesh to evaluate yield differences over sowing times. Field experimentation was set followed RCB (Randomized complete block) design. Data on growth and yield parameters were collected at various days after sowing. Outcomes noted that, most number of siliqua lant was obtained with treatment combination D3 × V5 (190.33), siliqua length with D3 × V2 (7.95 cm), number of seeds per siliqua by D3 × V6 (36.30), thousand grain weight by D1 × V1 (3.90 g). Hence, correlation study suggested that, seed yield was positively related to number of siliqua lant, siliqua length and number of seeds/siliqua. Though, BARI Sarisha-16 (V5) delivered top seed and stover yield in all sowing dates. But interaction effects depicted that planting on 10th (2.00 t/ha) and 20th November (1.99, 1.94 t/ha) gave similar seed yield like 31st October planting (2.31 t/ha) in addition, stover yield (6.70, 6.83 t/ha) also remained at peak with the later plantings (D2, D3). An increase in the tendency of life duration was noticed when sown on 20th November for most treatment combination. Overall, delayed sowing of mustard didn’t affect the yield and related attributes rather it accelerated to some attributes. Hence, rescheduling of optimum sowing time for mustard is now a time demanding concern with regard to weather change.

Abstract: An experiment was conducted to evaluate eighteen Brassica genotypes for various morphological characters and estimate association for yield and yield contributing traits. The experimented was executed following Randomized complete block design (RCBD) with three replications in the experimental farm of the department of Genetics and Plant Breeding, Bangladesh Agricultural University Mymensingh-2202. The nine yield attributing characters are studied in the experiment. The genotypes differed significantly for all the traits viz., days to 1st flowering, days to maturity, plant height, number of branches lant, number of pod lant, length of pod, number of seeds od, 1000-seed weight (g) and seed yield lant (g).Considering the two most important traits like early maturity and yield lant, BD-7114 performed best among the studied genotypes. Correlation coefficients among the characters were studied to determine the association between yield and it attributing components. A significant positive correlation was found between yield and its attributing characters namely with number of seeds od and 1000-seed weight. Path analysis revealed both direct and indirect effects on seed yield and revealed that number of seeds od had the highest direct effect on seed yield. The findings of the research could be exploited in future breeding programs for improving Brassica genotypes. Progressive Agriculture 30 (1): 39-47, 2019

Abstract: Plant growth regulators were used to test callus induction and in vitro regeneration in six rice genotypes (RM-AC-2, BRRI dhan89, BRRI dhan88, Nipponbare, Koshihikari and Zenshan97). Four different concentrations (1, 2, 3 and 4 mg/L) of 2,4-D for callus induction and three different concentrations (1,2 and 3 mg/L) of NAA with three doses (5,10 and 15 µ/L) of kinetin for callus regeneration were used to test the effect of plant growth regulators. This study found a high callus induction on MS medium enriched with 2 mg/L 2, 4-D. In cases of RM-AC-2, BRRI dhan89, BRRI dhan88, Nipponbare, Koshihikari and Zenshan97, callus induction frequencies were 92.7%, 87.8%, 84.6%, 82.9%, 86.2% and 62.9%, respectively. In the regeneration, it was found that an MS medium enriched with 2 g/L Kinetin and 10 µm/L NAA has the ability to induce increased regeneration of different rice varieties (RM-AC-2 (72.4%), BRRI dhan89 (66.9%), BRRI dhan88 (62.5%), Nipponbare (63.3%), Koshihikari (48%) and Zenshan97 (39.6%). From the regenerated plants, one plant of the RM-AC-2 genotype availed to complete its life cycle and generated 32 effective tillers and yielded 89g. This rice plant is very promising for high yielding rice variety development program in Bangladesh. The improved callus development and regeneration ability of this genotype might be helpful for future rice variety development and genetic transformation program.

Abstract: The potential of a crop to favorably respond to breeding programs depends on its existing nature and magnitude of genetic variability, heritability and genetic advance. An experiment was conducted with eighteen Brassica genotypes following Randomized complete block design (RCBD) with three replications at the field of the department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh, Bangladesh to estimate genetic ergence, variability ranges and contribution of each trait towards genetic ersity. Analysis of variance showed significant variation among the genotypes for all the studied yield and yield contributing characters. The phenotypic co-efficient of variation (PCV) was higher than the genotypic co-efficient of variation (GCV) for all the characters measured, indicated that the traits were influenced by environment. All traits showed high heritability (61.54% to 98.64%) which indicated possible improvement through selection. High heritability values ( %) along with high genetic advance and genetic advance in percentage of mean indicated prevalence of additive gene action, which provides good scope for further improvement by selection. The genotypes were grouped into four clusters, most of the genotypes were grouped into Custer I (8 genotypes), while cluster IV contained only one genotype. Considering the mean value, the cluster IV and Cluster II were ranked as the top groups in terms of yield and early maturity. High Heritability with high genetic advance in percentage of mean was observed for number of branches lant, number of pod lant, number of seeds od and yield lant and selection focused on these traits could be useful for future breeding program of Brassica. The genotype BD-7114 was the best performer considering all the studied traits especially yield and days to maturity which could be used as an important breeding material for the improvement of Brassica.

Abstract: A field experiment was conducted at subtropical region in Bangladesh to assess the contribution of morphological traits to variability in some NERICA mutant rice lines. The experiment was conducted following RCBD with three replications. Thirty-one NERICA rice genotypes (twenty-eight mutant lines along with three parents) of advanced generations were used. Data were collected on twelve morphological traits. The results of the principal component analysis showed that the first four components account for 80% of total variation giving a clear idea of the structure underlying the variables analyzed. This result was also supported by scree test. Cluster analysis using Ward's method classified the thirty-one genotypes into five distinct groups. The maximum inter-cluster distance was observed between clusters indicating the possibility of high heterosis if in iduals from these clusters are cross-bred. The results of PCA were closely in line with those of the cluster analysis. These results can now be used by breeders to develop drought tolerant high yielding rice varieties and new breeding protocols for rice improvement. Int. J. Appl. Sci. Biotechnol. Vol 7(3): 327-334

Abstract: Field experiment was carried out in Moddhochar Jabbar of Noakhali, Bangladesh during Boro season (December-April) 2018 to investigate the ameliorative effect of application of gypsum and transplanting method on the yield of BRRI dhan28 (V1) and BINAdhan-10 (V2)under salinity stress. The experiment comprised 3 factors Transplanting method, Variety and Gypsum. This variety was evaluated under two transplanting methods i.e., Furrow transplanting (T1) and Conventional transplanting (T2) and four levels of gypsum with control G0: control, G1: 50 kg ha-1,G2: 100 kg ha-1 and G3: 150 kg ha-1 .The experiment was laid out in a Latin Square Design (LSD) with three replications. Salinity level had significant negative effect on plant characters and yield of rice. Gypsum (@ 150 kg/ha) exerted positive significant effect on most of the plant parameters except number of non-effective tillers. Furrow transplanting method (T1) had positive significant effect on most of the plant parameters except panicle length and harvest index. Binadhan-10 shows better performance than BRRI dhan28 in case of yield and all yield contributing characters in the prevailing condition. The highest grain yield (6.63 t ha-1) found from T1V2G3 (combination of furrow transplanting method, Binadhan-10 and gypsum @ 150 kg/ha) and lowest (4.26 t ha-1) inT2V1G0 (combination of conventional transplanting method, BRRI dhan28 and gypsum @ 0 kg ha-1). It was calculated that the straw yield highest (8.14 t ha-1) in T1V2G2 (combination of furrow transplanting method, Binadhan-10 and gypsum @ 100 kg/ha) and lowest (5.61 t ha-1) in T2V1G0 (combination of conventional transplanting method, BRRI dhan28 and gypsum @ 0 kg/ha).

Abstract: Mustard is Bangladesh's leading oil crop, produced only during the winter (rabi) season. The sowing date is a key factor determining mustard's optimum growth and development. Because of global warming, gradual changes in season and weather parameters over time is creating a challenge in mustard cultivation. Thus, the present investigation assessed the role of different planting dates on several modern mustard varieties to disclose the optimum growth indicators necessary for elevated biological yield (BY) and harvest index (HI). Three planting times, viz. 31st October (D1), 10th November (D2), 20th November (D3) and six varieties viz. Binasarisha-4 (V1), Binasarisha-9 (V2), Binasarisha-10 (V3), BARI Sarisha-14 (V4), BARI Sarisha-16 (V5), BARI Sarisha-17 (V6) were put on a replicated factorial randomized complete block design (RCBD) during rabi 2019 at BINA Sub-station farm, Magura. At the final harvest stage, outcomes depicted that highest and lowest total dry mass (g lant) was produced by treatment D3× V5 (64.03) and D1× V1 (15.34), maximum and minimum absolute growth rate (mg lant/day) by D1× V5 (2389.10) and D2× V1 (184.50), most and least relative growth rate (mg/g/day) in D1× V4 (53.34) and D2× V1 (3.55), maximum and least crop growth rate (g/m2/day) with D1× V3 (55.60) and D3× V4 (20.04). BY was the peak (8.13, 8.71, 8.77 t/ha) under all plantings (D1, D2, D3) with V5 variety, but HI (44.96%) was most in variety V4 with D2 sowing. Therefore, correlation studies showed a significant positive relationship between biological yield and harvest index. Overall, BARI Sarisha-16 performed well in all three sowing times, and remarkably, BY was rising with delayed planting in the case of Binasarisha-9, Binasarisha-10, and BARI Sarisha-14. This implies that delayed planting might not h er yield but boost yield to some extent.
