NOMAN, MD. ABDULLA-AL- Genetic diversity of 20 radish genotypes was studied for some morphological trait and yield. For this a field experiment was accomplished at experimental site of Sher-e-Bangla Agricultural University during November 2016 to January 2017. A high variation was observed for root color, leaf shape, presence of awn in the leaf, plant height, root length, root weight. shoot length, shoot weight, and first flowering DAS. Among these genotypes. the genetic variation was apparent for most of the character I Ike plant height, root length, root weight, shoot length, shoot weight. root dry weight, shoot dry weight and first flowering DAS that indicated the potential for crop improvement in these traits through selection. On the basis of plant height, number of leaf per plant. root length. root breadth, root weight. shoot length. shoot wcight, root dry weight, shoot dry weight, first flowering DAS, Days to maturity four distinct cluster were formed. Cluster IV (01. 02, 03, 05, 07, 08, 09, G14. 015, 016. 017, 018, 019) contain the highest number of genotypes followed by cluster III (010, 011, 012, and 013) and cluster I (04, 06). The lowest genotype presents in the cluster I only one. The highest cluster distance was between cluster I and cluster Hi which was 16.695 followed by cluster 11 and cluster lii which was 15.747. cluster I and cluster 11(15.496). cluster Hand cluster IV(13.538). cluster I and cluster IV(13.075). The lowest distant was observed between cluster Ill and cluster IV (4.311). No clustering was found on the basis of origin. The highest root weight was observed in 04 (BD-4289) which was under cluster H. The highest shoot weight was observed in 020 (13D-10435) possessed by cluster 1. Among the cluster the long distance was observed between I and cluster III (16.695) and short distance was between cluster Wand cluster IV (4.311). Taking into account the genetic diversity and other performance 04, 06, 07, 019. 020 were considered to be hopeful parents for potential hybridization effort.

REZA, SHAMIM An experiment was conducted to observe the performances of four tomatillo and two tomato genotypes under three different replications in same growing season. The factorial experiment included four tomatillo and two tomato genotypes viz. G1 (SAU tomatillo-1), G2 (SAU tomatillo-2), G3 (PI003), G4 (PI004), G5 (BD-7306), G6 (BD-7761) were outlined in Randomized Complete Block Design (RCBD). 20 days aged seedlings were transplanted to main field. The results showed that both the different tomatillos and tomatoes genotypes genotype G6 had the highest pH (4.90) and the lowest pH was found in the genotype G2 (3.80). The genotype G6 had the maximum vitamin C (26.58 mg/100g) whereas the minimum (0.00 mg/100g) was found from G3. The highest dry matter content was observed by the genotype G1 (1.20 g) and the lowest dry matter content was found in G5 (0.30 g). The highest brix % (5.800%) was observed in G4 whereas the lowest (2.617%) from G5. The genotype G5 recorded the highest lycopene content of the fruit (20.61 mg), while the lowest was observed by the genotype G4 (0.2833 mg) in case of 472 nm. In case of 502 nm the highest lycopene content of fruit was observed in genotype G1 (26.62 mg) and the lowest was observed in the genotype G4 (0.07667 mg). The maximum moisture percentage was checked in the genotype G5 (95.0 %) and the minimum was checked in the genotype G1 (77.67 %). The conducted study disclosed that high heritability coupled with high expected genetic advance as percent of means were observed in case of pH (95.05 % and 21.72 % respectively), vitamin C (97.69 % and 273.45 % respectively), dry matter content (87.39 % and 97.26 % respectively), brix (98.33 % and 65.26 % respectively), lycopene at 472 nm (97.88 % and 303.84 %) and lycopene at 502 nm (98.78 % and 251.89 %) respectively indicating good response to selection for these characters. Therefore, based on the quality performance of tomatillo and tomato genotypes, G1 could be selected for high dry matter content, high lycopene and more brix% in the fruit. But for vitamin C as well as fruit pH genotypes G6 could be selected. For bulky, that means with high moisture percentage as well as with high lycopene content, G5 could be selected.

JONY, MOHAMMAD An experiment was carried out at Sher-e-Bangla Agricultural University in Boro season with 31 advanced lines of Boro rice to identify the diversity among the advanced lines. The advanced lines were examined for fourteen yield and yield contributing characters. Significant variation was observed among all the advanced lines for all the characters studied. High heritability along with low genetic advance in percentage of mean were observed for number of primary branches per panicle, effective tillers per panicle, thousand seed weight and yield per hectare. Highly significant positive correlation of yield per plant observed for days to 80% maturity (0.34**), number of secondary branches per panicle (0.402**) and number of filled grain per panicle (0.565**). Path analysis indicated that, yield per plant had the highest direct effect through number of secondary branches per panicle (0.88), number of effective tiller per plant (0.77) and length of panicle (0.396). On the basis of D2-value the genotypes were grouped into five clusters. Cluster IV was the largest and containing thirteen genotypes followed by cluster I with eleven genotypes and cluster III with only one genotype. The highest inter-cluster distance was recorded between cluster I and II (110.55). The intra cluster distance was maximum (7.87) in cluster IV. The lowest inter-cluster distance was recorded between cluster II and IV (35.26). Cluster mean indicated that cluster I was important for number of effective tiller per plant (13.18), length of panicle (24.72), total number of spikelets per panicle (223.37), yield per plant (41.86) and yield per hectare (5.57). Cluster III was important for length of panicle (24.72), number of secondary branches per panicle (44.95) and thousand seed weight (29.22). Cluster V was important for early maturity (126.5, DAS), length of panicle (24.33) and total number of spikelets per panicle (235.13). Considering cluster distance and the agronomic performance, the inter genotypic crosses between (G13 and G28, G13 and G10, G12 and G21 to combine early maturity character with higher yield); (G22 and G28, G21 and G29, G24 and G10 to combine dwarf character with higher yield); (G5 and G1, G5 and G12 to combine thousand seed weight with number of spikelets per panicle) would be suitable for highest yield per plant for future breeding program. The genotypes G6, G17, G20 and G29 would be suitable for released as high yielding Boro rice variety for their short duration and high yielding characters.

PAUL, SUMANA An experiment was carried out during the Rabi season of 2015-16 at the research field of Sher-e-Bangla Agricultural University, Dhaka to assess the correlation, path coefficient and genetic diversity in 20 morphologically diverse accessions of Blackgram [Vigna mungo (L) Hepper]. Analysis of variance indicated significant differences among the genotype for all the traits studied suggesting prevalence of wide range of genetic variability and scope of selection for these traits, except days to 50% flowering. High PCV and GCV were observed for branches per plant, seed yield per plant, pods per plant and plant height. High heritability coupled with high genetic advance was observed for seed yield per plant, branches per plant and plant height indicating preponderance of additive gene action in the inheritance of these traits and selection would be effective. Seed yield per plant exhibited significant and positive correlation with pods per plant and hundred seed weight and insignificant positive correlation with branches per plant, pod length and seeds per pod at both genotypic and phenotypic levels. Through path analysis the direct effects were found to be positive and high for plant height, days to first flowering, pod length and pods per plant. Twenty genotypes were grouped into five clusters. Highest inter-cluster distance was observed between cluster I and III followed by cluster I and V. There was sufficient genetic variability among the genotypes for all the traits under study. Hence selection of these characters simultaneously would bring improvement in yield.
