The results indicated that the phenotypic variance for all the characters was considerably higher than the genotypic variance denoting little influence of environmental factors. Low genotypic and phenotypic coefficient of variation showed in plant height (6.36, 8.20) and thousand seed weight (4.58, 11.63). While moderate genotypic and phenotypic coefficient of variation was observed in seed yield (12.68, 18.09), number of branches per plant (13.71, 25.18), number of seeds per siliqua (20.20, 28.86). High genotypic (40.65) and phenotypic coefficient of variation (52.85) was observed for number of siliquae per plant. Low heritability with high genetic advance showed in plant height (0.60%, 8.85), number of branches per plant (0.29%, 0.54) and number of seeds per siliqua (0.48%, 6.75) indicating the possibility of non-additive gene action. High heritability with high genetic advance and high genetic advance in percentage of mean were observed in plant height (0.60%, 8.85, 10.16), number of siliquae per plant (0.59%, 31.93, 64.42), number of seeds per siliqua (0.48%, 6.75, 29.12) and seed yield (0.49%, 260.64, 18.32) which revealed the possibility of predominance of additive gene effects. Number of branches per plant had showed significant positive association with number of siliquae per plant (rg= 0.850**, rp= 0.795**) and number of seeds per siliqua (rg= 0.821**). On the other hand, it had significant negative association with thousand seed weight (rg=-0.912**) and non-significant positive and negative association showed with others characters. The results of the path analysis revealed that plant height (0.818) had the maximum direct effect and maximum negative direct effect was observed for number of seeds per siliqua (-2.558). However, the results suggested that some yield related traits such as plant height and thousand seed weight could be used in breeding program for the development of high yielding short duration B. rapa variety development in Bangladesh.

Obesity and diabetes are two disorders induced by poor eating choices. Consequently, there is an urgent need to develop modified foods that can ameliorate
such illnesses. The objective of this study was to explore the effect of Waxy genes on the structural and functional properties of starch, with the aim of improving food quality. Wild-type tetraploid wheat was compared with three mutants with different
Waxy gene combinations.
RESULTS: The proportion of B-type granules was higher in the mutants than in the wild-type (Wx-AB), and there were significant changes in the starch granule size, number, and phenotype in the Wx free mutant (Wx-ab). The lowest branch chain length was observed in Wx-ab, whereas Wx-AB had the highest branch chain length of DP ≥ 37. Wx-ab had the highest degree of crystallinity. The crystallinity trend followed the order Wx-ab>Wx-Ab>Wx-aB>Wx-AB. The amount of slowly digestible starch (SDS) was higher in native, gelatinized, and retrograded starch in the mutant. The amount of retrograded starch was closer to gelatinized starch than to native starch.
CONCLUSION: Waxy proteins make a substantial contribution to starch structure. A lack of waxy proteins reduced the unit chains markedly compared with the control. Waxy proteins significantly affected the smaller and longer chains of starch. The
lines with differing waxy composition had different effects on food digestion. The Wx-AB in native starch and Wx-Ab in gelatinized starch can control obesity and diabetes by slow-digesting carbohydrates and high resistance to digestion.

The field experiment was conducted using ten genotypes at College of Agricultural Sciences (CAS) of International University of Business Agriculture and Technology (IUBAT), Dhaka, Bangladesh during the Rabi season (November 2020 to March 2021). Treatments were using the randomized complete block design (RCBD) with three replications. Highly significant (p ≤ 0.01) differences among the tested genotypes were observed. The results obtained revealed that the mean squares of the genotypes (G6) were best for 50% flowering (50.38), days to maturity (122.08) and fresh pod shelling percentage (65.29%). Genotype (G2) had highest plant height (142.08 cm), pods plant-1(39.96) and seed yield plant-1 (52.04 gm). G9 had maximum 100-seed fresh (43.90 gm) and dry (21.29 gm) weight. Genotype (G5) had best primary branches plant-1 whereas G8 had maximum pod length (8.86 cm) and seeds pod-1 (6.26). The estimates of heritability and genetic advance were high for days to 50% flowering (0.99, 35.38%), plant height (0.95, 46.88%) and seed yield plant-1 (0.97, 62.47%). High heritability with moderate genetic advance were observed for days to maturity (0.97, 20.20%), pod length (0.95, 15.37%) fresh pod shelling percentage (0.82, 21.58%), 100-seed fresh (0.90, 29.52%) and dry weight (0.93, 22.68%). Significant and positive phenotypic coefficient of correlation was exhibited by seed yield plant-1 with plant height (rp = 0.64), days to 50% flowering (rp= 0.63), days to maturity (rp = 0.78), pods plant-1 (rp = 0.72), pod length (rp = 0.66), fresh pod shelling percentage (rp = 0.64), 100-seed fresh weight (rp = 0.65) and 100-seed dry weight (rp = 0.62). Significant and positive genotypic coefficient of correlation was exhibited by seed yield plant-1 with plant height (rg= 0.81), days to maturity (rg= 0.70) and pods plant-1 (rg= 0.84).

To identify the best genotypes for further breeding these genotypes were evaluated in a randomized complete block design with three replications. All genotypes were grown in 3m long ridges, which were kept 60cm apart where plant to plant distance was 30cm. To reduce experimental error, cultural practices were performed uniformly for all genotypes. Data was collected from ten randomly selected plants from each genotype in each replication. Highly significant (p ≤ 0.01) differences were observed for days to 50% flowering, plant height, primary branches plant-1 , days to maturity, pods plant-1 , pod length, fresh pod shelling percentage, 100-seeds fresh and dry weight, seeds pod-1 and seed yield plant-1.
