Sesame Genotypes

The identification of genetic variation, mean performance, and selection criteria for twelve sesame genotypes is required for the genetic enhancement of agronomic traits and seed quality. Thus, using a randomized complete block design with three replications, these genotypes were evaluated in a field trial at the Kafr-El-Hamam Agricultural Research Station, Agricultural Research Center, Sharkia Governorate, Egypt, and laboratory experiments at the Seed Technology Research Department, ARC, Giza, Egypt, during the two consecutive seasons of 2018 and 2019. For earliness in flowering, N.A.130 and Shandweel3 were the most promising sesame genotypes, while N.A.114 and RH1F3 had the heaviest weight of seed plant-1 and one or more yield-related traits, and NA114, Shandweel3, and Zahar12 had the best seed quality traits. Furthermore, Shandweel3 and M1A12 had the highest proportion of seed oil, Shandweel3 and Zahar12 had the largest amount of oleic acid, N.A.114 and RH1F3 had the highest content of linoleic acid, and Zahar12 and N.A.114 had the highest proportion of linolenic acid. Seed weight plant-1 can be improved through selecting genotypes having the lengthiest fruiting zone, more branches and capsules, and the high electrical values of seed conductivity, accelerated aging germination as demonstrated by selection criteria. Moreover, the oleic acid proportion had the greatest direct and indirect effect on seed oil content, demonstrating its relevance as sesame oil quality selection criteria.

Plant Sci. 91: 837–846. Hybrids are becoming the dominant cultivar type in Brassica napus L. to utilize the well-documented heterosis for seed yield in canola/rapeseed. While there are numerous reports of heterosis for agronomic traits in B. napus hybrids, there are few reports of heterosis for seed quality traits in this species. The objectives of this study were to determine if high parent or commercial heterosis for any seed quality traits occurs in high erucic acid rapeseed (HEAR) hybrids. Seed quality performance of 45 F1 B. napus HEAR hybrids, derived from crosses of 12 geographically and genetically distinct (based on known pedigrees) HEAR cultivars/lines, was assessed in the current study using seven HEAR cultivars/lines developed by the University of Manitoba (UM) and five proprietary European (EU) HEAR cultivars/lines. Replicated field trials to assess seed oil, protein, sum of oil and protein, glucosinolate, and erucic acid concentrations were conducted over six environments in Manitoba during 2004 and 2005. High parent heterosis and commercial heterosis for seed oil concentration up to 9% and up to 14%, respectively, was observed with hybrids displaying seed oil concentrations as high as 533 g kg−1. Low parent heterosis for protein and glucosinolate concentrations was also observed. Erucic acid concentration displayed commercial heterosis. Many hybrids displayed near zero percent heterosis for any seed quality traits; however, overall seed quality was maintained or increased even in these hybrids. The results of this study indicate that development of HEAR hybrids can be an effective way to improve seed quality components, especially oil concentration, in this crop.

Study Design: Randomized completely block design (RCBD) Place and Duration of Study: Agricultural Research Station, Halladkere, Bidar, Karnataka between 2016 and 2017. Methodology: A field experiment was conducted at Agricultural Research Station, Halladkere, Bidar to find out the best off season planting time for quality seed production of Soybean. The certified seeds of soybean varieties, JS-335 and Dsb-21 were sown with recommended package of practices at appropriate field condition from November to February at every fortnight with a spacing of 30 cm X 10 cm. The quality parameters related to seed were carried out in the laboratory of seed science department. Further, soybean seeds were treated with fungicide (carbendazim 25% + mancozeb 75%) at the rate of 3 gram per kg of seeds. Results: From the present investigation, it was observed that among the different sowing dates, soybean varieties (JS 335 and DSb 21) sown during 1st fortnight of November recorded significantly higher plant growth parameters as well as seed yield followed by 2nd fortnight of November during off season. Further, climatic factors like rainfall, maximum and minimum temperature and relative humidity played a major role in the off season to produce higher seed yield and quality of Soybean. Conclusion: Among various sowing dates, November 1st Fortnight sowing resulted in highest seed yield with better seed quality in both cultivars (JS-335 and Dsb-21) of soybean.

Development of new rice hybrids with high-yielding and superior in grain quality is the most important goal to enhance food security as well as to achieve consumer requirements. High seed costs and poor grain quality are the major limiting factors for adoption of hybrid rice. A practical way to improve hybrid seed quality and to increase production is possible to increase the seed setting rate through improving the floral traits for parental lines. In the context, the study was conducted at the Rice Farm and Laboratories of Sakha Agricultural Research Station, Sakha, Kafr El-Sheikh, Egypt in consecutive three rice growing seasons in 2015, 2016 and 2017. The study focused mainly on characterization of the new promising hybrid ‘G46A/GZ9399R’ and its parental lines. The cytoplasmic male sterile (CMS) line and restorer line were evaluated for twenty-three floral traits that influence outcrossing rate in hybrid rice under two seasons and there was a marked stability for most of these traits. As compared with commercial check variety ‘Giza 178’, the new promising hybrid ‘G46A/GZ9399R’ showed its superiority in all agro-morphological traits except plant height. This hybrid was very early, adapted widely and recorded 20.19% more yield than commercial check variety ‘Giza 178’. Instead, this hybrid produced superiority in all grain quality properties except grain length was medium grain and amylose content was equal for both studied genotypes compared to the check variety. In parallel, the assessment of genetic purity established the SSR markers RM154, RM331, and RM297, amplified alleles specific to differentiate parental lines of hybrid ‘G46A/GZ9399R’.

A two years field study was carried out in the research field and laboratory of Seed Technology Division, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during rabi season of 2008-10. The aim of this study was to determine the effect of five different dates of harvest viz. H1: 65 Days after emergence (DAE), H2: 70 DAE, H3: 75 DAE, H4: 80 DAE and H5: 85 DAE on the seed yield and viability of French bean. The experiment was laid out in randomized complete block design (RCB) with four replications. Results showed that the yield and yield contributing parameters significantly influenced the days to harvesting. The highest seed yields of 1.15 and 1.31 t ha-1 were obtained from the harvest of 75 DAE (Days after emergence) in 2008-09 and 2009-10, respectively. On the contrary, seed quality parameters like seed germination, root length and vigour index were also significantly influenced by harvest time. The highest seed germination percentage of 91.33 and 91.56 were recorded from the seed plots harvested at 75 DAE (pods are light brown with few yellow colour) both for the year 2008-09 and 2009-10, respectively. Similarly, the vigour indexes (12.49 and 11.64) were the highest in seed harvested at 75 DAE from the year of 2008-09 and 2009-10, respectively. This might be due to more food reserve and dry matter accumulation on the seed at later harvest. However, seeds harvested in 80 and 85 DAE were also found good for seed yield and seed quality.SAARC J. Agri., 13(1): 1-13 (2015)

The objective of this research was to determine whether phenotypic and genetic diversity could be identified for maize grain quality traits (percentage of starch, protein, oil, fiber and ash) and agronomic traits. 59 maize synthetic populations which differed in earliness and for geographic origins were evaluated in the field at the Agricultural Research Station Turda - Romania, for their per se value. Each synthetic population was tested only one year and was characterized for their ear characteristics and grain quality attributes. The grain oil and ash content showed high variability among genotypes. The experiment was conducted over 2 years (2006-2007) and 2 locations (Turda and Targu-Mures). Analysis of variance showed significant differences among the genotypes for all traits studied. General combining ability (GCA) effects were more important for grain content than specific combining ability (SCA). The occurrence of low interactions between synthetic populations and testers for all characters suggested the occurrence of high statistical additive effects expressed whatever the system of population evaluation. These results support breeding effort towards the genetic improvement of grain quality traits in “Turda” maize germplasm.

Mature seeds of three chickpea varieties like BARI Chhola-5, 6 and 8 were collected from three different branches like primary, secondary and tertiary, and were evaluated for quality in the Seed Technology Laboratory, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during August to September of 2004 and 2005. All the seeds were stored in earthen pot for five months before conducting the laboratory study. Significant variation was observed in all three varieties of chickpea for all the parameters studied except seed vigour. The highest moisture percentage (10.17 in 2004 and 10.18 in 2005), dry weight (0.50 g in 2004 and 0.51 g in 2005) and seed vigour (39.7 in 2004 and 41.6 in 2005) was observed in BARI Chhola-8 and the lowest in BARI Chhola-5. Germination percentage was significantly higher in BARI Chhola-5 (87.6 in 2004 and 88.9 in 2005). Seeds of different branches did not vary significantly for most of the parameters. However, seeds of primary or secondary branches had higher moisture and germination percentage, dry weight of seedling and seed vigour. Interaction effects of varieties and seeds of different branch had no definite trend though non-significant effect was observed in most of the parameters.

A field experiment was conducted to study the effect of sowing date on quality seed production of sweet pepper at the research farm of Seed Technology Division, Bangladesh Agricultural Research Institute, Gazipur, during 2011-2012. The aim of this study was to find out the optimum sowing date for quality seed production of sweet pepper. The treatments were 4 four sowing dates viz. 15 October, 30 October, 15 November and 30 November. Seeds were sown in seed bed for 1st sowing on 30 September, for 2nd sowing on 15 October, for 3rd sowing on 30 October and for 4th sowing on 15 November. The experiment was laid out in randomized complete block design (RCB) with three replications. The highest individual fruit weight, 1000 seed weight was obtained from the October 15 sowing date in the year of 2011-2012 and it was significantly different from all other dates of sowing. Maximum seed yield (86.2 kg ha-1) was recorded in 2nd sowing date (15 October) followed by 3rd sowing date (30 October) treatment while the lowest was found from 4th sowing date (15 November) (30.72, kg ha-1). Maximum seed quality as measured by moisture content, dry weight, vigour index and germination percentage were obtained at different sowing date. Maximum seed weight (mass maturity) was achieved at 1st sowing when average seed moisture contents were 5% and 4%, respectively. For high seed quality, sweet pepper is better sowing time at 2nd sowing time (15 October) which could be regarded as the point of physiological maturity.Progressive Agriculture 28 (3): 216-221, 2017
