Common bean is the most significant pulse in Mediterranean countries and high yield performance is required to become commercially successful. Seven common bean genotypes were evaluated for yield and stability along with their interrelationship with agronomical, physicochemical and quality characteristics. An analysis of variance was conducted to test main effects and interactions between plant traits and environments. Significant variation among genotypes occurred for seed yield and a strong positive correlation was observed between seed yield and pods m-2. High Genetic Coefficient of Variation (GCV) values combined with high heritability for traits as seed yield, cooking time, hydration capacity and protein content were recorded. The GGE biplot analysis indicated two cultivars as superior genotypes that combine high yield, stability, short cooking time and high protein content. Furthermore, a local population assessed as promising genetic material for the selection of elite lines with high yield and short cooking time.

To compare the effects of varying seeding rate on the agronomic performance, phenology and seed quality of hybrid and conventional summer rape cultivars, four hybrid and two conventional summer rape cultivars were seeded at 1.5, 3.0, 4.5, 6.0 and 9.0 kg ha−1 at two locations for 3 yr. The hybrid cultivars were, very importantly, 24% higher yielding and produced 50% more total dry matter than the conventional cultivars. The hybrid cultivars were, on average, 1.3% lower in seed oil content, 1.0% higher in seed protein content and equal in sum of oil and protein in the seed compared with the conventional cultivars. The hybrid cultivars were on average, 1.3 d later to 50% flowering and 1.1 d later to maturity than the average for the conventional cultivars, (i.e., equal or earlier to flowering and maturity than Regent). The hybrid cultivars were also 3.9% lower in harvest index and 1.3 ppm lower in chlorophyll content than the conventional cultivars. In spite of these differences, there were no significant cultivar-by-seeding-rate interactions, indicating that the hybrid and conventional cultivars responded similarly to varying seeding rate. Lodging, days to 50% flowering, days to maturity, harvest index, survival, oil content and protein content displayed significant linear responses to varying seeding rate. Stand at maturity, seed yield and total dry matter production displayed significant linear and quadratic responses to varying seeding rate. Varying seeding rate had no effect on seed formation period, the sum of oil and protein content, or chlorophyll content. A seeding rate of 6 kg ha−1 maximized seed yield for both hybrid and conventional summer rape cultivars.Key words: Brassica napus, canola, seed quality, agronomy, phenology

ABSTRACT The objectives of this work were to study the genetic variability and the interaction between genotypes and environments for cooking time and protein content of bean grains as well as to identify elite lines of Carioca grain type with short cooking time, high protein content and high adaptability and stability for these two traits. Sixteen experiments were conducted in a complete randomized block design with three replications during the rainy, dry and winter seasons, in Goiás, Distrito Federal, Pernambuco, Sergipe, Bahia and Paraná States, in 2009 and 2010. Each trial was composed by 16 elite lines of Carioca grain type and the data of cooking time and protein content were obtained. Data were submitted to analysis of variance and to stability and adaptability analysis, according to the methodology proposed by Annichiarico. Genetic variability was found for cooking time and for protein content among Carioca common bean elite lines; however, for protein content this variability is lower. The environmental effect is important for the expression of these traits and is larger than the genetic effect. The interaction between genotypes and environments is important for cooking time and for protein content of common beans. The lines CNFC 11951 and CNFC 11962 presents short cooking time, high protein content and high stability and adaptability for both traits.

Industrial hemp (Cannabis sativa L.) has sparked renewed interest in western Canada in recent years, and there is very little research information available on its fertilizer requirements. The objective of this study was to determine the effect of surface-broadcast ammonium nitrate and seedrow placed monoammonium phosphate fertilizers on the production and seed quality attributes of industrial hemp (cv. Fasamo and Finola). Field experiments were conducted on a Black Chernozem silty loam soil at Melfort, Saskatchewan, Canada, in 2000, 2001 and 2002. Increasing N rates significantly increased plant height, biomass, seed yield and seed protein content of hemp in all years. Seed-applied P fertilizer increased plant height in all years, and biomass in 2000, but reduced plant density, biomass and seed yield in 2001 and 2002. Finola consistently had lower plant height, earlier maturity, heavier seeds, and higher seed yield, seed protein content and seed oil content than Fasamo. The average amount of nitrate-N in the 0–60 cm soil was 40 kg N ha-1. Seed yield kg-1 of N was 9.4, 5.9, 4.5 and 3.7 kg ha-1 for Fasamo, and 10.6, 7.7, 6.0 and 4.5 kg ha-1 for Finola, respectively, at 40, 80, 120 and 160 kg ha-1 of soil plus fertilizer N.

The method of allocation of zones of seed production of agricultural plants depending on soil and climatic factors is developed on the basis of the established four types of seed yield: type I - high yield, high seed quality; type II - high yield, low seed quality; type III - low yield, high seed quality; IV - low yield, low seed quality. Data on crop types were plotted on a contour map of the studied administrative subject (region, territory, republic) with the designated boundaries of districts and soil-climatic zones, as a result, 4 possible zones of seed production were identified: 1- the zone of optimal seed production, in which the seed farms form the I type of crop; 2 - the zone of risky seed production (II type of crop); 3 - the zone of permissible seed production (III type of crop); 4 - the zone of unacceptable seed production (IV type of crop). The network of seed farms should be organized primarily in the areas of optimal seed production. When organizing the production of seed material in the zones of permissible seed production, it is necessary to increase the yield by improving agricultural technologies. In the zones of risky (II type of crop) and unacceptable (IV type of crop) seed production, it is not advisable to produce seed material.

Abstract Background:Objective of the study was to investigate the response of groundnut genotypes to combined application of phosphorus and zinc on yield and nutritional contents. A field experiment was conducted at Sheka-Tekli in 2017/18 cropping season. Methods:The treatments were consisted of three groundnut genotypes (ICGV00308, ICGV91114 and Sedi) as main plot and four combined PZn fertilizer levels (00), 10 kg P/ha +0.50 g Zn/L, 20 kg P/ha +1 g Zn/L and 30 kg P/ha+1.5 g Zn/L as sub plot were assigned in split plot design with tree replications.Result: The result indicated that yield and yield components respond significantly to the main and interaction effects. The highest significant seed yield (2,529 kg/ha) and protein content (37.79%) were obtained in response to the application of P30Zn1.5 fertilizer on sedi variety in the loamy sand soil The percentage of crude protein and fat content had significantly affected by interaction components. Most of the yield component traits showed strong positive correlation with seed yield. While the lowest seed yield was recorded from ICGV00308 without fertilizer. The highest fat content (43.95%) was gained from genotype ICGV00308 at P30Zn1.5 fertilizer. From the interaction of sedi with P30Zn1.5 fertilizer was recorded highest protein content. Based on economic analysis the highest MRR (380.58%) was obtained from ICGV00308 genotype at P10Zn0.5 fertilizer. Conclusion: From the result of the study, application of PZn fertilizer increases seed yield of groundnut. Therefore, based on the MRR result ICGV00308 genotype at P10Zn0.5 fertilizer was optimum for groundnut production in the study area and similar agro-ecologies.

Seed Quality Traits

Landraces are a valuable source of genetic variability for breeders to develop high-yielding lentil varieties. Apart from productivity, simultaneous breeding for lentil seed nutritional quality is of paramount importance for wider lentil consumption. This work examined the indirect effect of single plant selection for high yield on important seed quality traits within three Greek lentil landraces (“Elassona” (EL), “Lefkada” (L), and “Evros” (EV)). The breeding methodology applied was proved to help either maintain or improve such characteristics in the high-yielding second-cycle lines (SLs) selected. Compared to the parental landrace “Elassona”, the high-yielding lines showed increased crude fiber by 30–110%; the line 2-SL-EL-6 had higher starch content by 3.9% and reduced cooking time by 6.67 min, while the 2-SL-EL-10 line had higher crude fiber by 73%. In the case of “Lefkada”, the high-yielding lines selected maintained the protein content present in the parental landrace, apart from the 2-SL-L-1 where a decrease by 5% was recorded; however, most of them showed increased crude fiber (5.59–7.52%) in comparison with the parental landrace (4.65%). Finally, in relation to the “Evros” parental landrace, the 2-SL-EV-3 and 2-SL-EV-4 showed higher crude fiber and reduced cooking time. This study provides evidence that proper management of genetic variability could improve productivity without compromising or sometimes improving some seed quality traits.

Cowpea [Vigna unguiculata (L.) Walp.] is a major legume crop and an important source of protein in Africa. The Kafr El-Sheikh University has a long history of cowpea breeding and improvement in Egypt. Two superior lines with high seed yield and quality were selected through mutation breeding and released to farmers as new varieties under the names Kafr El Sheikh-1 and Kaha-1. Crosses were made between these two varieties to further improve cowpea to meet farmers’ demand. Using the pedigree selection method, 13 new superior F10 lines were selected and evaluated over 2 years for seed yield and related traits, earliness, and protein content under low (16 plants/m2) and high (24 plants/m2) plant densities. The results showed that plants grown in narrower space produced significantly higher seed yield per unit area than the plants grown in wider space. All developed lines produced significantly higher seed yield than the two parental lines in the 2018 trial and Kaha-1 in the 2019 trial. Line number 6 proved to be the best genotype for earliness (73.5–73.9 days after sowing), seed yield (573–647 g/m2), and crude protein content (22.7–24.3%) in both trials. In addition, line 4 with bushy determinate growth habit and high seed quality was recently released as a new variety (Sakha-1). Several other cowpea lines have clear potential for release as new high-yielding varieties with early maturity and high seed quality for farmers in Egypt. Seeds of selected lines are available from Kafrelsheikh University. This shows that mutation breeding and pedigree selection methods are among the most promising breeding methods for cowpea improvement.

<p>Twenty genotypes of common bean including 17 breeding lines were evaluated for various seed physical, nutritional and culinary traits viz., seed colour, seed shape, seed brilliance, seed coat pattern, seed length, seed breadth and seed weight, traits protein content, phytic acid, raffinose, water absorption percentage, coat percentage, swelling and hydration coefficient as well as cooking score. Most of the genotypes were kidney shaped with plain seed coat and medium seed brilliance. Among biochemical traits, highest protein content was recorded for  Arka Anoop (22.15 %) followed by WB-341 (21.45 %), WB-216 (21.16 %) and WB-249 (20.99).  Low phytic acid was recorded in WB-970 (0.440 %), WB-258 (0.968 %) and WB-102 (1.068 %).  Low values for raffinose was recorded for WB-102 (3.800 mg/g) followed by WB-482 (3.833 mg/g). Highest water absorption percentage was recorded for WB-249 (136.363), Arka Anoop (131.818) and SFB-1 (126.923). The swelling coefficient was highest in case of WB-642 (300.000), WB-249 (266.667) and WB-335 (250.000) whereas lowest values for swelling coefficient were recorded in case of WB-341 (114.285), WB-216 (145.454) and WB-1006 (124.554). Among correlations between various seed physical, biochemical and culinary traits, raffinose was positively and significantly correlated with phytic acid. Phytic acid was also significantly and positively correlated with protein, coat proportion and 100-seed weight. Coat proportion was negatively correlated water absorption percentage, swelling coefficient, hydration coefficient as well as cooking time score. Cooking time score was positively correlated with hydration and swelling coefficients as well as seed weight but negatively correlated with coat proportion. </p>
