This research was carried out in the Experimental Field of Tekirda đ Agricultural Faculty. Two common vetch varieties and 5 lines were sown with 150 seeds/m 2 plant density according to a randomised block design. Some important yield related characters such as plant height, number of branches, number of pods per plant, number of seeds per pod, pod width, pod length, 1000 seed weight, fodder and seed yield were examined. The results of variance analysis showed that the effects of genotype, year and their interaction on number of branches and number of pods per plant were all significant. In addition, the effect of year and variety on plant height and seed yield were found to be significant. Moreover, the number of seeds per pod, pod width and pod length were found to be significant in variety and year × variety interaction. There was only a difference between years for 1000 seed weight and fodder yield. According to the results, genotype 283 and Tokat had similar performance to that of commercial cultivars (Ürem, Kubilay). Especially the fodder and seed yield of genotype 283 were found to be higher than those of the cultivars (Ürem, Kubilay).

The experimental material comprised of forty eight genotypes consisting of five Mori based CMS lines and seven Mori based fertile lines crossed in line x tester mating design. The resultant thirty five hybrids along with their twelve parents and standard check (GDM 4) were evaluated in randomized block design at Castor-Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during, rabi 2018-2019. The analysis of variance for combining ability revealed that variance due to gca was significant for all the characters except number of seeds per siliqua, seed yield per plant and 1000 seed weight. Whereas, variance due to sca was significant for all the traits. This indicates significant contribution of hybrids for specific combining ability variance component. The ratio of σ2gca/σ2sca below than unity for days to maturity, siliqua length, number of seeds per siliqua, seed yield per plant, 1000 seed weight and oil content which suggested greater role of non-additive gene action in the inheritance of these traits. Among the parents, female SKM 9928 and Kranti were good general combiner for seed yield per plant, total number of branches per plant and total number of siliquae per plant. Whereas, male parent Mori 'R' 1-18 was good general combiner for seed yield per plant, total number of branches per plant and total number of siliquae per plant. Best three hybrids which possessed significant positive SCA effects for seed yield per plant were SKM 301 x SKM 303, SKM 9928 x Pusa Agrani and Kranti x Mori ‘R’ 1-18.

The research objective was to determine the growth and production of the fifth generation mutant soybean (M5) at the Lampahan Bener Meriah University Farm. This study used a non-factorial randomized block design (RBD) with three replications, where four genotypes of Kipas Merah mutants were tested and compared with Kipas Merah (their parents) and Grobogan variety (large seeds). The variables observed were plant height, number of branches, number of productive branches, days of flowering, number of pods, number of pithy pods, number of seeds, weight of seeds per plant and weight of 100 seeds. The results of this study indicate that the M5 mutant soybean genotype has no significant different on plant height at age 4, 6, 8 WAP, number of branches per plant aged 6, 8 WAP, number of pods, and number of productive branches per plant. The highest average plant height and the highest number of productive branches found in Kipas Merah (G0) varieties. Mutant soybean genotype M5 had a very significant effect on flowering age and seed weight per plot. The fastest flowering was Kipas Merah (G0) and the latest flowering was A11 (G4) and A14 (G5) mutants. The highest weight of 100 seeds found in mutant A11 (G4) about 18.585 g and no significant different with Grobogan variety (18.827 g). The highest seed weight per plot found in mutant A11 (G4) about 169.35g. Based on the results of this study, mutant A11 (G4) was the best growth and production of the tested M5 genotypes.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University to observe the effect of sowing methods and weeding regimes on the yield of sesame. The experiment comprised of two factors. Two methods of sowing i.e., broadcasting and line sowing (S2), and six weeding regimes- control (T0), weed free (T1), one hand weeding at 15 DAS (T2), two hand weedings at 15 and 30 DAS (T3), three hand weedings at 15, 30 and 45 DAS (T4) and application of Panida (Pendimethalin) herbicide (T5) at 3 DAS. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Almost all the yield characters of sesame were affected significantly due to sowing methods, weeding regime and their interaction. Result showed that the l ine sowing showed better performance regarding plant height (100.40 cm), number of branches (4.983) plant–1, number of capsules plant–1 (47.82), number of seeds capsule–1 (69.66), 1000–seed weight (2.96 g), seed yield (956.90 kg ha–1), stover yield (2167.0 kg ha–1), biological yield (3123.00 kg ha–1) and harvest index (31.45%) than that of broadcasting method. Also weed free treatment had the highest plant height (101.90 cm), highest number of branches (5.00) plant-1, highest capsule (47.08) plant–1, heaviest 1000–seed weight (3.28 g), highest number of seeds capsule–1 (76.22), highest seed yield (974.30 kg ha–1), stover yield (2947.0 kg ha–1) and biological yield (3922.0 kg ha–1) as compared to other treatments while unweeded plot had least significant effect among the whole yield and yield attributes of sesame. In case of interactions, both weed free treatment and herbicidal effect with line sowing methods produced the highest plant height, number of branches and capsules plant–1, seeds capsule–1, seed yield, stover yield and biological yield (109.80 cm, 5.967, 56.57, 81.53, 1054.0 kg ha–1, 3139.0 kg ha–1 and 4193.0 kg ha–1, respectively) as compared to other interaction combinations. The results of the study reveal that the weed free treatment along with line sowing would be the proper technique for higher production of sesame. But line sowing along with application of Panida herbicide would be the best combination for obtaining higher yield of sesame since it is not feasible for the farmers to keep their field weed free throughout all the growing periods.

The current investigation was carried out to examine the selection criteria for yield improvement in selected genotypes of Indian mustard. Twenty-four genotypes of Indian mustard were evaluated for seed yield and yield attributing characters with randomized block design with three replications. The analysis of variance showed significant differences among all the 24 genotypes against all the characters. The phenotypic and genotypic coefficient of variation were higher for most of the traits like seed yield per plant, number of secondary branches per plant and number of siliquae per plant. High heritability coupled with high genetic advance in percent of mean was registered for number of siliquae per plant, number of primary and secondary branches per plant, plant height, 1000 seed weight, siliqua length per plant and seed yield per plant suggesting predominant role of additive gene action for expression of these traits. The correlation study revealed that seed yield per plant was positively and significantly correlated with number of primary and secondary branches per plant, number of siliquae per plant, siliqua length per plant and 1000 seed weight at both phenotypic and genotypic level. The traits namely, number of secondary branches per plant recorded as highest positive direct effect followed by number of seeds per siliqua, number of siliquae per plant and plant height. Therefore, they may be carried out further evaluation in multilocational trials, biotic and abiotic stress like environmental conditions to check their stability and adaptability.

Abstract Rapeseed breeding programs are focused mainly on improving plant potential and seed yield. One of the ways to improve seed yield in oilseed rape is heterosis, which is hybrid vigor that results in a greater biomass, increased seed yield, and faster development. The purpose of this study was to estimate yield-related trait heterosis for single cross and three-way cross hybrids of winter oilseed rape (Brassica napus L.). A population of 60 doubled-haploid (DH) lines and two generations of hybrids were evaluated in field trials to assess six yield-related traits: plant height, number of branches per plant, number of siliques per plant, silique length, number of seeds per silique, and thousand seed weight. Heterosis effects for each trait were estimated by a comparison of the particular hybrid with: (1) the trait mean over both parents—mid-parent heterosis and (2) to the value of better parent—best-parent heterosis. Traits with clear positive heterosis and traits with varied heterosis were observed in this study. For the first group, we include plant height, silique length, and the number of seeds per silique—a large number of hybrids expressed significant positive heterosis for these traits, independent from the year of observations and the type of hybrid. For the second group, with varied heterosis, we can include the number of branches and siliques per plant and thousand seed weight. For these traits, hybrids exhibited both positive and negative significant heterosis, without a clear pattern for the years and types of hybrids.

Seven parents (CST2002, MT34, OS-Sel-2, TKG22, AAUDT9304-14-4, B67 and Rama), their 21 F 1 s and 21 F 2 s were grown in summer 2003 in a randomized block design with three replications. Heterosis and inbreeding depression were studied for seven important yield-contributing characters (plant height, branch number plant −1 , capsules plant −1 , seeds capsule −1 , 1000-seed weight, stick yield plant −1 and seed yield plant −1 ). Maximum heterosis for seed yield plant −1 over the mid- and better-parent was recorded in CST2002×TKG22 (43.30%) and MT34×B67 (27.22%), respectively. Mid-parent heterosis for seed yield plant −1 was due to cumulative heterosis for various important component traits, such as capsules plant −1 , seeds capsule −1 and 1000-seed weight. Inbreeding depression was highest for seed yield, followed by 1000-seed weight, capsules plant −1 , branch number and plant height, indicating the predominance of non-additive genetic effects. B67×Rama exhibited significant positive heterosis in F 1 , but non-significant inbreeding depression in F 2 for seed yield. This cross can be utilized as basic material for identifying better pure lines. The clustering pattern indicated that in general genetically diverse parents exhibited more heterosis, as evident in the majority of the crosses.

Three varieties and an irradiation-derived line of pigeonpeas were used as parents in five crosses as follows: P.I. 5690 X Kaki, P.I. 5690 X Saragateado, P.I. 5690 X 526, Kald X 526, and Saragateado X 526. The F2, F3 and parents of each cross were planted in the field at the Isabela Substation during 1966-67 in a randomized block design with three replicates. Genotypic variability was studied and genotypic and phenotypic correlations were calculated for all the crosses in the F2 and F3 generations. Genetic coefficients of variation and heritability estimates were computed for four traits in five crosses and for six traits in one particular cross. Frequency distributions are shown for date of flowering, plant height, and seed weight. There was much greater variation for all crosses, in general, in seed weight, plant height, and flowering date than in number of seeds per pod. With the exception of number of pods per plant the correlations between seed yield and other traits were not great enough to provide reliable indications for yield. The phenotypic and genotypic correlations between seed yield and number of pods per plant were high, above 0.90. However, their low heritability, 45.3 and 52.1 percent in F2 and F3 generations, tends to indicate that not too much progress could be expected for seed yield improvement by selecting for large number of pods per plant. Good progress by selection could be made by breeders in traits such as flowering date, plant height, and seed weight which showed high heritability values.

This research was conducted on 20 safflower genotypes and lasted 3 years (2014-2016) in the Central Anatolia Region of Turkey. The experiments were conducted in randomized block design with four replications. The relationships among yield 9 other traits in safflower genotypes were investigated. As the average of three years, the greatest seed yield (SY) was obtained from genotype G5 (PI 451952) with 3156.3 kg·ha-1. It was followed by genotypes G4 (PI 525458) and G9 (PI 306686) with 3013.2 and 2977.1 kg·ha-1, respectively. Among the standard cultivars, the greatest seed yield (2750.4 kg·ha-1) was obtained from the Dinçer cultivar. The greatest oil content (OC) was obtained from the genotype G11 (PI 537665) with 36.5%. It was followed by the genotypes G9 (PI 306686) (35.4%), G6 (PI 537598) (35.4%) and G14 (PI 560169) (35.3%). Oil contents varied between 29.1-36.5%. Yield-trait relationships were assessed through both correlation analysis and GT (Genotype by Trait) biplot analysis. Based on the results of the two approaches, plant height (PH), number of branches (NB), number of heads (NH) and thousand-seed weight (TSW) were identified as the most significant selection criteria for yield from safflower. The combined use of correlation and biplot analysis in the assessment of relationships among the traits improved the chance for success.

Feld experiments were conducted at four locations of Bangladesh (Manikgonj, Cumilla, Dinajpur and Joshore) to optimize sowing date for higher seed yield of jute in late sown condition. The experimental variables constituted with three genotypes (O-72, O-3820 and Acc.4311) and three sowing dates (31 July, 15 August and 30 August).Each experiment was laid out in a randomized complete block design with three replications. The treatment combinations were assigned randomly and afresh randomization was followed in each replication. Results showed that the genotype Acc.4311, O-72 and O- 3820 produced maximum number of branches (5.40, 4.90 and 4.40, respectively) plant-1 on 15 August sowing at Manikgonj. The genotype Acc.4311 produced higher number of pods plant-1 than other two genotypes (O-72 and O-3820) in all sowing dates andat all the locations. The highest number of seedspod-1 (220.80) was found from the genotype Acc.4311grown at Manikgonj which was statistically similar (196.90) with that of the same genotype sown on the same date at Joshore. The highest thousand seed weight (2.478 g) was recorded from the seeds of genotype Acc.4311 sown on 15 August at Manikgonj followed by same genotype at Joshore.Finally, the genotype Acc.4311 sown on 15 August produced the highest seed yield (2.478 t ha-1) at Manikgonjwhich was significantly higher than those of sown on 31 July and 30 August at the same location. As the genotype Acc.4311 was found outstanding sown on 15 August over locations, this genotype may be considered promising for higher seed yield of olitorius jute in late season. Bangladesh Agron.
