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 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.

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).

Genotypic source of variations were significant for all characters in 168 genotypes including 7 checks of Indian mustard at 5% level of significance. Maximum seed yield per plant (g) and harvest index was recorded in MRNJ-82; whereas, the minimum days to 50% flowering and maturity were recorded in RVM-1 and MRNJ-5 respectively. In genotypes viz; MRNJ-36, RVM-2, MRNJ-59, JM-1, MRNJ-53 and MRNJ-35 had maximum plant height (cm), number of primary branches per plant, number of secondary branches per plant, number of siliqua per plant, number of seeds per siliqua and 1000 seed weight (g). Highest GCV and PCV were recorded for seed yield per plant which indicates for improvement through selection among these genotypes. High heritability along with high genetic advance as percentage of mean has been noticed for seed yield per plant and harvest index indicating less influence of environment and also the presence of additive, dominance and interaction among genes in the expressions of these characters. Low genetic advance along with low heritability estimate were observed for number of primary branches per plant and number of seeds per siliqua. This indicates the involvement of additive and non-additive gene actions in their inheritance.

Twenty eight hybrids developed by utilizing eight parents in 8 x 8 diallel mating design excluding reciprocals were evaluated in randomized block design with three replications for twelve characters in order to understand the combining ability and gene action in pigeonpea. The analysis of variance for combining ability revealed presence of additive and non- additive gene action. The ratio of gca/sca variance was less than unity which indicated the preponderance of non- additive gene action for action in the control of pod length, harvest index, protein content and leaf area. The estimates of general combining ability suggested that parents ICPL-87119, GT-103 and AGT-2 were good general combiners for seed yield per plant and its attributing characters while, hybrids UPAS-120 x GT-103, BSMR-853 x BANAS and BSMR-853 x GT-1 showed the higher order sca effect for seed yield per plant. These cross combinations can be potentially utilized in hybrid breeding programmes.

The present research was conducted during September 2018 to June 2019 at Floricultural Research Station, Hyderabad, India to examine the influence of different times of planting on seed attributes in Gaillardia pulchella local cultivars. The experimental design is Factorial Randomized Block Design comprising of two cultivars namely Local yellow (C1) and Local red (with yellow tip) (C2) and five times of planting namely, 1st week of October (T1), 1st week of November (T2), 1st week of December (T3), 1st week of January(T4) and 1st week of February (T5) with three replications. The plot size is 2×2m with spacing followed is 30 × 45 cm. The results revealed that, maximum number of seeds/inflorescence was recorded with T1 (1st week of October) and minimum with T2 (1st week of November). T4 (1st week of January) recorded maximum seed yield /hectare, seed yield/plot and seed yield/plant and minimum in T2 (1st week of November). Germination percentage was recorded maximum with T1 (1st week of October) and minimum with T5 (1st week of February). Among cultivars, significant variation was observed in germination percentage. C1 (local yellow) showed higher germination % than C2 (local red with yellow tip). Interaction effect between cultivars and different planting times was non-significant in all the characters. Hence, it can be concluded that the cultivars namely Local yellow and Local red (with yellow tip) performed well with respect to seed yield. T4 (1st week of January) gave higher seed yield among different planting times and could be the best time of planting for seed production in Gaillardia pulchella.

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.

Combining ability study was carried out in a 10 x 10 diallel set of dry beans (Phaseolus vulgaris L.) for seed yield and its component characters. The 45 F1s generated by crossing ten diverse lines and their parents were evaluated in Randomized Block Design (RBD) in two replications at three locations during Kharif, 2008. Analysis of variance revealed that both gca and sca were influenced by environments, which suggested that studies be conducted over environments to get unbiased estimates. The sca x environment interaction was greater than gca x environment interaction for most of the traits. The relative magnitude of gca and sca variation indicated that greater magnitude of sca variances for all the traits, indicating greater importance of non additive gene action for the inheritance of these traits. SKUA-R-607 and SKUA-R-608 showed high combining ability for seed yield and yield attributing traits. The most promising crosses in order of merit for seed yield were Shalimar Rajmash 1 x SKUA-R-607, SKUA-R-608 x SKUA-R-106 and Shalimar Rajmash -1 x SKUA- R-612. These promising crosses may be improved through conventional breeding methods such as biparental mating and diallel selective meeting, thereafter followed by pedigree method of selection, so as the tight linkage, if any, may be broken and transgressive segregants may be isolated.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.
