Correlation Study with Path analysis was performed on 29 Lentil Genotypes to determine direct and indirect effect of some morphological as well as Biochemical parameters on Yield. Following traits were studied: Root Nodule number, Nodule weight, Primary Root Length, Secondary root numbers, Root Fresh and Dry weight, Plant Height, Pods per plant, Days to 50% Flowering, 100 seed weight, Leaf chlorophyll content, Seed Carbohydrate with Starch content, Seed Protein content and Yield. Considering both genetic Advance and GCV, it was observed that selection for the following characters viz. Plant Height, Pods per plant, Days to 50% flowering, 100 seed weight, Seed Protein content & Yield will be rewarding. Seed Yield per plant showed significantly Positive correlation with the following traits: 100 Seed weight, Pod number per plant, Plant height and seed starch. Negative association with yield was found for Days to 50% flowering. Path coefficient study revealed that there was a strong positive direct effect of 100 seed weight and Pod no. per plant along with Leaf Chlorophyll content on Yield. Hence, direct selection only for Pods number and 100 seed weight will be rewarding as these characters also gave higher heritability % along with high Genetic advance. Plant height gave strong negative direct effect on yield, but it gave a positive correlation due to high indirect effect in association with pod number. It may be due to short winter span of West Bengal which results into forced maturity of the crops. So short plants with higher pod numbers will be desirable for higher yield in short winter span condition.

A field experiment was conducted at the Agriculture Faculty Farm of Sebha University during the 2007/2008 and 2008/2009 winter seasons to study the agronomic performance of seven pea genotypes with different sowing dates in sandy soil. The experiment was laid out in a randomized complete block design (RCBD) using a split-plot arrangement with three replicates. The five sowing dates (30 October, 15 November, 30 November, 15 December and 30 December) were assigned to the main plots, while the seven pea genotypes (Ambassador, Pollon, MG130256, G22765-2c, 89-P-109-11, No. 252, Victory Freezer and Master B) were allocated to the sub-plots. The sowing dates had a significant effect on all the studied traits except seed protein content in both seasons. Early sowing (15 November) was better than the other sowing dates for all the traits except 100-seed weight. There were significant differences between the pea genotypes for all the traits in the two growing seasons. The Victory Freezer genotype surpassed the other genotypes for all traits except number of branches plant-1 in the second season, 100-seed weight and seed protein content. The highest values for number of branches plant−1 in the second season and for seed protein content were obtained for the G22765-2c genotype, while the maximum values of 100-seed weight were recorded for the MG130256 genotype. A significant interaction between sowing dates and pea genotypes was detected for the length of the period from emergence to initial flowering, number of pods plant−1, seed yield plant−1 and seed yield ha-1 in both seasons. The longest period from emergence to initial flowering was obtained for the Victory Freezer pea variety sown on 30 November, while the highest values of pods plant−1, seed yield plant−1 and seed yield ha−1 were gained by sowing the Victory Freezer pea genotype on 15 November.

The study of the effect of three well known mutagens, ethyl methane sulphonate (EMS), methyl methane sulphonate (MMS) and gamma rays (GR) on the yield contributing traits of the urdbean variety TPU-4 were carried out in the M3 generation. Effect of selected mutagenic treatments/doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05 and 0.01 M) and (GR) (30, 40 and 50 KR) on different yield contributing traits like plant height, plant spread, number of pods per plant, pod length, number of seeds per pod, seed yield per plant and 100 seed weight were analyzed in the M3 populations of the variety TPU-4. Seeds of M2 plants and control were harvested separately and sown to raise M3 population.. Genetic variabilty in the mutagen administered M3 progeny of the urdbean variety TPU-4 was analyzed by employing statistical methods. Data on mean values and shift in the mean of seven quantitative traits was evaluated on individual plant basis. The experimental findings revealed that concentrations / dose of the all these mutagens showed inhibitory effect on plant height, number of pods per plant, pod length and number of seeds per pod. Lower concentrations of mutagens exerted a promotory effect on plant spread, 100 seed weight and seed yield per plant while higher concentrations of these mutagens inhibited them to different extent.

Plant landraces represent a repository of a gene pool, local adaptation of their domestic species, and thereby are considered a great source of genetic variations. Such genetic variation can be helpful to mitigate the current and future food challenges. A total of 183 common bean accessions including three commercial varieties collected from 19 Turkish provinces were grown to record their morpho-agronomic variations and to evaluate the best performing accessions under multi-environmental conditions. Plant height, days to maturity, pods weight, seed length, and 100-seed weight were used to evaluate the best performing accessions under different environmental conditions. A wide range of variations for traits like days to maturity (99–161), plant height (21–168.7 cm), seed length (7.41–16.4 mm), seeds per plant (17.8–254.4), and 100-seeds weight (24.97–73.8 g) were observed and can be useful for breeding purposes. The analytic results derived from the first three eigenvectors suggested that plant height, plant weight, 100-seed weight, and days to flowering were biologically significant bean traits. Seed yield per plant was positively and significantly correlated with plant weight and pods weight. Genotype × environment biplot discriminated the studied common bean accessions based on their plant height and growth habit. Plant height, days to maturity, seed width, and first pod height were found highly heritable traits and were least affected by environmental forces. Among 19 provinces, accessions of Bilecik showed maximum pods per plant, seed yield per plant and 100-seed weight, while Erzincan and Sivas provinces reflected the prevalence of bushy and early maturing accessions. Information provided herein comprehensively explored the occurrence of genotypic variations which can be used for the development of candidate varieties responding to breeder, farmer, and consumer preferences.

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 comparative effect of 0, 0.2, 0.4, 0.6 and 0.8% Zn levels of zinc chelate (Zn-EDTA; 8% Zn) and zinc sulfate (23% Zn) applied as foliar sprays for assuaging zinc deficiency of chickpea cv. Gökçe was evaluated under field condition. The sprays were applied on the plants before blooming stage during 2012 and 2013 growing seasons and seed yield, yield components like plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and mineral concentrations (nitrogen, phosphorus, zinc and iron) in seeds were investigated. Plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and seed yield were investigated. The results showed that increased zinc doses caused an increase in Zn content of seed, while seed yield was not affected similarly. In general, plant height, pod number and seed number per plant increased by the application of zinc. Lower dose of Zn-EDTA and higher dose of ZnSO<sub>4</sub> gave higher yield components. Seed weight, harvest index and seed yield were not significantly influenced by Zn sources and doses; however, mineral concentration of seeds enhanced when Zn doses were increased. It was concluded that foliar application of zinc resulted in an increase in seed mineral contents rather than seed yield of chickpea. The dose of 0.6% with Zn-EDTA was the optimum combination for Zn enrichment in seed of chickpea.

<p>Genetic parameters are important in genetic improvement and variety development. This study aimed to determine the effective characters that can be applied as selection criterion in soybean breeding using genetic parameters. About 100 soybean genotypes were grown in the Muneng Agricultural Technology Research and Assessment Installation from April to July 2020. The trial was conducted using a randomized complete block design. The results showed that high genetic variability was found on days to maturity, number of branches per plant, number of productive nodes per plant, 100-seed weight, and seed yield. The high heritability was shown by days to maturity, plant height, number of branches per plant, and 100-seed weight. All phenotypic correlations were significant, except for the correlation between seed yield and days to maturity, plant height, number of branches, and number of productive nodes. The seed yield had no genotypic correlation with all agronomic characters observed. The genotypic correlation was only significant for plant height and number of productive nodes, number of branches and number of filled pods, as well as number of productive nodes and 100-seed weight. Therefore, the improvement of seed yield can be conducted through direct selection using the seed yield parameter or indirectly using the 100-seed weight.<br /><br /></p>

Segregating populations (BC1F3 and F3:4) from an interspecific cross (C. scarabaeoides × C. cajan) were evaluated for variability and association studies for yield and its component traits. In both the generations, high values of PCV and GCV were obtained for pods per plant, seed yield per plant and fruiting branches per plant. High estimates of heritability as well as genetic advance were observed for fruiting branches per plant followed by pods per plant and seed yield per plant. High heritability coupled with high genetic advance revealed the presence of less environmental influence and prevalence of additive gene action. Seed yield per plant had highly significant and positive association with pods per plant, fruiting branches and 100-seed weight. Path coefficient analysis revealed that pods per plant, fruiting branches and 100-seed weight contributing maximum towards seed yield per plant. The study revealed that fruiting branches and pods per plant could be used as selection criteria for improving yield.

Studies on genetic variability, correlation and path coefficient analysis were carried out with 38 accessions of cowpea (Vigna unguiculata L. Walp.) evaluated in two environments i. e. kharif 2013 (E1) and kharif 2014 (E2) at Research field of NBPGR, Regional Station Jodhpur, India. Analysis of variance revealed significant differences among the genotypes for all the traits. Genotypic coefficient of variation was highest for number of clusters per plant followed by number of pods per plant in both the environments. High broad sense heritability along with high genetic advance for seed yield per plant, 100 seed weight, pod length, number of pods per plant, peduncle length, number of clusters per plant, number of branches per plant and plant height indicated the presence of additive gene effects for these traits in cowpea. In both the environments seed yield per plant was positively correlated with 100 seed weight, pod length, number of pods per plant, number of clusters per plant, number of branches per plant and plant height. The highest positive direct effect registered by number of branches per plant followed by number of clusters per plant in E1 environment and by number of branches per plant followed by plant height in E2 environment. The traits like 100 seed weight, plant height, number of pods per plant number of clusters per plant and number of branches per plant were identified as selection criteria for obtaining good parental lines in cowpea breeding programmes.
