The present experiment was conducted with an aim to understand genetic variability and heritability among 30 soybean genotypes of different geographical locations during Kharif 2019 at TCA, Dholi, Bihar in Randomized Complete Block Design accommodating 30 genotypes randomly in three replicates. These genotypes evaluated for twenty-seven traits: five phenological, nine agro-morphological, eight physiological traits (from field trial) and five physiological traits from laboratory experiment recorded and subjected to statistical and biometrical analyses. Considerable variability was observed for these traits which revealed usefulness of existing genetic variability for all 27 attributes amongst which vigour index II, seedling dry weight, specific leaf weight and 100- seed weight was trust worthy (GCV in close correspondence with PCV; high h2bs & high GAM reflecting additive gene action) for selection criteria.

An experiment was conducted using a randomized complete block design to estimate genetic variability of ten rice genotypes. Analysis of variance for yield and yield contributing traits showed significant (p<0.01) variation among the genotypes. Results of genetic analyses showed a higher phenotypic coefficient of variation compared to their corresponding genotypic coefficient of variation for all the traits measured, which indicates that the traits were influenced by environment. The magnitude of difference between phenotypic coefficient of variance (PCV) and genotypic coefficient of variance (GCV) was less for the traits indicating little influence of environment. The higher estimates of PCV and GCV were observed for number of filled grains panicle–1 (27.53; 26.84), number of unfilled grains panicle–1 (26.76;25.28) and plant height (23.14; 23.00) indicates possibility of genetic improvement through direct selection for these traits, while days to 50% flowering, days to maturity, panicle length, number of effective tillers plant–1, fertility (%), 1000 Seed weight and yield panicle–1 showed low PCV and GCV values indicating the need for creation of variability by hybridization or mutation followed by selection. High heritability values (>60%) along with high genetic advance and genetic advance as percentage of mean were found for all the traits indicating prevalence of additive gene action, which provides good scope for further improvement by selection.J.

Hybridization is the process on interbreeding between individuals of different species or genetically divergent individuals from the same species to produce new progenies with their uniqueness and differences, involving in Vanda. Aim of this research was to explore genotypic and phenotypic variability, heritability and genetic advance of progenies derived from hybridization of Vanda ‘Adrienne’ × Ascocenda ‘Peggy Foo’ with Vanda malinii × Vanda denisoniana Benson & Rchb.f, and to find best characters used for selection. The experiment was conducted at Segunung Experimental Garden of Indonesian Ornamental Crop Research Institute (IOCRI) on altitude of 1100 m above sea level from June 2013 until December 2016. Thirteen genotypes derived from hybridization of V. ‘Adrienne’ × A. ‘Peggy Foo’ with V. malinii × V. denisoniana of 1A, 2A, 21A, 27A, 50A, 52A, 98A, 101A, 102A, 113A, 116A, 120A, and 120B were used in the study. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications. Results of the study indicated that range of genetic variability was varied from 1.2-184.7% with wide genetic variability determined on number of leaves per plant (NLP) up to 26.5% with 184.7% for leaf width (LW) and 24.7% for spike length (SL). Moderate heritability of 25.2% for NLP, 21.0% for LW and 25.2% for SL coupled with high genetic advance percent of mean up to 59.7% for NLP, 939.7% for LW and 33% for SL, reflecting the presence and expression of additive gene action of these traits. The results indicated the importance of these three characters best used as selection criteria for Vanda genotypes.

A field experiment was conducted using twenty three rice genotypes including three check varieties during the period from June to December, 2013, at the Agronomy Field Laboratory, Department of Agronomy, Bangladesh Agricultural University, Mymensingh to study genetic variability, heritability and genetic advance (GA) for yield and yield associated traits in rice. The experiment was laid down in a randomized complete block design with three replications. Plant height, number of filled grains per panicle, days to 50% flowering, thousand grain weight, grain width and grain yield showed relatively high genotypic co-efficient of variation (GCV) and phenotypic co-efficient of variation (PCV) estimates. The PCV were higher than GCV for all eight traits indicating that they all interacted with the environment to some extent. High heritability was obtained for grain width (88.54%), followed by days to 50% flowering (87.61%), thousand grain weight (81.96%), grain length (81.94%), days to maturity (81.81%) and number of filled grains per panicle (78.19%) which indicates high heritable portion of variation. High to medium estimates of heritability and genetic advance were obtained for number of filled grains per panicle (18.97), days to 50% flowering (11.89), days to maturity (12.16) indicating the roles of additive gene action and a good scope of selection using their phenotypic performance. Considering, all of these characters, filled gains per panicle and days to 50% flowering and maturity were important yield related traits and could be used for selection in rice breeding programs.Progressive Agriculture 26:26-31, 2015

Soybean (Glycine max L. Meril) is one of the most important and well recognized oil seed and grain legume crops of the world. A field experiment was conducted to investigate the efficacy of BAU-Biofungicide (Trichoderma harzianum), Trichoderma based IPM Lab bio-pesticide and Bavistin against anthracnose of soybean. Five soybean cultivars viz. Sohag, BARI Soybean-6, BINA Soybean-1, BINA Soybean-2 and BINA Soybean-3 were used in this experiment. The field experiment was carried out following Randomized Complete Block Design in the field laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh. Anthracnose infections were found initially lower at 80 DAS, moderate infections were found at 95 DAS and the highest infections were recorded at 110 DAS in case of all the tested five soybean varieties. The highest percent reduction of anthracnose infected plants/plot over control was observed in Bavistin treated plot (76.25%) that was near to BAU Biofungicide treated plots. All the growth parameters of soybean plants such as plant height, number of pods/plant, seed weight/plant, yield/plot and yield/ha were increased significantly in BAU-Biofungicide treated plots that showed best performance in compare to IPM Lab bio-pesticide (2%) and Bavistin @ 0.2% when these treatments were applied two times with 15 days interval. However, anthracnose incidence was reduced significantly when all the treatments applied in this experiment and the effect of BAU-Biofungicide was found almost similar to Bavistin in reduction of anthracnose of soybean.Res.

Hand Weeding

The weed suppression ability of different soybean varieties was studied in a field experiment in 2010. The experiment was carried out in a randomized complete block design using a split-plot arrangement with 3 replicates. The main plots were either weedfree (hand weeding) or infested with the natural weed population (weedy). Six soybean varieties (Sari, Telar, Sahar, Hill, 032 and 033) were randomized within the main plots. The relative biomass total (RBT), relative crowding coefficient (RCCcw) and competitive balance index (Cb) were recorded and were regressed against crop traits under weedy conditions. The results showed a reduction in the maximum height of the soybean varieties under weedy conditions. No significant relationship was found between weed biomass and the canopy height of the varieties. Competition indices and the weed suppressive ability of soybean showed intergenotypic variation in competitive ability between the varieties tested. Weed pressure reduced the yield and yield components of all the soybean varieties. Under weedy conditions the soybean variety Hill gave a higher economic yield than the others, with high weed biomass suppression ability.

Background: Edible podded pea is an oriental vegetable crop which shares the cultivation pattern with the garden pea. Fresh tender pods lacking parchment layer are consumed whole like beans. It is a newly introduced crop in India and therefore, it would be imperative to identify the most promising genotypes vis-à-vis traits of interest, those contributing towards maximization of yield. The present investigation was, therefore, planned to assess the genetic parameters of variability for pod yield and related horticultural traits in order to identify the most promising edible pod pea genotypesMethods: Thirty six genotypes comprising of 29 F7 advanced breeding lines and nine lines from different institutes including three checks namely, ‘Arka Apoorva’, ‘Arka Sampoorna’ and ‘Mithi Phali’ were evaluated in randomized complete block design over three replications during winters 2016-2017 at C.S.K. Himachal Pradesh Krishi Vishvavidyalaya, Palampur for pod yield and related horticultural traits.Result: Sufficient genetic variability was observed for all morphological and yield contributing attributes. The magnitude of phenotypic (PCV) and genotypic (GCV) coefficients of variation were high for pod yield while branches per plant, internodal length, harvest duration and pods per plant showed high PCV and moderate GCV. High heritability along with high genetic advance was observed for internodal length, plant height, average pod weight and pod yield per plant indicating the importance of additive gene action. Pod yield per plant revealed positive correlation at both phenotypic and genotypic levels with pods per plant, average pod weight, pod length and pod breadth. Pods per plant and average pod weight at both phenotypic and genotypic levels had maximum positive direct and indirect effects to the total association of component traits suggesting the importance of these traits towards pod yield.

Crosses were made in line × tester mating design between a set of five IITA soybean released varieties and three plant introduced (PI) accessions obtained from World Vegetable Center, Taiwan. In order to produce sufficient seeds, F1 crosses were selfed, subsequently F2 populations along with their parents were planted in a randomized complete block design at two locations in Nigeria with three replications. Agronomic traits viz. days to flowering, days to poding, plant height, number of pods/plant and seed yield/plant were measured. Testers and lines showed significant differences for all the measured traits except days to flowering for testers. Considering the significance and magnitude of general combining ability (GCA) effect, line TGx 1988-5F was observed desirable for earliness, while line TGx 1989-19F was the best combiner for number of pods/plant and seed yield/plant. On the other hand, best tester for seed yield was PI 230970. Crosses TGx 1835-10E × PI 459025B and TGx 1987-62F × PI 459025B had significant and highest SCA effect for seed yield/plant. These two crosses appeared to be most promising for soybean yield improvement programme.
