Abstract/ Executive Summary:

Ten black gram (Vigna mungo L) germplasms were evaluated through 11 morphological traits. Among the morphological traits pod weight (g) 8.81%, harvest index (7.72%), number of branches plant-1 (6.18%) and 100-seed weight (g) 5.24% had shown the highest level of coefficient of variation. Grain yield plant-1 had the highest heritability (99.43) and seed pod-1 had the lowest heritability (53.10). The relationship between physiological and yield contributing characters was studied through analysis of the correlation between them. In the present study, out of 55 associations, 38 associations were highly significant. Among them, 22 associations were positively significant and the rest 16 were negatively significant. Yield plant-1 was positively and significantly associated with pod plant-1, pod length, weight pod-1, harvest index and 100-seed weight but negatively associated with plant height, fresh weight and dry weight. The result of the present experiment had indicated that number of pod plant-1, pod length and 100-seed weight were most important characters which exhibited a positive correlation with yield plant-1. It was observed that biomass plant-1 (0.73) had maximum positive direct effects on yield plant-1 followed by pod plant-1 (0.37), Seed pod-1 (0.19) by path coefficient analysis. Plant height had negative direct effect on seed yield followed by dry weight, 100-seed weight and branch plant-1. Hence for increasing the seed yield in the parental generation, direct selection based on these traits would be more effective.

Keywords: Vigna mungo, Correlation coefficient, Physiological, Yield contributing traits

Location: The Experimental Farm, Department of horticulture, Bangladesh Agricultural University (BAU), Mymensingh, Bangladesh

Start Date: 00-02-2012

End Date: 00-05-2012

Program Area: Socio-economic and Policy

Commodity: Black gram

Objectives:

The objectives of (i) to study the correlation coefficients and path coefficients in order to formulate selection criteria for evolving high yielding genotypes and (ii) to estimate the contribution of yield components on yield and their association in blackgram.

Methodology:

The experiment was carried out at the Experimental Farm, Department of horticulture, Bangladesh Agricultural University (BAU), Mymensingh during the period of February to May 2012. The place is geographically located at about 24075' North latitude and 90050' East longitude (Khan, 1997). Plant materials: Ten Blackgram genotypes1 were used as experimental materials among which BARIMASH-1 BARIMASH-2 were collected from Pulse Research Division, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and the rest of eight germplasm (BD-10033, BD-10034, BD-10035, BD-10036, BD-10037, BD-10039, BD-10042 and BD10047) were collected from Plant Genetic Resource Centre (PGRC), Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur. Experimental design: The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The plot size was 100cm x 50cm with 3 rows. The distance regarding block to block was 50cm, plot to plot was 25cm, line to line was 15cm and plant to plant within rows was 3 cm. Data collection: Five plants were randomly selected from each unit plot for collecting data. The selected plants were marked and the following characters on plot and individual plant basis were taken. The criteria used in the recording of data were as follows: plant height (cm), fresh weight (g), dry weight (g,) branch plant-1 , pod plant -1 , seed pod-1 , pod length (cm), pod weight (g), 100-seed weight (g) and harvest index. Data analysis: The data were analyzed for variance, heritability and correlation and path coefficient analysis. Simple phenotypic correlation coefficients were calculated using PLABSTAT software version 2N (Utz, 2007).

Achievement/Findings:

Correlation and path coefficients analysis were carried out for ten blackgram genotypes.Genotypic effects were highly significant for all the characters in analysis of variance. Plant height(cm), fresh weight(g), dry weight(g,) branch plant-1, pod plant-1, 100-seed weight (g), harvest index and grain yield were highly heritable and seed pod-1 showed the lowest heritability and pod length (cm), pod weight (g) showed medium heritability. Analysis of correlation revealed that, the yield plant-1 was directly and significantly correlated with pod plant-1, pod length and 100-seed weight but negative significant relation had observed between plan height, fresh weight and dry weight. Number of pod plant-1 was significantly increased with pod length, pod weight, 100-seed weight. Among the yield contributing characters, plant height was directly correlated with fresh weight, dry weight and negatively but significantly correlated with pod plant-1, pod length, pod weight, 100-seed weight. Dry weight was directly correlated with branches plant-1, plant height. The highest positive direct effect was found between seed yield and pods plant-1, biomass plant-1 had maximum positive direct effects on yield plant-1, pod plant-1, seed pod-1, pod length, pod weight. So, increasing the seed yield in parental generation, direct selection based on these traits would be more effective.
