Assessment of genetic diversity in different genotypes of mustard (Brassica juncea L.)
Abstract
The present study is about the estimation of genetic diversity among oilseed cultivars based on morphological characterization to fill the gap between production and consumption of edible oil. The research was conducted during 2017-2018 in Randomized Complete Block Design with six genotypes like juncea Group, Mirpur bithoro-I, Samara road-II, UCD-5/12, P-53-126/40, Rainbow and JS-13 (check) repeated in triplicate at Oilseeds Research Section Tandojam to determine the mean performance and genetic diversity on different genotypes of mustard (Brassica juncea L.). The results showed that all the genotypes had dissimilarity and significant differences (P <0.01) for growth and yield performance for all parameters. Mean performance indicated that among the cultivars UCD-5/12 surpassed all genotypes for days to 75% flowering (58.33), branches plant-1 (7.53) and yield (1133.9 kg ha-1). P-53-126/40 and Rainbow showed highest values in plant population plot-1 (159.00) and day to 90% maturity (127.65). More number of pods plant-1 (544.8) and yield plant-1 (25.68 g) were recorded in Samara road-II. Mirpur bithoro-I and JS-13 indicated maximum plant height (162.27cm), seed index (1000 grain weight, g) (4.62) and oil content (36.54%) respectively. Considering the genetic distance, out of 15 pair of comparisons, 3 pairs showed the highest genetic distance which can extensively be utilized in heterosis breeding; however, 12 pairs of comparisons revealed narrow genetic distance, which may be proved useful in backcross breeding programs. In total, first three principal component accounted 80.1% variability, which is considered very high and could be utilized for further breeding programs in mustard.
