Genetic Analysis in Grain Legumes [Vigna radiata (L.) Wilczek] for Yield Improvement and Identifying Heterotic Hybrids

Abstract

Six mungbean parental lines and their fifteen F1s produced from half-diallel mating design were investigated for combining ability and heterosis in terms of a yield and its components. Results showed highly significant variations among the parents and F1s, suggesting a wide genetic variability for the studied characters. Analysis of variance indicated that genotypes mean square values, general combining ability (GCA) and specific combining ability (SCA) were highly significant (p ≤ 0.001) for all measured traits except for days to flowering, days to maturity, and pod length indicating genetic diversity of parents and both additive and non-additive gene effects in the inheritance of the measured traits. A higher effect of SCA than GCA for plant height and seeds per pod suggests the preponderance of non-additive gene effects in the expression of characters. Based on per se performance and GCA, BARI Mung-1, PS-7, and BMXK1-14004 were the best general combiners for yield per plant. In the context of SCA, hybrids BMXK1-14004 × Sonali mung, BMXK1-14004 × PS-7, BMXK1-14004 × BINA Mung-8, Sukumar × PS-7, and BARI Mung-1 × BINA Mung-8 were good specific combiners. BMXK1-14004 × Sonali mung and BMXK1-14004 × PS-7 were the best heterotic hybrids for yield and yield-contributing traits. These parents and crosses could be utilized for further use in breeding programs to improve yields in mungbean crops.

Genetic Variability, Character Association, and Path Coefficient Analysis in Transplant Aman Rice Genotypes

“…All studied genotypes displayed significant deviations across traits which specified a large array of variability among the traits. Similar deviations were also displayed in morphological traits [ 31 , 32 , 33 , 34 , 35 ], and other yield-contributing traits of different crops [ 20 , 36 , 37 ]. The selection of genotypes based on σ 2 p may be deceptive owing to environmental impacts.…”

Analysis of Primary and Secondary Metabolites, Physical Properties, Antioxidant and Antidiabetic Activities, and Chemical Composition of Rosmarinus officinalis Essential Oils under Differential Water Stress Conditions

“…After identifying the major families of primary and secondary metabolites through qualitative analysis, we performed quantitative assays on the secondary metabolites. Reliable methodologies cited in − were applied to quantify these metabolites. These established methodologies provide a robust framework for accurately measuring and determining the levels or concentrations of the identified metabolites in plant samples.…”

“…All the sample data of a trait were averaged for each treatment to obtain a replication mean [ 113 , 114 , 115 ]. The mean data of various traits were statistically and biometrically analyzed [ 116 , 117 , 118 ]. Data analysis and ANOVA were performed using Statistix software version 8.0, Tallahassee FL 32312, USA [ 119 , 120 , 121 ].…”
