LINE X TESTER ANALYSIS OF QUANTITATIVE TRAITS FOR SHORT DURATION AND HIGH YIELDING OF BRASSICA RAPA IN BANGLADESH

Genetic Analysis of Combining Ability for Yield and Yield-Related Traits in Yellow Mustard (Brassica rapa L.)

Yellow mustard (Brassica rapa L.) improvement requires identification of parents and cross combinations with favourable combining ability for yield and related traits. The present investigation was conducted to assess genetic variability, combining ability, and gene action for yield and yield-contributing traits in yel...

GENETIC DISSECTION OF HETEROSIS FOR YIELD AND QUALITY TRAITS IN RICE USING LINE × TESTER METHOD

This study was conducted to assess the magnitude of heterosis for grain yield and associated agronomic and quality traits in rice (Oryza sativa L.) using a Line × Tester mating design. Three lines and eight testers were crossed to generate twenty-four F₁ hybrids, which were evaluated along with their parents and a stan...

GENETIC ANALYSIS TO ASSESS THE PARENTAL LINES FOR BIOMETRICAL TRAITS IN RICE ( Oryza sativa L.)

Genetic Dissection of Yield and Quality Traits through Line × Tester Analysis in Garden Pea (Pisum sativum L. var. hortense)

Combining ability and gene action for yield, yield components and quality traits were investigated in garden pea (Pisum sativum L. var. hortense) using a Line × Tester design involving 10 lines, three testers and 30 F₁ hybrids, with their corresponding F₂ generations. Analysis of variance revealed highly significant ef...

Genetic analysis of seed yield and related traits in Brassica Juncea L

Best parents and F1 hybrids were identified based on general combining ability (GCA), specific combining ability (SCA), and high heterotic performance by analyzing the yield characters of 19 Indian mustard lines crossed with three male parents (testers). Significant genetic variability was observed among genotypes for...

Line x tester analysis for combining ability, heterosis, and genetic parameters in tomato yield and fruit quality traits

Tomato (Solanum lycopersicum L.) yield in Ghana remains low ( ~7.5 t ha-1), far below the >40 t ha-1 potential of improved hybrids, due to limited adapted varieties, bacterial wilt, tomato yellow leaf curl virus, and poor shelf life under high ambient temperatures. The objective of this study was to evaluate the combin...
