| Summary, etc. | The research programme was carried out at the Department of Plant Breeding and Genetics, College of Agriculture, Vellayani during 1995-96. The objective was to assess the general and specific combining abilities and gene action involved in the inheritance of biological nitrogen fixation traits and yield components in blackgram, as a preliminary step for developing high yielding varieties with good biological nitrogen fixation capacity. The five lines, three testers and their 15 combinations were evaluated in a replicated field experiment and data on twelve characters were collected and subjected to line x tester analysis. The best general combiners for important biological nitrogen fixation traits were COBG305 and Pant U19 among lines and T9 among testers. The hybrid combination Pant U19 x T9 was the best specific combiner for these characters. In the case of number of pods and grain yield per plant, among. lines WBG-13 and among testers T9 were the best general combiners. The hybrids, LBG 17 x VBN 1 and WBG 13 x AKU4 were the best specific combinations for these traits. Considering the mean performance, sea effect and standard heterosis percentage Pant U 19 x T9 was identified as the best hybrid combination for nodule weight and nitrogen content at 50 per cent flowering. Regarding yield, the best hybrid was WBG 13 x AKU4. These superior combinations can be utilized further for developing improved blackgram varieties. |
