"Heterosis and combining ability for grain Fe and Zn concentration and agronomic traits in sorghum [Sorghum bicolor (L.) Moench]"^^ . "Studies on genetics and trait relationships with grain yield and other agronomic traits are critical for\r\nimproving the micronutrients content in the grain and it forms an effective strategy for breeding bio fortified\r\nsorghum. It greatly contributes to addressing micronutrient malnutrition in poor people who are\r\ndependent on sorghum as a staple food. Development of hybrids with high grain Fe and Zn and higher\r\nyield enables delivery of commercial products that address both food and nutrition while bringing profits\r\nto farmers. The present study was aimed at developing suitable breeding strategy and improving breeding\r\nproducts using gene action, heterosis and combining ability analysis for improving the grain Iron (Fe)\r\nand Zinc (Zn) concentration and grain yield in sorghum. This study was conducted in Line Tester mating\r\ndesign involving seven parents. A total of 12 new hybrids were developed by mating three lines with\r\nfour testers. The combining ability of the crosses indicated predominance of dominance variance than\r\nadditive variance for the agronomic traits such as days to 50% flowering, grain yield, grain Fe and Zn concentrations\r\nexcept for plant height and 100 seed weight. Higher magnitude of SCA than GCA variance for\r\ngrain iron and zinc concentrations indicated the importance of non-additive gene action in the improvement\r\nof nutritional traits. Hybrids exhibited heterosis for agronomic traits and for grain Fe concentration\r\nand grain Zn. Most of the traits showed significant positive heterosis over mid parent value indicating the\r\npredominance of dominant gene action except the trait 100 seed weight. Significant positive mid-parent\r\nheterosis for grain iron indicated that there would be an opportunity to exploit heterosis in improving for\r\ngrain Fe. But for Zn concentration, there is a limited possibility for exploitation of heterosis. This study\r\nsuggested that simple selection will improve plant height and 100 seed weight in sorghum but heterosis\r\nbreeding is more useful for improving grain yield. While both parents need to be improved for improving\r\ngrain Zn concentration, there is good scope for exploiting heterosis for improving grain Fe concentration\r\nin sorghum."^^ . "2020-08" . . .
