Book excerpt: The project combining ability and heterosis in a study involving 6 parents and 15 f1 hybrids of rice revealed that among parents, nlr 33654 recorded high per se performance and desirable gca effects for grain yield per plant followed by total number of productive tillers per plant. among 15 f1 crosses, nlr 33654 x mtu 4870 recorded the high per se performance and sca effects for grain yield per plant, total number of productive tillers per plant and number of grains per panicle.

This book was released on 2012-11-27 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2012 in the subject Biology - Genetics / Gene Technology, Tamil Nadu Agricultural University (Madurai Agricultural College and Research Institute), course: Ph.D, language: English, abstract: An investigation in rice (Oryza sativa L.) was carried out subjecting six ‘lines’ and 15 ‘testers’ crossed in a Line x Tester mating design to estimate gene action, combining ability and heterosis for yield and drought tolerant traits under aerobic condition. The 21 parents were also surveyed using SSR markers. From the Line x Tester analysis, the hybrids exhibited significant variation among themselves for all the characters studied under aerobic condition. The study of gene action for drought tolerance and yield component traits revealed that all the traits exhibited dominant gene action which was predominant. Therefore, to harness the dominant gene effects, either heterosis breeding or selection at later generations would be an appropriate breeding methodology. Based on the per se performance of lines and testers, the following parents i.e., IR79128A (L1), IR79156A (L2), COMS14A (L5), COMS24A (L6), IR 80286-22-3-6-1R (T3) and IR7925A-428-2-1-1R (T4) were adjudged as the best parents and crosses involving them would be expected to throw desirable segregants for both yield and drought tolerant traits under aerobic condition. Based on the gca effects, the parents IR79128A (L1), IR70369A (L4), IR79156A (L2), BI-33 (T15), IR79582-21-2-2-1R (T5), KMP-105 (T11), T1 (IR 69726-29-1-2-2R) and MAS - 946-1 (T9) were the best general combiners and the crosses involving them would result in the identification of superior segregants with favourable genes for both drought and yield. Out of 21 parents evaluated based on per se and gca effects, three ‘lines’ viz., IR79128A (L1), IR79156A (L2) and IR70369A (L4) and three ‘testers’ viz., IR7925A-428-2-1-1R (T11), KMP -148 (T12) and BI-33 (T15) were identified as the best genotypes which will be utilized in further breeding programmes as parents for improvement of yield and drought tolerance under aerobic conditions. The cross combination IR70369A / MAS -26 (L4 x T10) was identified as the best for recombination breeding to get desirable segregants for yield and drought tolerant traits under aerobic conditions. The cross combinations viz., IR70369A / IR 7925A-428-2-1-1R (L4 x T4) and IR70369A / KMP-105 (L4 x T11) had high per se, sca effects and standard heterosis for drought tolerant and yield traits under aerobic conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Genetic Enhancement of Rabi Sorghum – Adapting the Indian Durras presents both the historical background and the recent research done in breeding this important world crop for more global production. Its chapters cover topics in origin and taxonomy, morphology and breeding behavior, genetics, and cytogenetics, also looking at production, nutrition, and alternate uses. The durra race is Ethiopian in origin and its introgression with wild forms permitted adaptation to drier conditions. These have migrated and adapted to the currently known crop that is cultivated in the winter season and commonly called rabi sorghums. Grown under receding soil moisture conditions, rabi sorghums have tolerance to abiotic stresses apart from biotic stresses, unlike the rainy sorghums that are grown widely in the world. However, they must be more resilient to rapid changes in climate, for example. The variability from winter sorghums is being introgressed into rainy sorghums. With the yield plateaus reached and sorghum gaining importance as a food crop, this book will be of importance to those studying durras and their breeding. - Presents both the historical background and most recent research done in breeding rabi sorghum for more global production - Provides information on the adaptation of the crop and the ways it has migrated to the currently known crop, which is cultivated in winter season and commonly called as rabi sorghum - Explores strategies for resilience as the crop must be prepared to withstand rapid and varying changes in climate
