This book was released on 1970 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effectivinese of early generation testing for combinig ability for grain yield in grain sorghum restorer lines was studied at College Station, Texas, Two well-Known restorer lines, TX 7078 and TX 09, were crossed and resulting F@, F$, and F^ segregates were evaluated for combining ability. In the F2 population, 70 F2 plants were crossed to each of four male-sterile lines, A Tx 3197 (Combine Kafir-60), A Tx 398 (Martin), A Tx 378 (Redlan), and A Tx 3048 (Redbine sel.). These "F2 hybrids" were grown in a replicated test in 1962. Based on the mean yield of the four hybrids with each F2, 12 high- and 12 low-combining F2's were selected for advancement to the F4 generation. The F4 lines from each of these 24 selected F2's were crossed to each of the same four male-steriles and the hybrids tested in 195=63. Three high-and three low-combining F2 families were closen for further study in the F6. The F6 lines were crossed of the same four male-steriles and the hybrids tested in 1964. By compring, within families, the yield of "F2 hybrids" with the yield of "F4 hybrids" and "F6 hybrids, the effectiveb=ness of early generation testing for combining ability was estimated. High-combining F2's produced F4 lines and F6 lines that were significantly higher in combining ability than the F4 and F6 lines derived from low-combining F2's. Correlation coefficients for yield between "F2 hybrids" and "F4 hybrids', F2 hybrids" and "F6 hybrids"' and "F4 hybrids" and F6 hybrids" were generally large, positive, and significant (...).

Download or read book The Relationship Between Phenotypic Values in Male sterile Sorghum Parents and in Their F1 Hybrids written by R.R. Muyco and published by . This book was released on 1985 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty grain sorghum (Sorghum bicolor (L.) Moench) hybrids were generated by crossing each of ten cytoplasmic male-sterile lines with three diverse tester lines. The parents and their hybrids were grown in four replications at the Central Experiment Station during the 1983-1984 dry season. The study aimed to determine the relationship between the male-sterile parents and their F1 hybrids, identify the appropriate male testers for evaluating the combinig ability of male-seterile parents, and identify sorghum hybrids with potential for comercial use. Agronomic characters measured included grain yield, days to 50% bloming, plant height, 1000-seed weight and average number of seeds per head. The analysis of vriance showed that parental lines as well as their F1 hybrids were all significantly different for the five characters measured. Parental lines contributed a major portion of the total variation. Grain yield was found to be the most heterotic character. Male-sterilie parents were highly correlated with their F1 hybrids for days to 50% blooming, plant height and average number of seeds per head. But F1 hybrids approached their male parent in days to 50% blooming and were generally taller than their parental lines. Correlation values for grain yield and 1000-seed weight were positive but not high enough to be significant. The top yielding male-sterilie lines were positive for general combining ability effects for yield, days to 50% blooming, and average number of seeds per head. These lines were ATX622, (...).
