In another nursery, 384 F 5 s derived form B × B crosses were evaluated and testcrossed onto A 1 –male-sterile line producing 359 F 6 seed and harvested their testcrosses. The selected progenies flowered in 75−100 days and had a plant height range of 1.1 to 2.0 m. In yet another nursery 93 F 5 progenies were evaluated producing 78 F 6 progenies and their testcrosses onto A 1 – male-sterile line during the 2005 postrainy season. The selected progenies flowered in 75−95 days and had plant height ranging from 1.5 to 2.5 m. From 140 postrainy season-adapted F 4 progenies evaluated, 241 F 5 s were produced. The selected progenies flowered in 74−97 days and had a plant height range of 1.1 to 2.5 m. Combining ability of hybrid parents: To identify the best combiners among the postrainy season-adapted B-lines and restorers and to identify good hybrid combinations, eight postrainy season-adapted B-lines (ICSB 6, ICSB 14, ICSB 51, ICSB 52, ICSB 215, ICSB 297, ICSB 592, ICSB 675) were crossed to eight postrainy season -based R- lines (IS 4504-1, M 35-1-19-1, M 35-1-69-1, M 35-1-16-1, M 35-1-25-1, BP Ent 14, SP 7521, SP 7523) in a Line × Tester mating design to produce 64 hybrids. These 64 hybrids were evaluated along with a hybrid check CSH 15R in a RCBD design during the 2005 postrainy season. Significant differences were observed among the lines and testers for days to 50% flowering, plant height, staygreen score, lodging score, grain yield and 100-grain weight. Significant line × tester interaction mean squares for grain yield, stay-green score and lodging score suggested the involvement of dominance and/or epistatic gene action. While ICSB 297 and ICSB 592 among the A-lines and M 35-1-19-1 and M 35-1-69-1 among the R-lines were good general combiners for grain yield, ICSB 6 and ICSB 52 among the A-lines and IS 4504-1 and Ent 14 among the R- lines were good general combiners for grain size. The hybrids, ICSA 215 × M 35-1-19-1 and ICSA 51 × IS 4504-1 were good specific combiners for grain yield. R-line development: From the seed parent development program for postrainy season adaptation, the advanced progenies with R-reaction were evaluated. A total of 605 F 3 s derived from high-yielding R × R crosses were evaluated, and 140 F 4 seeds were produced during the 2005 postrainy season, and evaluated during the 2006 rainy season to produce 36 F 5 s. Days to 50% flowering in the selected progenies ranged from 69 to 75 days and plant height ranged from 1.3 to 2.7m. From the 53 postrainy season-adapted F 5 progenies (variety × variety crosses) evaluated during the 2005 postrainy season, 31 F 6 progenies were produced and their testcrosses were harvested. The selected progenies flowered in 77 - 87 days and had a plant height range of 1.0 to 1.8 m. From the 63 (F 7 ) advanced selections, derived from postrainy season-adapted large- grain and high-yielding variety × variety crosses, 25 advanced progenies were produced and evaluated in a trial during the 2006 postrainy season. Restorer lines trial (RLT-2005R): A trial was constituted with 40 advanced breeding lines showing restorer reaction. The material in the trial includes the lines developed from the crosses involving postrainy season-adapted varieties (M 35-1, SPV 1359) and advanced breeding lines and the selections from M 35-1 bulk for evaluation for grain yield and other desirable traits in a randomized complete block design with three replications along with the checks Moulee and M 35-1. Compared to the check M 35-1 (2.1 t ha -1 ), 31 R-lines with a grain yield range of 3.1 to 4.7 t ha -1 performed significantly better for grain yield and seven of these were significantly superior to the check Moulee (3.2 t ha -1 ). The luster score among these 31 lines varied from 1.0 to 2.7 (M 35-1: 1.0, Moulee: 1.0), while the grain size varied from 1.7 to 2.6 g 100 -1 grains (M 35-1: 2.1g 100 -1 grains, Moulee: 2.4g 100 -1 grains).

Milestone 5A.6.1.1: Six new dual-purpose foliar disease resistant forage/sweet sorghum hybrid parents developed (BVSR, 2009) High-yielding designated hybrid parents with sweet stalk, and varieties and hybrids developed by crossing promising sweet sorghum A- and R-lines were evaluated in replicated trials during the 2005 postrainy season. Results of these trials are given below. Sweet sorghum B-line trial: Based on the performance of sweet sorghum B-lines evaluated during the 2005 rainy season, a total of 30 B-lines were selected and evaluated along with the checks NSSH 104 and SSV 84 in the 2005 postrainy season. ICSB 73 with 0.9 t ha -1 sugar yield performed significantly better than the best check NSSH 104 (0.74 t ha -1 ) for sugar yield based on Brix reading and juice yield, while ICSB 324 (0.7 t ha -1 ), ICSB 652 & 401 (0.6 t ha -1 ) and ICSB 24001 (0.5 t ha -1 ) were significantly better than SSV 84 (0.3 t ha -1 ). The performance of the lines for other traits is presented in Table 1. Sweet sorghum advanced B-line trial (SSABLT, 2006K): Based on the performance of B-lines in sweet sorghum B-line trial in 2004 postrainy season, 2005 rainy and postrainy seasons, PPV (Protection of Plant Varieties) trials in 2004 rainy and postrainy seasons, PPV trials in 2005 rainy and postrainy seasons, 75 B-lines were selected and evaluated during the 2006 rainy season along with the checks 296B and SSV 84. Three B-lines, ICSB 729 (3.3 t ha - 1 ), ICSB 722 (3.1 t ha -1 ), ICSB 321 (3.0 t ha -1 ) were on par with the check SSV 84 (2.7 t ha -1 ) for sugar yield. Among these, ICSB 722 (14 t ha -1 ) was significantly better than the check 296 B (10.9 t ha -1 ) for grain yield, while the rest of them were on par with 296 B, except ICSB 321. The performance of these lines for other traits is given in Table 2. Table 1.
