| その他の書誌記述: | Progenitors of three single corn hybrids werecrossed with 23 lines with the purpose of identifying donorlines for improving grain yield of AN1 x AN2, SSE232-33-30x SSE255-18-19 and SSE255-18-19 x M.L.S4-1. Lines per seand their crosses among hybrid parents were evaluatedseparately in three environments in Mexico during 1997.Statistically-significant differences for grain yield amongdonor lines for minimally-based estimations of favorablealleles μG and μ were found. The highest values offavorable alleles were detected in three tropical linesCML258, CML264 and CML273 and three subtropicalCML311, CML312 and CML319. The improvement of grainyield in each elite hybrid appears possible with several donorlines. The modified procedure of identify donor lines offavorable alleles μ , showed more efficiency than μGoriginal. |
