玉米植株及子粒生長性狀之遺傳研究

Abstract

本試驗針對玉米子粒產量有關的植株及子粒生長性狀，利用Hayman全互交分析法，進行6X6全互交之基因作用遺傳分析。分析性狀包括吐絲期、成熟期、株高、葉片數、業面積、吐絲期之植株乾重、脫粒率、作物生長速率、子實產量、穗長、穗寬、子粒行數、每穗粒數、子粒深度、百粒重、子粒直線生長速率及子粒有效充實期等十七項性狀。試驗目的期將分析結果提供高產玉米育種上之參考。 The experiment was conducted for the purpose to investigate the quantitative inheritances of vegetative growth and kernel growth characteristics of maize in a 6X6 diallel sets analyzed by means of Hayman's diallel analysis method. Characteristics under analysis included days to silking, days to maturity, plant height, leaf number, leaf area, plant dry weight at silking, shelling rate, crop growth rate, grain yield, ear length, ear diameter, number of kernel rows, kernel numbers per ear, kernel depth, 100-kernel weight, kernel linear growth rate and kernel effective filling period duration, etc.
