Abstract
利用早晚熟性之isogenic系統的水稻為材料，藉各性狀頻度分布之圖形來描述雜種集團之米粒蛋白質含量及其他農藝性狀之遺傳變異。結果獲知早熟系統為相對短稈、穗短而輕之品系，並觀察到米粒蛋白質含量、株高、穗長及穗重等四性狀與抽穗期之早晚有某種關係存在，而早熟基因團則不影響原遺傳因子型之分蘗能力。文中並曾就各性狀之頻度分布圖形來初步描述各該性狀之族羣特徵。
Genetic variation of protein content and various agronomic traits in the hybrid population of early x late isogenic lines was studied. Variation in protein content and other traits in F2 varied greatly from different cross combinations. From the F2 distribution curve in comparison with that of parental lines, it is assumed that the low protein content is dominant over high protein content. Early maturing is found to be related with high protein content. Further, genetic variations of plant height, panicle number, panicle length, panicle weight, percent seed setting and 1,000 kernel weight were studied with regard to skewness and kurtosis of respective populations.
