Abstract
本試驗以四個溫帶型馬齒種（Hi25、Oh545、UH-1及Pi77-4257，分別爲代號A、B、C及D）及四個熱帶型硬粒種（ICAL210、Hi28、CM103及CM109，分別爲代號E、F、G及H)，計八惆王米自交系爲材料，於民國73年春作，舉行全互交田問試驗，以探討個別玉米自交系之一般組合力，及粒型間雜交組合之特定組合力及雜種優勢，並探討13個農藝性狀與子粒產量間的關係，供育種上選育優良親本及高產雜種級合之參考。
全互交分析結果顯示，8個自交系及其28個F1雜種的子粒產量及除穗徑外的12個農藝性狀，均有極顯著的一般及特定組合力差異。一般組合力均方，除子粒產量外，均大於特定組合力均方。Each of four U. S. dent (Hi25, Oh545 , UH-1 and Pi77-4257, respectively coded by A, B, C and D) and tropical flint (ICAL210, Hi28, CM103 and CM109, respectively coded by E, F, G and H) maize inbreds were analysed in a diallel set for combining ability, heterosis, and the correlations among yield and 13 agronomic traits. Eight parental inbreds and their 28 F1 hybrids were included. Experiment was conducted in replicated blocks during spring crop 1984 at TARI.
