落花生之籽粒種皮顏色、莢果網紋及每莢粒數等性狀為重要的農藝性狀，
本研究以台南10號、H.I.9003、台南12號及EG PN-18等四品種（系）為材
料，進行遺傳分析，茲將其結果分述如下：
1.種皮顏色的遺傳分析，係以淡紅色種皮的台南10號和紅色種皮之H.
I.9003為親本行正反交，其F1世代之表現型不論正反交均表現紅色種皮，
F2世代之表現型亦均分離為3紅色：1淡紅色之分離比。再者，經後裔檢定
及測交試驗的結果，均顯示籽粒種皮顏色之遺傳係受單一基因之控制。
2.莢果網紋的遺傳係以淺網紋的台南12號和深網紋的EG PN-18為親本進行
正反交，其F1世代不論正反交莢果網紋均表現介於兩親之間的中網紋，而
F2世代之表現型亦均呈現1淺網紋：2中網紋：1深網紋之分離比，此項結
果顯示，莢果網紋之遺傳係受單一不完全顯性基因之控制。再者，後裔檢
3.每莢粒數的遺傳係以2粒莢的台南12號和3-4粒莢之 EG PN-18為親本進
行正反交，其F1世代的單株不論正反交，均以2粒莢為最多數，F2世代的
單株則均呈15（2粒莢）：1（3粒莢）之分離比。再者，以正反交F2世代
的2粒莢單株繁殖成之F3世代後裔系統，呈現7不分離：8分離之分離比，

The testa color, pod reticulation and number of kernels per pod
are important agronomic characters of peanut. To study the
inheritance of these characters in peanut, TN10, H.I.9003, TN12
and EG PN-18 were used as materials. Results were summarized as
foll
1.The reciprocal crosses of TN10 with rose testa and H.I.9003
with red testa were proceeded. All the testa colors of F1
progenies from the reciprocal crosses were red. The segregated
ratio of F2 generation was 3 red：1 rose. These data derived
from proge
2.The reciprocal crosses of TN12 with slight reticulation of
pod and EG PN-18 with prominent reticulation were made. The F1
of reciprocal crosses showed moderate reticulation. The
segregated ratio of F2 generation was 1 slight：2 moderate：1
prominent. A
3.The reciprocal crosses of TN12 with 2-kernel and EG PN-18
with 3- or 4-kernel were made. Most of the F1 showed the
character of 2-kernel. The segregated ratio of F2 was 15
(2-kernel)：1 (3-kernel). The segregated ratio of F3 from F2 of
2-kernel was 7 (n
