maternal plant

The differences of expression at different environments for triploid endosperm nuclear genes, cytoplasmic genes and diploid maternal plant nuclear genes were found for the performance of TR.

控制稻米透明度性状表现的三倍体胚乳核基因、细胞质基因和二倍体母体植株核基因效应在不同环境下存在着表达水平上的差异。

Triploid endosperm and diploid maternal plant genetic effects were the major effects at the early filling stage, and diploid maternal plant genetic effects were at the middle filling stage and direct dominance effect and maternal dominance effect were at late filling stage and mature period.

其中灌浆始期以三倍体种子和二倍体母体植株效应为主，灌浆中期以母体植株遗传效应为主，灌浆后期和成熟期以种子直接显性效应和母体植株显性效应为主。

Most characteristics of L_1 seed, plant and spike look like their paternal rye or present intermediate type, others like their maternal wheat. With the chromosome being doubled naturally, the diploid seeds, namely triticale are obtained from L_1 plants.

L＿1代种子、植株和穗的大多数形态特征呈中间型或似父本，其余特点象母本。在L＿1代植株中均获得了染色体自然加倍的双二倍体，即小黑麦种子。
