Abstract

Leonurus sibiricus is an annual herb belongs to the mint family Lamiaceae. There are two varieties namely, Leonurus sibiricus L. and Leonurus sibiricus var. albiflorus Migo. The two varieties are hard to be distinguished based on vegetative characters but can be clearly differentiated based on the colour of flower. However, 8 vegetative characters had been determined which showed that L. sibiricus var. albWorus is more vigorous compared to L. sibiricus. The flower development of the two varieties was described and used as reference for the pollination study. Pollination study showed that, the two varieties are self-pollinated plant. However they can be artificially cross-pollinated. The seeds resulted from cross-pollination were germinated to produce F, progenies. The successful hybrids are to be named as L. sibiricus var. albforus {o+} Migo x L. sibiricus {o! } L. and L. sibiricus {o+} L. x L. sibiricus var. albforus{o! } Migo. The flavonoid inheritance pattern was studied for the F, progenies. Spot 1,2 and 4 specifically found only in L. sibiricus. Whereas Spot 3,5,6, and 7 were shared between the two varieties. Referring to the flavonoid data of all the F, progenies resulted from cross and reciprocal cross, those resulted from the cross of L. sibiricus as pollen donor while L. sibiricus var. albforus as female, inherited Spot 5,6, and 7 while the reciprocal cross resulted progenies inherited spot 3,5,6, and 7. It revealed that, the flavonoid inherited by the F, progenies was similar to those L. sibiricus var. albjorus.
