Abstract
Floral biology studies which were conducted for four characters (anther colour, anther size, anther length and style length) resulted in finding out the significant differences among sex-morphotypes (male fertile, partial male sterile and male sterile) of different lines. The differences were recorded in anther size and shape of anther. Anther length varied from 0.76 to 1.81 mm in three sex morphotypes. Breadth of anther varied from 1.19 to 1.73 mm. Size of seed varied from 2.43 to 2.73 mm in three sex morphotypes of different germplasm lines. Mean of style length was 5.12, 7.12 and 8.14 mm in fertile, partial male sterile and male sterile type respectively. It could be concluded that floral biological observation could be successfully utilized to characterize male sterility in P. ovata (Isabgol).
