There was a clear evidence of positive heterosis in plant height. The hybrids showed increase in plant height over the two parents. All the hybrids are significantly superior to both of the parents with respect to the total number of tillers produced. With regard to the number of nodes the hybrids did not show any significant difference over the parents. In the area of flag leaf the hybrids between Dee-Geo-Woo-Gen x Annapurna manifested positive heterosis while the reciprocal hybrids showed little heterosis. As regards the area of second leaf from the tip both the hybrids were not superior over the parents. But for the character of second leaf angle the hybrids were superior to their parents with reduced leaf angle. In general hybrids were better than the parents with respect to plant height, number of tillers, area of flag leaf and leaf angle.ennullArticle
