Genetics of quantitative and qualitative traits of isabgol (Plantago ovata)

N. Singh and Lal, R. K., Genetics of quantitative and qualitative traits of isabgol (Plantago ovata), vol. 8, pp. 939-950, 2009.

Isabgol is a medicinal plant known for its high-quality dietary fiber. The genetics and inheritance of economic characters, such as number of panicles, panicle length, seed yield, and swelling factor, were measured by diallel analysis of F1 progenies from seven parents. The additive component of genetic variance was significant for days to flowering, plant height, branches/plant, peduncle length, panicle length, days to maturity, and swelling factor, whereas the dominance component of genetic variance was significant for all the characters except panicles/plant.
