Abstract EN
Brassica napus was synthesized by hybridization between its diploid progenitor species B.
rapa and B.
oleracea followed by chromosome doubling.
Cross with B.
rapa as a female parent was only successful.
Among three colchicine treatments (0.10, 0.15, and 0.20%), 0.15% gave the highest success (86%) of chromosome doubling in the hybrids (AC; 2n=19).
Synthetic B.
napus (AACC, 2n=38) was identified with bigger petals, fertile pollens and seed setting.
Synthetic B.
napus had increased growth over parents and exhibited wider ranges with higher coefficients of variations than parents for morphological and yield contributing characters, and yield per plant.
Siliqua length as well as beak length in synthetic B.
napus was longer than those of the parents.
Number of seeds per siliqua, 1000-seed weight and seed yield per plant in synthetic B.
napus were higher than those of the parents.
Although flowering time in synthetic B.
napus was earlier than both parents, however the days to maturity was little higher over early maturing B.
rapa parent.
The synthesized B.
napus has great potential to produce higher seed yield.
Further screening and evaluation is needed for selection of desirable genotypes having improved yield contributing characters and higher seed yield.
