| 1 | Expression of Heterosis for Productive Traits in Bottle Gourd Hybrids显示文摘An intensive study was conducted in bottle gourd to assessment the magnitude of heterosis for yield and its thirteen yield related traits.Twenty one bottle gourd hybrids generated from 7×7 diallel cross(excluding reciprocals)along with their seven parents evaluated in a RCBD with three replication at the Olericulture Division of Horticulture Research Centre,BARI,Gazipur,Bangladesh during 2018-19.Maximun cross combinations were found significant heterobeltiosis for earliness.The maximum heterobeltiotic effect was observed in P2XP7 and P4XP7.The best heterotic cross for fruit length was P4XP5.Maximum heterotic effect in respect of fruit number per plant was found in the cross P1XP6 and P4XP6.In terms of yield the highest heterobeltiosis was shown by the crosses P3XP4,P3XP5,P4XP5 and P4XP7.In the overall analysis,both additive and non-additive gene actions were found important with predominance of the additive gene effects in the inheritance of bottle gourd. | AKM Quamruzzaman M.M.R.Salim L.Akhter M.M.Rahman M.A.Z.Chowdhury | 2020 | Journal of Botanical Research2020，2，2： | 0 |
