Distant hybridization of cereals is often impaired by fertilization barriers. Haploid induction
through intergeneric crossing is well developed in wheat but has not been successful in rice …

Cross-incompatibility caused by endosperm abortion was found in advanced generations of
backcrossing between the Asian wild (W593) and cultivated (T65 wx) rice strains. The near …

Natural interspecific hybridization has been proposed to account for morphological variation
in the annual members of the genus Zizania, commonly known as wild-rice, although …

There is an urgent need for germplasm enhancement in rice to improve yield, quality, and
adaptability to diverse environments. One promising approach is to exploit heterosis and …

Meiotic disturbances in F 1 hybrids and their progenies are still major problems in wide
hybridization. To investigate the genome affinity reflected in chromosome pairing and …

Post‐pollination competition is reported here in cultivated rice (Oryza sativa) and a perennial
wild rice (O. rufipogon) to investigate the occurrence of crop‐to‐wild gene flow.• Wild and …

Background Inter-specific hybridization occurs frequently in plants, which may induce
genetic and epigenetic instabilities in the resultant hybrids, allopolyploids and …

Distant hybridization in the genus Oryza is realized as an efficient Biotechnological tool for
plant breeding work to introgress useful gene/s from diverse array of wild relatives into …

A post‐zygotic hybridization barrier is often observed in the endosperm of seeds produced
by interspecific or interploidy crosses. In A rabidopsis thaliana, for example, hybrid …

ABSTRACT A study was conducted during dry season of 1995, wet seasons of 1995 and
1996 at Cuttack and New Delhi to identify improved sou; ce of wide compatibility gene and …
