In view of the anticipated adverse impact of microclimatic conditions on ‘A’, ‘B’ and ‘R’ line of hybrid rice in West Bengal, a field experiment was conducted at the Teaching Farm, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India during kharif season 2012, boro season 2012-13, kharif season 2013 and boro season 2013-14 and quantify the impact of microclimatic conditions. The outcomes of the study have been found of utmost importance which would help in proper management of rice cultivation in West Bengal so as to minimize the adverse impact of microclimatic variation on synchronization of flowering and yield. Based on the mean GDD requirement for different phenophases of the parental lines, it was observed that GDD requirement for germination to panicle initiation was higher during kharif season than that of boro season. The lowest variation of GDD was revealed for germination to 100% flowering in both restorer and CMS line with co-efficient of variation 3.9 % and 7.6 % for restorer line and CMS line respectively. Similarly, HTU essentiality was higher in kharif season than that of boro season and co-efficient of variation was 28.4 % and 13.7 % in restorer and CMS line respectively. Whereas, germination to 50 % flowering higher co-efficient of variation was observed (47.8 % and 16.3 % in restorer and CMS line respectively). Similarly, there was difference between the kharif season and boro season in respect of PTU requirement for germination to 50 % flowering in both restorer and CMS line. Comparing the GDD, HTU and PTU trend it was noticed that GDD had minimum co-efficient of variation and thus, GDD was consistent parameter for predicting in flowering initiation of parental lines. The sowing dates should be chosen judiciously so that flowering may occur at the same time in both restorer and CMS line. It was recorded that GDD requirement of restorer line was 210-degree day higher than CMS line. Accordingly, the restorer line may be seeded at earlier date than CMS line.
