Cotton is king of fibre crops and has economic importance worldwide and new cultivars have to be released continuously to meet the demanding needs of economic market. To meet our requirement broad genetic base is needed which is limited due to continuous usage of common parents for crossing. So the germplasm, advanced breeding lines are to be characterised for variable characters. DUS characters listed by PPV FRA, New Delhi were used for this purpose. The field studies were carried out during kharif 2017-18 at RARS, Lam.

Anthocyanins are the primary source of colour in flowers and also accumulate in vegetative tissues, where they have multiple protective roles traditionally attributed to early compounds of the metabolic pathway (flavonols, flavones, etc.).

Oenothera biennis L., commonly known as Evening Primrose as flowers open in the evening. Inflorescence is racemose (spike) and flowering continues for about 3 months. Circular floral nectary of translucent colour are present at the point of attachment of petals and hypanthium. Pollen are triporate, of variable sizes held together by viscin threads. Sepals colour change from green to yellowish green, act as indicator of anther dehiscene in the morning in closed conditions and anthesis in the evening.

Investigations aiming at genetic improvement in Adenium obesum, a popular flowering pot plant were carried out at Advance Technology Centre of soilless system, department of Floriculture and Landscape Architecture, NAU, Navsari. Hybridization was initiated with ten parents (seven females and three males) in 2014 and their crosses were studied during 2015 to 2016. Among the crosses studied, a germplasm viz., SDSH1 (Sudarshan x Double Sweet Heart) showed novel morphological character for multipetalous form having attractive bright red coloured fifteen petals.
