Abstract: Kanamycin sensitivity studies were conducted to study the resistance level of kanamycin in cauliflower (Brassica oleracea var. botrytis, cv. Pusa Snow Ball). Increasing doses of kanamycin (10, 20, 30, 40, 50 mg/litre) were given to hypocotyl and cotyledon explants to determine a minimum concentration of kanamycin required for selection of putative transformed cells during transformation. Decreases in fresh weight in both cotyledon and hypocotyl tissues were observed with increasing in kanamycin concentration. Even 50 mg/litre kanamycin did not completely inhibit the growth but callus formation and shoot regeneration was affected. It is suggested that at least 20-30 mg/litre kanamycin would be necessary to select resistant transformants in callus and shoot cultures.

Abstract: Complete removal of leaves, along with decapitation of shoots, promoted flower bud differentiation (FBD), while ringing with partial or complete defoliation along with decapitation of shoots did not promote FBD. Decapitation of leafy shoots also promoted FBD, increasing from 44 to 63% and 37 to 54% in Sardar and Allahabad Safeda, respectively. Defoliation of same age shoots (1-3 months old) at different times of the year influenced FBD. In many cases, defoliation did not promote flowering compared with controls. Principal component analysis revealed that the time of shoot emergence was the decisive factor for FBD in 1-, 2- and 3-month-old shoots. Defoliated shoots put forth terminal extension or axillary growth, while in undefoliated ones only terminal growth took place. There is a strong indication that in guava, leaves play a favourable role in flower bud formation.

Abstract: Nine mango [Mangifera indica] genotypes having dwarf stature were compared to the control Alphonso for morphological and fruit characteristics, in order to identify those with potential for use in breeding programmes. Varieties Kerala Dwarf and Janardhan Pasand were the most suitable for usage as donor parents.

Abstract: A survey of bael (Aegle marmelos), jamun (Syzygiumcumini), mahua (Bassia latifolia [Madhuca longifolia]), lasora (Cordia myxa), wood apple (Feronia limonia [Limonia acidissima]), monkey jack (Artocarpus lakoocha [A. lakucha]) and karonda (Carissa carandas) growing regions, particularly in eastern Uttar Pradesh, was conducted to examine the variability in existing germplasm for selection of desirable genotypes. Information was recorded on fruit physical and chemical characteristics, and much variability was observed. Some desirable traits were identified.
