Abstract

Biparental progenies (BIP's) of inter-varietal cross Mino Early White x Pusa Himani (MEW x PH) of radish were developed in F₂ generation by utilizing North Carolina Design-I suggested by Comstock and Robinson (1948 and 1952). The analysis of variance indicated significant differences among the BIP's and F₃ progenies for different horticultural and quality parameters studied indicating the presence of good quantum of variability between BIP's and F₃ progenies. Biparental progenies when compared with F₃ progenies for their overall mean values revealed that former had greater means for most of the characters except leaf weight, leaf length and nitrate content. The biparental progenies resulted in creation of more genetic variability by breakage of both coupling and repulsion phase linkages that conceal the genetic variability in F₂. The phenotypic variability as revealed by the coefficient of variation (%) was greater in BIP progenies than F₃ progenies. The superior performance of biparental and F₃ generations revealed the breakage of undesirable linkages and plateau effect for bringing further improvement in radish.

Abstract

Field experiment was conducted to study the effect of different seed priming treatments on yield and yield components of wheat (Triticum aestivum L.) under irrigated and rainfed conditions with cv. HPW 236 at CSKHPKV, Palampur, India during 2014-15. The experimental design was randomized complete block design (factorial) with four replications each under irrigated and rainfed situations. The first factor was situation i.e. irrigated and rainfed situation and the second factor was priming treatments viz., unprimed seed (control), tap water, KNO₃(2.5%), KCl (2.0%) and KH₂PO₄(1.0%). Results showed that situation and priming treatments significantly reduced the days to 75 per cent field emergence, days to 75 per cent flowering, days to maturity, increased the plant height (cm), leaf area (cm²), spike length, number of tillers per plant, number of spikes per plant, number of spikelets per spike, number of grains per spike, 1000-grain weight, seed recovery percentage, straw yield and seed yield. Results of the experiment showed that seed priming with KNO (2.5 %) and water for 16 hours 3 significantly increased seed germination, seed yield and yield components of wheat under both irrigated and rainfed situations.

Abstract

A field experiment was conducted at Palampur during kharif 2015 to study the effect of different seed coating treatments on seed yield and related parameters in quality protein maize hybrid HQPM 1. The seeds were coated with polymer, fungicides, insecticide, polymer-fungicides and polymer-insecticide combinations. Seed coating had significant effect on days to 50% tasseUng, days to 50 % silking, days to 75 % maturity, plant height (cm), cobs per plant, cob length (cm), cob girth (cm), number of rows per cob, number of seeds per row, seeds per cob, 100-seed weight (g) and seed yield (q/ ha). Seed coating with polymer+ vitavax 200* @ 2 g/kg of seed and vitavax 200* @ 2 g/kg of seed recorded significantly higher seed yield (q/ha), plant height (cm), cobs per plant, cob length (cm), cob girth (cm), number of rows per cob, number of seeds per row, seeds per cob and 100-seed weight (g) in comparison to the untreated control.

Abstract

A field experiment was conducted at Experimental Farm of Seed Science and Technology, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur during Kharif 2014 to study the effect of seed coating with synthetic polymer and additives on growth parameters and seed yield of soybean (Glycine max (L.) Merrill.] cv. Hara soya. The seeds were coated with 7 different treatments of polymer, fungicides, insecticide, polymer-fungicides and polymer-insecticide combinations. Seed coating exhibited significant effect on plant height (cm), branches per plant, pods per plant, empty pods per plant, pod length (cm), seeds per pod, 100-seed weight, seeds per plant and seed yield (q/ha). Amongst various coating treatments, seed coated with polymer @ 3.0 ml per kg of seed and flowable thiram @ 2.4 ml per kg of seed (T₃) recorded highest pods per plant (71), pod length (4.30 cm), seeds per plant (162), 100-seed weight (18.40) and seed yield (25 q/ha) as compared to untreated control (T_o).
