RÉSUMÉ
An investigation consisted of 50 chickpea genotypes including 4 checks viz., JG64, ICC10685, ICC4567 and NBeG47 was conducted during the rabi season of year 2022-23 at Seed Research and Technology centre, Rajendranagar, Telangana. The objective of the study was to estimate magnitude of different parameters of genetic variability for yield and its attributes. The observations were recorded for thirteen different yield and its contributing characters and the results obtained indicated that in general the phenotypic coefficient of variance was found to be higher as compared to genotypic coefficient of variance for all studied traits. High heritability along with high genetic advance (% mean) was obtained for characters like number of seeds per plant, number of filled pods per plant, seed yield per plant, number of pods per plant, number of primary branches, 100 seed weight, number of secondary branches, and plant height at normal sown conditions, which determines the presence of additive gene action for these characters and in late sown conditions the characters like number of seeds per plant, number of filled pods per plant, seed yield per plant, number of pods per plant, number of primary branches, 100 seed weight, number of secondary branches, and plant height and harvest index had shown high heritability along with high genetic advance. So, it determines the presence of additive gene action for these characters. So, that selection for these characters is beneficial in the breeding programmes.
RÉSUMÉ
The soybean seed (JS 335) was collected from 8 different seed production locations in Telangana state and were treated with different seed treatment chemicals. The seed quality parameters of soybean seed kept at ambient conditions in gunny bag were recorded at monthly intervals during storage. The results revealed that, among the various seed treatments chemicals, the seeds treated with Xelora (Thiophanate Methyl 45% + Pyraclostrobin 5% FS) @ 2 g kg-1 recorded significantly high seed quality parameters viz., seed germination per cent, seedling vigour index-II, field emergence, moisture per cent, seed infection per cent and low electrical conductivity compared to all other treatments. Among the seeds collected from different seed production locations the seed collected from Nirmal location had shown better seed quality parameters.
RÉSUMÉ
Poor germination in fodder crops is one of the major reasons responsible for lower than potential green forage yield of cereals. Invigoration treatments aids to promote and accelerate germination, increase the vigour of seedlings, and improve stand establishment in field, vegetable, and horticultural crops. Therefore, a study was carried out to evaluate the effect of different seed invigoration treatments on seed quality parameters viz., germination, field emergence, speed of germination, seedling length, dry weight and seedling vigour in fodder maize (Zea mays L.). The experiment was laid out in factorial completely randomized design with two factors i.e., months and treatments having 5 different seed priming treatment combinations i.e., - Priming with water for 12 hrs., - Priming with NaCl @ 4 g / litre of water for 8 hours., - Priming with Poly Ethylene Glycol solution @ 10g / litre of water for 8 hours., – Priming with GA3 @ 0.2 g / litre of water for 8 hours and - Control (unprimed seeds) and the treatments were replicated four times during Rabi, 2022-23 at the Department of Seed Science and Technology, Seed Research and Technology Centre, College of Agriculture, PJTSAU, Rajendranagar, Hyderabad, Telangana. The results obtained from this study indicate that hormonal priming with GA3 can be successfully employed to improve germination, field emergence, seedling length, dry weight, and seedling vigour in fodder maize (Zea mays L.). At the end of the study, it was observed that hormonal priming with GA3 had a significantly positive influence on mean germination per cent (90%), field emergence (87%), speed of germination (20.221%), seedling length (34.17 cm), dry weight (0.792 g), seedling vigour index-I (3082.05) and seedling vigour index-II (71.42) over the control.
