    GENOTYPIC RESPONSE OF BITTER GOURD (Momordica charantia L.) TO DIFFERENT SEED PRIMING TREATMENTS
    (Punjab Agricultural University, Ludhiana, 2013) Rakesh Kumar
    The present investigation was conducted at Vegetable Research Farm of Department of Vegetable Science and Seed Technology Centre, PAU, Ludhiana during January-June 2012. The experiment was laid in split plot design keeping two environments (third week of January and third week of February) in main plot, five genotypes (Punjab 14, Punjab Kareli, Jaunpuri Long, Katahi and Green Special Long) in sub-plot and six treatments along with control (hydration, GA3, KNO3, KH2PO4, hydration + FYM for 1 day, hydration + FYM for 2 days) in sub-sub plot. The data was recorded on seed quality, vegetative and yield characters. Environment-2 was better in seed quality characters while environment-1 excelled in vegetative and yield characters. Among all genotypes, cultivar „Katahi‟ was most responsive to seed priming treatments in terms of seedling dry weight, root length, vigour index-II, field emergence (%), speed of emergence and number of fruits per plant followed by cultivar „Green Special Long‟ for germination (%), seedling length and vigour index-I. „Jaunpuri‟ Long exhibited improved speed of germination, minimum days taken to first female flowering, first fruit harvesting, average fruit weight and yield per plant. The statistical analysis of data showed the superiority of all the seed priming treatments over the control. The treatment GA₃ resulted in maximum germination (%), speed of germination, vigour index, field emergence (%), speed of emergence, vine length, number of fruits per plant and yield per plant in both the environments in all cultivars while highest seedling length, seedling dry weight, vigour index was recorded with seed treatment KH2PO4 in all the cultivars. Key words: Bitter gourd, genotypes, seed priming treatments, field emergence, speed of emergence, genotypes x environmental interaction

    COMPARATIVE PERFORMANCE OF F1 HYBRIDS OF BRINJAL UNDER NET-HOUSE AND OPEN FIELD CONDITIONS
    (Punjab Agricultural University, 2013) Harjinder Singh; Dhatt, A. S.
    The present evaluation was conducted in the Department of Vegetable Science, Punjab Agricultural University, Ludhiana, with a set of 40 different hybrids of brinjal (Solanum melongena L.) under net-house and open field conditions. The material was grown during the year 2012 in randomized complete block design. The analysis of variance showed significant difference among growing conditions and the hybrids. Out of 40 hybrids, BHO 1210 (2.92 kg), BHR 1209 (2.76 kg), BHR 1201 (3.03 kg), BHL 1242 (2.57 kg) and BHL 1244 (2.55 kg) gave significantly higher yield in net-house as well as the open field. Similarly, average fruit weight was also higher in BHR 1201, BHR 1220 and BHO 1209 in the both growing conditions. Maximum marketable yield was obtained from the hybrids BHO 1210 (3.47kg), BHR 1201 (3.08kg) and BHR 1220 (2.76kg) per plant in net-house. Out of these, the long fruited hybrids BHL 1242 (47 fruits/plant) and BHL 1241(37 fruits) gave high number of fruits under both the growing conditions. Observation recorded for biochemical analysis showed that maximum total sugars found in BHL 1244 (2.28%) under net-house and (2.11%) in open field. Maximum anthocyanin was found in hybrid BHO 1209 (1.90mg/100g) in net-house and (1.70mg/100g) in open field. There was no attack of fruit borer under the net house, whereas, 19.36 per cent infestation was recorded in the open field. Significant per se performance and economic heterosis in desirable direction was recorded in several hybrids under both conditions. Among round shape group BHR 1201 (37.99%); among long BHL 1241 (23.33%) and BHL 1242 (20.18%) and among oblong BHO 1209 (46.48%) and BHO 1210 (55.15%) were found significantly superior in heterosis over standard check (BH-2) for the yield per plant under the net-house. Thus, after further evaluation these hybrids can be recommended for net-house and open field cultivation.
