Generation mean analysis of yield and quality traits in carrot (Daucus carota L.)
Carrot is important root vegetable being used as raw and cooked form (gajar halwa). The root is main edible part, breeding should be focus on traits that can increase root production. The productivity of carrot depends upon the cultivar and its yield contributing characters. Information of the genetics analysis of yield traits is essential for developing new breeding lines which can contribute to improvement of specific traits. The production should be based on yield contributing traits like plant height, number of leaves, leaf length, root length, root diameter, core diameter, root weight, TSS, yield per plant, root fresh weight and root dry weight. As a result, the findings aid in the production of carrot hybrids or cultivars. Genetic analysis of yield traits of carrot was estimated through three cross combinations, and the results revealed the existence of additive [d], dominance [h], additive x additive [i], additive x dominance [j] and dominance x dominance [l] gene actions. In most cases, duplicate epistasis was seen for traits such as plant height, number of leaves, leaf length, core diameter, TSS, root fresh weight, and root dry weight. The presence of additive, dominance, additive, and dominance interaction effects was indicated by similar signs of (h) and (l) for the expression of root length, root diameter, root weight, and yield per plant, indicating the presence of additive, dominance, additive, and dominance interaction effects. The complementary type showed that these traits might have a significant degree of heterosis, and that recurrent selection could be employed to improve these traits in future generations.
Propagation Studies in Jamun [Syzygium cumini (L.) Skeels] under Rainfed Conditions
Investigation on propagation of jamun under rainfed conditions of Jammu sub-tropics was carried out in the year 2019-20, with four different methods i.e. T-budding, patch budding, tongue grafting and wedge grafting during three different timings viz. 4th week of July, 2nd week of August and 4th week of August under open field conditions. The results of the study indicated that among various methods and different timings of propagation, significantly minimum days taken to bud sprouting (16.45 days) were observed in wedge grafting performed during 4th week of July. Whereas, higher length in scion wood (39.90 cm), per cent sprouting (64.00 %) and success (59.66 %) was observed in wedge grafting during 2nd week of August. After 180 days of jamun propagation, maximum number of shoots (9.47) shoot length (49.68 cm), average leaf area (20.76 cm2) and plant height (89.70 cm) were recorded in wedge grafting performed during 2nd week of August, while, maximum stock-scion ratio was observed as 1.95 in patch budding performed during 2nd week of August.
Organic amendments and nitrogen levels effects on soil health and productivity of rice-wheat cropping system in North western India
Soil fertility is at risk in intensive cropping systems when using an exclusive regime of inorganic fertilisers without returning sufficient organic matter to the soil. Our objective was to evaluate the effects of organic amendments interacting with different rates of inorganic nitrogen fertiliser on crop yields of rice and wheat. Yield data from rice and wheat were collected for two seasons between 2018 and 2020 from a continuous field trial based at PAU, Ludhiana and Research station, Dyal Bharang, Amritsar in split plot design. Main plot consisted of four treatments (green manuring, farmyard manure, poultry manure and control) and four subplot treatments (Control, 50 kg N ha-1,75 kg N ha-1 and 100 kg N ha-1) replicated four times in rice crop and its residual effect was studied in wheat. Results revealed that rice-wheat productivity, plant growth, yield attributes and soil nutrients availability increased significantly (p<0.05) with the application of organic amendments at different nitrogen levels. Application of poultry manure in rice helped to increase grain yield over the other amendments and recorded 67.3 % and 61.4 % higher grain yield than control in both the years. The residual effect of poultry manure was also evident in subsequent wheat crop. It could be concluded that application of poultry manure along with 100 kg N ha-1 or 75 kg N ha-1 recorded similar yield, it implies that even lower dose could be sufficient for rice crop as well as following wheat crop to obtain higher yield.
Studies on response to day length extension on growth and flowering in spray chrysanthemum (Chrysanthemum morifolium Ramat).
This research were conducted to study the effect of different photoperiod in chrysanthemum cv. Autumn white and Diana orange for the period of 1st October 2021 to 20th March 2023 in climate controlled greenhouse at Centre for Protected Cultivation Technology (CPCT), IARI, New Delhi. Two spray Chrysanthemum varieties such as Autumn white and Diana Orange was exposed to 3 various day length extension treatments under semi climate controlled green house with use of Incandescent lamps for 10, 15 and 20 days duration and each 4 replications. Various observation in respect to growth and flowering were recorded at different intervals (0,15, 30,45 and 60 days). Vegetative growth parameters like plant height (95.79 cm), stem diameter (6.56 mm), inter nodal length (4.41cm), total number of leaves (39), leaf area (262.52 cm2), leaf area index(3.22), leaf fresh (24.91g) and dry weight(2.61 g), stem fresh (21.88g) and dry weight (3.23g) were measured and maximum under 20 days extended day length at 60 days after planting. Flowering parameters like bud diameter (16.78 mm), flower diameter (87.68 mm), time taken for flower bud induction(89.3days), time taken for flower opening (100.7 days), flower fresh(13.57g) and dry weight (1.59g) were taken at different blooming time intervals and highest were found in Autumn white at 60 days after planting for 20 days. Among two different varieties Autumn white showed significant difference than Diana orange.
OCCURRENCE AND CHARACTERIZATION OF XANTHOMONAS ORYZAE PV. ORYZAE, CAUSING BACTERIAL BLIGHT OF RICE IN TAMIL NADU
In the present investigation, an extensive survey was conducted to assess the severity and occurrence of bacterial blight disease from diverse rice ecosystems of Tamil Nadu during the Rabi and Kharif seasons of 2021-2022. The result showed that the Coimbatore district recorded the highest disease severity with a 70.26 Percent Disease Index (PDI) and the lowest severity in the Theni district (28.43%.). The morphological studies revealed that 25/40 Xoo isolates possess a short rod, with rounded ends, single or in pairs, yellow, circular, convex, slightly raised, motile with a single polar flagellum, capsulate and non-spore-forming. Biochemical tests viz., Gram staining, KOH test, Catalyst test, Citrate utilization, and Tween 80 hydrolysis showed a positive result for all the 25 Xoo isolates. To determine the pathogenic ability and virulence of Xoo isolates, a pathogenicity test was conducted under glasshouse conditions in BB susceptible variety TN1. The result indicated that all the 25 Xoo isolates exhibited susceptible reactions in TN1 with the average lesion length varying from 10.75 to 22.11 cm. Among that, the isolate Xoo12 (Coimbatore) exhibited high susceptibility with a lesion length of 22.11 ± 0.17 cm after the 14th day of inoculation and we considered this isolate Xoo12 as a virulent (TXO01 Strain). Meanwhile, the taxonomic identity of 25 isolates was confirmed as Xoo by using a PCR-based assay with the expected amplicon of 331bp and 162bp in Xoo specific primer.
