    The present study entitled “Effect of NPK, Biofertilizers and Biostimulants on growth, flowering, seed yield and quality of China aster (Callistephus chinensis L.) Cv. Arka Kamini” was carried at Floricultural Research Station, (Agricultural Research Institute) Rajendranagar, Hyderabad during November to April 2020- 2021. The experiment was laid out in Completely Randomized Design with three replications and seven treatments viz., T1 - RDF 100 %, T2 - RDF 75 % + Azotobacter + PSB + KSB, T3 - RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %), T4 - RDF 75 % + Azotobacter + PSB + KSB + Humic acid (0.5 %), T5 - RDF 50 % + Azotobacter + PSB + KSB, T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) and T7 - RDF 50 % + Azotobacter + PSB + KSB + Humic acid (0.5 %). The study revealed that significant differences were recorded in China aster. Among the growth parameters, maximum plant height (8.27, 23.56 and 32.27 cm) at 30, 60 and 90 DAT were noticed in T6 i.e., RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %). Maximum number of branches per plant (6.20 and 23.96) at 30 and 90 DAT was recorded in T7 i.e., RDF 50 % + Azotobacter + PSB + KSB + Humic acid (0.5 %) and (12.22) at 60 DAT was observed in T3- RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) Among different flowering parameters T3- RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded least number of days taken for flower bud initiation (50.64 days), minimum number of days taken for bud opening (18.33 days), minimum number of days for 50 % flowering (60.97 days) and maximum duration of flowering (48.37 days). Among different treatment combinations T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded maximum flower diameter (5.53 cm). Whereas, T3 - RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded maximum flower longevity on plant (15.22 days), maximum number of flowers per plant (21.98) and maximum flower yield per plant (50.16 g). The application of RDF 75% + Azotobacter + PSB + KSB + Seaweed extract (0.5%) (T3) recorded highest seed yield per flower (0.30 g), seed yield per plant (6.59), number of seeds per gram (484.00 g) and test weight (1.72). Further, maximum germination percentage (90.00 %), seedling length (5.93 cm) and seedling vigour index (534.67) was recorded in T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %). The highest available nitrogen (208.33 kg/ha) phosphorus (57.91 kg/ha) and potassium (162.56 kg/ha) in soil was recorded by the application of RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) (T3) The data on the economics of effect of NPK, Biofertilizers and Biostimulants on China aster revealed that, T3 - RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded the highest benefit cost ratio (2.37) over other treatments. It can be concluded that, T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) proved to be the best treatment compared to other treatments to improve plant height, flower quality and yield parameters and seed quality parameters of China aster. While, T3 i.e., RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) was found to be the best treatment to improve flowering parameters, seed parameters and soil nutrient status of China aster

    (COLLEHE OF HORITCULTURE, MOJERLA, 2022-03-24) GUGULOTHU SURESH; Dr.N.SREENIVASAN; Dr.J.Srinivas; Dr.B.SAI KRISHNA NIKHIL
    The investigation entitled “Genetic Variability and Divergence studies in Ridge Gourd (Luffa acutangula L.) genotypes” was carried to estimate the genetic divergence, genetic variability, correlation and path analysis for yield and yield components of ridge gourd genotypes. Twenty four genotypes were sown in a Randomized Block Design with three replications to evaluate genetic divergence at College of Horticulture, Mojerla, Wanaparthy, during Rabi, 2021. The data on analysis of variance (ANOVA) for yield and yield contributing characters under study revealed that there was significant amount of variation among genotypes for all the sixteen characters studied. Wide range of variability was observed for number of leaves per vine (700.51) followed by average fruit weight (643.33) and days to first appearance of male flower (12.27) indicating the scope for selection of initial breeding material for further improvement. The results of mean performance of twenty four genotypes for sixteen characters revealed that the genotype IC - 279347 found to be the superior for yield and yield contributing characters i.e., fruit yield per vine (1956.48), number of fruits per vine (4.44 g) and average fruit weight (146.88). The genotype IC - 341099 found to be significantly superior for number of primary branches (15.778). The genotype IC - 262128 recorded more number of leaves per vine (120.55). The genotype IC - 279347 was found to be superior for leaf width. Highest internodal length was found in genotype IC - 264908 (21.23). Mahalanobis D2 statistical analysis classified twenty four genotypes into five clusters and revealed that fruit yield per vine (14.32%) contributed maximum towards divergence followed by number of fruits per vine (13.45%), fruit diameter (11.50%), node number for first female flower appearance (9.78%), fruit length (8.90%), sex ratio (8.21%), node number for first male flower appearance (7.00%), average fruit weight (6.50%), days to first female flower appearance (4.00%), internodal length (3.00%), number of leaves per vine (2.00%), days to first male flower appearance (2.00%), number of primary branches (1.09%), leaf width (1.00%), and leaf length (0.36%). The inter cluster D2 value revealed that the highest inter cluster generalized distance (522.87) was between cluster IV and V while the lowest (13.56) was between cluster II and IV. The genotypes of clusters showing high genetic divergence could be effectively utilized in heterosis breeding programme. High heritability coupled with high genetic advance as per cent of mean indicates operation of additive gene action which was observed in characters viz., number of leaves per vine, average fruit weight. From correlation studies, fruit yield per vine exhibited high significant positive association with vine length, number of primary branches, internodal length, number of leaves per vine, leaf length, node number for first male flower appearance, node number for first female flower appearance, days to first male flower appearance, days to first female flower appearance, sex ratio, number of fruits per vine, average fruit weight, fruit length and diameter indicating the importance of these traits in selection for yield. These characters should form selection criterion in breeding programmes. Direct selection based on these traits could result in simultaneous improvement of traits and bulb yield in ridge gourd. The path coefficient analysis in the study revealed the improvement of yield by improving the characters i.e., vine length, number of primary branches, internodal length, leaf length, days to first male flower appearance, sex ratio, number of fruits per vine, average fruit weight, fruit length and fruit diameter, the genotypes exhibited the genotypes which exhibited better performance for these characters can be used in further improvement of ridge gourd. Considering the mean performance, five superior genotypes viz., IC 279347, IC- 262128, IC- 355974 and IC-355959 with high yield and quality components may be utilized as parents in further improvement studies through various breeding strategies and after multilocation, multiseasonal studies may be released.

However, the same treatment recorded minimum days taken for initiation of germination, leaf emergence of rootstock and days taken for scion budbreak of graft. Among the sea weed extract treatments, the maximum germination percentage, plant height 30, 60 and 90 days, stem girth at 30, 60 and 90 days, number of leaves 30, 60 and 90 days, leaf area, root length, root: shoot ratio of rootstock ,graft take percentage, scion length at 30, 60 and 90 days, scion girth of scion at 30, 60 and 90 days, root length of graft, Leaf nitrogen, leaf phosphorous, leaf potassium was recorded in SWE at 8 ml.plant-1 compared to control. However, the same treatment recorded minimum days taken for initiation of germination, leaf emergence of rootstock and days taken for scion budbreak of graft. In combination of different potting mixture and sea weed extract studied, the maximum germination percentage (74.00 %), plant height at 60days (44.34 cm), at 90 days (51.85 cm), stem girth at 30 days (4.62 mm), at 60 days (6.86 mm), at 90 days (7.12 mm), number of leaves at 30 days (9.60), at 60 days (17.26), at 90 days (20.63), leaf area (93.24 cm2), root length (34.57 cm), root: shoot ratio (0.54) of rootstock and graft take percentage, scion length at 30 days (6.37 cm), at 60 days (8.32 cm), at 90 days (9.67 cm), scion girth of scion at 30 days (3.54 mm), at 90 days (5.67 mm), root length of graft (40.72 cm), Leaf nitrogen (4.86), leaf phosphorous (0.51), leaf potassium (5.37) was recorded in soil + vermicompost + cocopeat (2: 1: ½) in combination with sea weed extract at 8 ml. Plant-1. However, same treatment recorded the minimum days taken for leaf emergence of rootstock (14.00 days) and days taken for scion budbreak (8.33 days) of graft. The difference in growth parameters of mango rootstock and grafted seedling may be due to the high N, P, K content in seaweed extract, which increased the shoot and root growth of mango rootstock and graft cv. Banganpalli.

    STABILITY ANALYSIS OF YIELD, YIELD ATTRIBUTING TRAITS AND MOLECULAR PROFILING OF PROMISING GENOTYPES OF CLUSTER BEAN (Cyamopsis tetragonoloba L.Taub.)
    (Sri Konda Laxman Telangana State Horticulture University, Mulugu, Siddipet (Dist.), College of Horticulture, Rajendranagar, Hyderabad-30, 2020-10-01) RACHAMALLA RAVI TEJA; Dr. P. SAIDAIAH
    A field investigation entitled “STABILITY ANALYSIS OF YIELD, YIELD ATTRIBUTING TRAITS AND MOLECULAR PROFILING OF PROMISING GENOTYPES OF CLUSTER BEAN (Cyamopsis tetragonoloba L. Taub.)” was carried out in 25 genotypes for 17 yield and yield attributing traits in three environments for estimation of stability parameters using Eberhart and Russell model (1966) of phenotypic stability and genetic variability and molecular marker based genotyping was also studied. Twenty five genotypes of cluster bean including one check were evaluated in Randomized Block Design with three replications during Kharif, 2019 at three locations representing three agroclimatic Zones of Telangana i.e., PG Research Block, College of Horticulture, Rajendranagar, Hyderabad (Southern Telangana Zone), JVR Horticultural Research Station, Malyal, Mahabubabad (Central Telangana Zone) and progressive farmers field at Vemulawada, Karimanagar (Northern Telangana Zone). The main objective of the experiment was to identify stable genotypes to release as a varieties for commercial cultivation. The Analysis of Variance revealed significant differences between genotypes indicating presence of sufficient amount of variability in all the 17 characters studied. Wide range of variability was observed for pod yield per plant (4292.5), plant height (1613.3) and number of pods per plant (1054.43) indicating the scope for selection of initial breeding material for further improvement based on these characters. On the basis of mean performance over three locations, genotype i.e., IC-103295 was found superior over the check variety Pusa Navabahar for pod yield per plant (187g), followed by IC-9052 (157.06 g) and IC-34344 (131.61 g). Same genotype also registered superior number of branches per plant (9.3), number of pods per plant (103.15), plant height (119.744 cm) and number of clusters per plant (18.47) over the check variety Pusa Navbahar. Based on the environmental index, Hyderabad location was found to be favourable for plant height, number of branches per plant, number of clusters per plant, number of pods per plant, days to maturity, pod length, pod girth, pod weight, number of seeds per pod, pod yield per plant, pod yield per hectare, protein content and gum content. Karimnagar location was found favorable for plant spread, number of branches per plant, days to first flowering, number of clusters per plant and pod length. Malyal location was found favourable for plant spread, days to first flowering, days to first flowering and fibre content. Three cluster bean genotypes viz., IC-103295 (33.02 %), IC-10323 (32.46%) and IC-9077P1 (32.07%) exhibited significantly highest gum content compared with check variety Pusa Navbahar (28.1%). The promising genotype IC-103295 had average stability for number of branches per plant, days to first flowering, pod yield per hectare, pod girth, pod length, number of seeds per pod, number of pods per plant, pod yield per plant, protein content and gum content but showed below average stability for plant spread and above average stability for pod weight and number of clusters per plant. Genotype IC-200680 showed average stability for number of seeds per pod, pod yield per plant, pod yield per hectare and number of clusters per plant. The genotype IC-9052 showed average stability for days to 50 % flowering, number of clusters per plant, number of seeds per pod, pod yield per plant, pod weight, number of pods per plant and pod yield per hectare but below average stability for fibre content and number of branches per plant and above average stability for number of pods per cluster. Genotype IC-10323 showed average stability for number of seeds per pod, pod yield per plant, pod yield per hectare, number of clusters per plant and days to maturity. Genotypes IC-9052, IC-10323, IC-10333, IC-103295 and IC-200680 were high yielding and stable under all environments were categorized under group-I. While genotypes IC-177844 and IC-140774 were high yielding and suitable to favourable environments were categorized under group-II. IC-140777 exhibited high yielding and suitable to unfavourable environments were categorized under group-III. Genotypes IC-34344 and IC-39989 high yielding and unstable were categorized under group-IV. GA as per cent of mean, GCV and PCV values were at par with each other for most of the characters which indicated that the influence of the environment on the trait (s) was very negligible. The recorded values were not influenced by the environment. It is a true reflection of the homeostasis effect or buffer reaction of the gene. Thus, the true reflection of the trait is exhibited. A true agreement with the GCV and PCV values in the present investigation for the 17 characters was noticed, indicating additive genetic variance governing the high heritability with high genetic advance as per cent of mean. Thus, a breeder can employ a simple selection process which will be a rewarding one to improve the characters viz., plant height, number of branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length, pod girth, pod weight, number of seeds per pod, pod yield per plant, pod yield per hectare, protein content, gum content and fibre content. High heritability coupled with moderate genetic advance as per cent of mean observed for days to first flowering and days to 50 per cent flowering. Out of 30 markers, used in the investigation all the markers produced a clear and good amplification which can be score and used for analysis. 100% polymorphism was attained across the genotypes with total 1756 amplicons. Among these, OPL-5 was highest with outcome of 100 amplicons, OPA-9 and OPS-4 followed with 84 and 83 amplicons respectively. The highest number of 100 bands with 6 alleles was amplified with OPL-5, followed by OPA-9 and OPS- 4 with 5 alleles each and the least number of 28 bands with OPB-10 yielded 2 alleles. High PIC value was observed for markers i.e. OPH-2(0.728) followed by OPA-7 (0.718). Low PIC value was observed for OPC-8 (0.3228). On the basis of mean performance of the genotypes for all the traits studied, four genotypes viz., IC-103295 (187 g), IC-9052 (157.06 g), IC-200680 (146.6 g) and IC-10323 (137.15 g) were identified as promising for yield per plant and stable when compared to check variety Pusa Navbahar (106.8 g). The selected germplasm can be use as parental source for the development of superior cluster bean varieties for commercial cultivation. They are also recorded clear molecular divergence.
