Abstract
A field experiment entitled “Evaluation of local genotypes in dolichos bean (Dolichos lablab L.)” at Chilli and Vegetable Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during kharif season of year 2018-19. with the objectives to collect the local genotypes of dolichos bean from Vidarbha region, to study the performance under Akola conditions and to find out the suitable genotype with better yield and quality of dolichos bean. There were twenty-eight genotypes of dolichos bean tested in the present study.
The experiment was conducted in Randomized Block Design (RBD) with three replications. At the time of experiment, the observations were recorded on the various parameters viz., vine length, primary branch per plant, days to flower initiation, flower colour, days to 50% flowering, days to first pod set, days to first harvest, yield of green pod per plant (kg), yield of green pod per hector (q/ha), protein content (%), fiber content (%), pod colour, pod length (cm), pod width (mm), weight of 10 green pods (g), pods per plant, crop duration, aphid infestation (%), pod borer (%), wilt (PDI) were recorded during the period of investigation
Highly significant differences were observed in the genotypes for all the characters under study. The genotype AK-WAL/18-07 showed maximum primary branches per plant (1.63, 5.97, 10.80, 14.53 and 17.67, respectively), at 30, 60, 90, 120 and 150 DAS respectively. The genotype AK-WAL/18-21 was expressed earliest (44.3) days to flower initiation, days to 50 % flowering (73.33), days to first pod set (91.10) and first harvest (101.33 days). Check variety dipali recorded maximum pod length (17.23 cm), and ten-pod weight (145.3 g). Pod width was noticed maximum (37.2 mm) in genotype AK-WAL/18-24. Number of pods per plant were ranged from 32.98 to 266. And the genotype AK-WAL/18-07 expressed maximum pods per plant as well as pod yield per plant (201.67 q). Six different pod-colors (cream with purple suture, light green, green, greenish purple, dark purple) were recorded as variability amongst genotypes under present study.
The genotypes AK-WAL/18-21, AK-WAL/18-15, AK-WAL/18-16 reported to be earlier genotype, which might be considered as best genotypes for short duration. The maximum (21.7 %) protein content was reported by genotype AK-WAL/18-13. Whereas, the (6.36 %) fiber content was observed in genotype AK-WAL/18-17.
As regards to the infestation by sucking pest to dolichos bean crop is concerned, genotypes AK-WAL/18-08, AK-WAL/18-09, AK-WAL/18-16, AK-WAL/18-17 showed resistivity against aphid. However, genotype AK-WAL/18-20 noticed susceptibility against aphid. The other important pest pod borer was noticed tolerance with genotype AK-WAL/18-05 and susceptibility with genotype AK-WAL/18-15.
Therefore, genotypes AK-WAL/18-06, AK-WAL/18-07, AK-WAL/18-15, AK-WAL/18-16, AK-WAL/18-17, AK-WAL/18-24 and AK-WAL/18-25 could be undertaken in further breeding programmes in order to improve the qualitative and quantitative features of existing cultivars in dolichos bean.
Description
The present experiment was carried out during kharif season of academic year 2018-19, at Instructional Farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The statistical design adopted for the experiment was Randomized Block Design (RBD) with three replications and twenty-eight treatments were tested for its growth, yield, quality and plant protection.
