“…In this study seed yield was positively correlated with seed number per pod, seed number per plant and pod weight whereas pod bearing was negatively associated with hundred seed weight. The positive correlations of various traits in this study shows the usefulness of the traits for selection in crop improvement and they can further be used for improvement of seed yield [33,34]. Similar trends were reported by Sodavadiya et al [35] and Linge et al [36] and Prasad et al [37] in pigeon pea studies.…”

Pigeon pea is one of the most important leguminous crop globally. However it is a neglected pulse crops in South Africa in terms of research and production. Most farmers grow local landraces with low yields and there is lack of diverse material. The objective of the study was to determine the presence of genetic diversity among the pigeon pea genotypes using quantitative and qualitative phenotypic traits. The trials were conducted in Mafikeng and Nelspruit in South Africa. The trials were laid out in randomised complete block designs replicated three times. The quantitative and qualitative phenotypic data were recorded according to pigeon pea descriptor list. The phenotypic data were analysed using analysis of variance, Pearson’s correlations, principal component analysis, and biplots constructed using principal coordinate analysis, Shannon weaver diversity indices and frequencies. The results showed highly significant differences among the genotypes based on plant height, pod bearing and seed number per pod meaning there was vast genetic diversity among the genotypes. Seed yield was positively correlated with seed number per pod, seed number per plant and pod weight whereas pod bearing was negatively associated with hundred seed weight meaning improving seed yield will automatically improve other positively correlated traits. Principal component analysis showed five most important PCs contributing to a total variation of 84.7%. The traits that contributed to the most variation to the total variation observed were plant height, pod length, seed yield, pod bearing and days to flowering. The Shannon weaver indices ranged between 0.98 and 1.00 showing the presence of variation among the qualitative traits measured. The clustering grouped genotypes into three clusters with Tumia and ICEAP 00540 being the most diverse. The diverse genotypes can be used as parents for hybridization and development of transgressive segregants in breeding programmes. There was vast presence of genetic diversity among the pigeon pea genotypes evaluated.

The trail was conducted at Field Experimentation Centre, Department of Genetics and Plant Breeding,NainiAgricultural Institute, SHUATS, Prayagraj during Kharif 2019-2021. The experiment was carried out with17 genotypes (16+1 check variety) of pigeonpea, which were obtained from IIPR, Kanpur (U.P) inRandomized Block Design (RBD) with 3 replications for growth and yield attributes. Observations weremade on five plants that were randomly selected for eleven growth and yield traits except field emergence,days until 50 percent flowering and days to maturity, where the observations were noted on a plot basis.Among the genotypes G13 recorded early days to maturity (252.17), maximum plantâs height (268.70 cm),highest emergence on field (84.67%), more No. of branches/plant (29.67), No. of pods/plant (206.90), No.of seeds/plant (397.93), maximum seed yield/plant (57.00 g.), seed yield/plot (6.45 kg.), 100 seedsweight(15.16 g.) and seed yield q/ha (24.90 q.), while genotype G12 noted less days to 50% flowering (173.83). G-13 and G-7 genotypes taken most down days for flowering and maturity and good yield in comparison tothe check variety (MAL-13). Along with many genotypes G-13 was determined to be the most promisingand should be considered for commercial cultivation under the agro-climatic conditions of Prayagraj.

“…The number of beans per pod ranged from 4.00 (CVPP-20-039), (CVPP-20-059) to 7.00 (CVPP-20-061) with a mean value of 5.40. Ojwang et al (2016) reported the average number of beans per pod ranged from 4.8 (LRG 229) to 7.0 (LRG 267) at crop season and from 4.7 (LRG 052) to 6.0 (LRG 235) at ratoon season in pigeonpea. The bean length ranged from 0.34 (CVPP-20-007) to 0.98 cm (CVPP-20-032) with a mean value of 0.58 cm.…”

A study was conducted to determine the genetic variability among sixty four vegetable pigeonpea genotypes for ten quantitative and quality traits. Highly significant differences existed among the genotypes for all the ten characters studied. Phenotypic coefficients of variation (PCV) were found higher than the genotypic coefficient of variation (GCV) for all the traits. High PCV and GCV was observed for total soluble sugars (28.73, 27.94 %) and hundred fresh bean weight (26.54, 25.87 %), respectively. PCV and GCV values were moderate for the traits viz., fresh pod length, fresh pod width, the number of beans per pod, bean length, bean width, protein content and fibre content. High heritability was observed for fresh pod length, fresh pod width, the number of beans per pod, hundred fresh bean weight and total soluble sugars. High heritability coupled with high genetic advance as per cent of mean was observed for fresh pod length, fresh pod width, hundred fresh bean weight and total soluble sugars indicating the additive gene effect. The genotypes viz., showed a good performance for quantitative and nutritional traits and were superior over the check varieties. The promising genotypes identified for different vegetable traits could be used in the breeding programme to develop vegetable/dual purpose varieties in pigeonpea.
