Assessment of Genetic Variability for Agro-morphological Traits of Vegetable Pea (Pisum sativum var. hortense. L.) under Bundelkhand Region, India

Abstract

This study aimed to assess the genetic variability for agro-morphological traits of vegetable pea (Pisum sativum var. hortense.L) under the Bundelkhand region of India Department of Vegetable Science,College of Horticulture at Banda University of Agriculture & Technology,Banda. A total of 15 pea accessions were collected from different regions of Uttar Pradesh and evaluated for various agro-morphological traits. The data were recorded for Days to first flowers initiation (DFFI), Days to 50% flowering (D50F),Shelling % (S%), Total soluble solids(TSS%),Days to first fruit set (DFFS), Days to maturity(DTM), Pod length (PL), Number of seed per pod(NSP), Plant height(PH), Number of pod per plant (NPP),Number of primary branch per plant (NPBP), Pod weight(PW) and Green pod yield (kg/ha )(GPY). Based on the phenotypic data and Tukey honest test, a few genotypes were identified as superior for different traits. For example, Kasha Sakti showed the highest TSS during both growing seasons, while Kashi Nandani exhibited the highest green pod yield in both years. Pusa Shree was the earliest entry for DFFI in 2019-20, and Kashi Samridhi was the late entry for DFFI in both years. Principle component analysis revealed that the first four principle components contributed to 68% of the total variation, and these four were given due importance for further explanation. Overall, the study indicates that the genetic diversity for agro-morphological traits in pea accessions under Bundelkhand region is high, which can be harnessed for the development of high-yielding varieties.
