EVALUATING INTERACTIVE EFFECT OF INITIAL SCREENING HYBRIDS IN DIFFERENT ENVIRONMENTAL CONDITION
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 20
Abstract
Thirty hybrids were produced after the cross formation from 5 QPM (Quality Protein Maize) and 6 non QPM inbreds in two environments viz. 1) Irrigated Agricultural Farm BHU Varanasi and, 2) Rain-fed RGSC, Barkachha, Mirzapur during Rabi (winter) season 2015-16 and Kharif (rainy) season 2016. These inbreds were selected from the normal irrigated environments. Total thirty hybrids were grown under different irrigated and rain-fed environments in randomized block design, in which rain-fed environment irrigation was controlled. Data were collected after the single and double cross formation in Rabi (Winter) season 2015-16 and Kharif (Rainy) season 2016. From the initial screening observations were recorded on important yield and quality traits of thirty hybrids such as, plant height (cm), days to tasseling, days to silking (days/plot), days to maturity (days/plot), grain yield per plot (GYP). Such types evaluate suitability of hybrids and select for the next generation, on the basis of best performance. There were only five hybrids selected from the both environment which better survived at high temperature. The selected hybrids could be grown in normal (Irrigated), poor environment (rain-fed) and new environment (Rabi), which will bring high level of food and nutritional security in India.
