SYNOPSIS PRESENTATION OF RESEARCH WORK ENIITLE “ Genotypic responses of pearl millet ( Pennisetum glaucum L. ) to high temperature stress” Name of Student : DAPKE JITENDRA SUBHASH Registration No . : 04-00656-2010 Major Subject : Plant Breeding and Genetics Major Advisor : Dr. D. S. Shah Associate Research Scientist, Center for Crop improvement S.D.A.U .

PowerPoint Presentation: 

Introduction Pearl millet [ Pennisetum glaucum L. ] belong to gramineae family Chromosome number 2n= 14 Originated in Africa and was subsequently introduced into India. It is one of the most important food grain cereal crop of India and rank 4 th in area The total area under pearl millet cultivation in India was 9.50 million hectares with production of 9.79 million tones having productivity of 1030 kg/ha during 2008-2009

PowerPoint Presentation: 

In Gujarat, area having 5.28 lakh hactares under bajra crop with an annual production of 5.35 lakh tonnes and productivity of 1012 kg/ha during 2008-2009. Bajra is low price food grain crop. Mainly consumed by middle and poor class families The nutritive values of the pearl millet grains are fairly high with 69.4% carbohydrate, 12.1% protein, 4.3 to 5.0 % fat and 2.4% sugar. It is also produces large amount of good quality dry fodder

PowerPoint Presentation: 

OBJECTIVES OF THE EXPERIMENT To study genetic variability, heritability and genetic advance for different quantitative characters in different temperature. To estimate the direct and indirect effects of grain yield components by partitioning the total component through path coefficient analysis. To study the association between grain yield and its component estimating genotypic and phenotypic correlation coefficients. To derive the stability parameters of various genotype under different environmental (temperature) condition.

CHRACTERS TO BE STUDIED

PowerPoint Presentation: 

Observation will be recorded on Five competitive plants which are randomly selected from each plot of three replication and selected plants will be tagged observation will be recorded on single plant basis Inter and intra row spacing would be 45 cm and 15 cm respectively with row length of 3 m long

PowerPoint Presentation: 

Days to 50 percent ear head emergence The number of days from the date of Sowing to the flower ear head appeared in 50 Percent plants will be counted . Days to maturity The total number of days required for physiological maturity from date of sowing will be considered . Plant height (cm) Plant height will be measured from the ground level to the panicle in centimeters at harvesting Stem girth (cm) Stem girth will be measured by using centimeter scale on five observation plants and averages will be calculated Number of leaves per plant Total number of intact leaves will be counted.

PowerPoint Presentation: 

Leaf length (cm) The length of leaf will be measured in centimeters from base of the leaf to the tip of fully grown leaf at flowering stage. Total Number of tillers per plant Total number of tillers would be counted at the time of maturity. Number of effective tillers per plant Total number of ear bearing tillers would be counted at the time of maturity. Area of flag leaf (cm) Flag leaf area measured following formula Minimum length of leaf  maximum breath of leaf  0.474. Ear head length (cm) It will be measured in centimeters from the base of panicle to the tip of panicle at the time of harvesting.

PowerPoint Presentation: 

Ear head diameter (cm) It will be measured in centimeters. Ear head weight Total number of panicle will be weighted. Grains weight per ear head (g) A Random sample of 10 sun dried ear head harvest from individual plant will be recorded on average basis in grams. Grain yield per plant (g) Total grains from individual plant will be weighed in grams. Fodder yield per plant Total fodder from individual plant will be weighed in grams. Iron and Zink content in seed By Atomic absorption spectrophotometry Harvest Index
