inbred corn line php60 is a yellow , dent corn inbred with superior characteristics and provides an acceptable female parental line in crosses for producing first generation f 1 corn hybrids . this inbred is best adapted over the southeastern areas of the united states . the inbreds can be used to produce hybrids from approximately 122 - 136 relative maturity based on the minnesota relative maturity rating system for harvest moisture of grain . php60 is best used as the female parent because of its acceptable female yields , but it is not acceptable as a male parent because of poor pollen shed . in the pollen yield test , php60 averaged only 51 percent ( 51 %) of the experimental mean for amount of pollen in the pollen yield test averaged over 9 locations . the inbred has shown uniformity and stability within the limits of environmental influence for all the traits as described in the variety description information ( table 1 ) that follows . most of the data in the variety description information was collected at johnston , iowa . this inbred has been self - pollinated and ear - rowed a sufficient number of generations with careful attention paid to uniformity of plant type to ensure homozygosity and phenotypic stability . the line has been increased both by hand and in isolated fields with continued observations for uniformity . no variant traits have been observed or are expected in php60 . inbred corn line php60 , being substantially homozygous , can be reproduced by planting seeds of the line , growing the resulting corn plants under self - pollinating or sibpollinating conditions with adequate isolation , and harvesting the resulting seed , using techniques familiar to the agricultural arts . table 1______________________________________php60variety

4______________________________________ this invention also is directed to methods for producing a corn plant by crossing a first parent corn plant with a second parent corn plant wherein the first or second parent corn plant is an inbred corn plant from the line php60 . further , both first and second parent corn plants can come from the inbred corn line php60 . thus , any such methods using the inbred corn line php60 are part of this invention : selfing , backcrosses , hybrid production , crosses to populations , and the like . all plants produced using inbred corn line php60 as a parent are within the scope of this invention . advantageously , the inbred corn line is used in crosses with other , different , corn inbreds to produce first generation ( f 1 ) corn hybrid seeds and plants with superior characteristics . as used herein , the terms &# 34 ; plant and plant parts &# 34 ; include plant cells , plant protoplasts , plant cell tissue culture from which corn plants can be regenerated , plant calli , plant clumps , and plant cells that are intact in plants or parts of plants , such as embryos , pollen , flowers , kernels , ears , cobs , leaves , husks , stalks , roots , root tips , anthers , silk and the like . tissue culture of corn is described in european patent application , publication 160 , 390 , incorporated herein by reference . corn tissue culture procedures are also described in green and rhodes , &# 34 ; plant regeneration in tissue culture of maize ,&# 34 ; maize for biological research ( plant molecular biology association , charlottsville , va . 1982 , at 367 - 372 . thus , another aspect of this invention is to provide cells which upon growth and differentiation produce the inbred line php60 . the utility of inbred line php60 also extends to crosses with other species . commonly , suitable species will be of the family graminaceae , and especially of the genera zea , tripsacum , coix , schlerachne , polytoca , chionachne , and trilobachne , of the tribe maydeae . of these , zea and tripsacum , are most preferred . potentially suitable for crosses with php60 may be the various varieties of grain sorghum , sorghum bicolor ( l .) moench . corn is used as human food , livestock feed , and as raw material in industry . the food uses of corn , in addition to human consumption of corn kernels , include both products of dry - and wet - milling industries and alkaline cooking . the principal products of corn dry milling are grits , meal and flour . the corn wet - milling industry can provide corn starch , corn syrups , and dextrose for food use . alkaline cooking provides snack foods ( i . e ., corn chips , tortillas , etc .) corn oil is recovered from corn germ , which is a by - product of both dry - and wet - milling industries . corn , including both grain and non - grain portions of the plant , is also used extensively as livestock feed , primarily for beef cattle , dairy cattle , hogs , and poultry . industrial uses of corn are mainly from corn starch from the wet - milling industry and corn flour from the dry - milling industry . the industrial applications of corn starch and flour are based on functional properties , such as viscosity , film formation , adhesive properties , and ability to suspend particles . the corn starch and flour have application in the paper and textile industries . other industrial uses include applications in adhesives , building materials , foundry binders , laundry starches , explosives , oil - well muds , and other mining applications . plant parts other than the grain of corn are also used in industry . stalks and husks are made into paper and wallboard and cobs are used for fuel and to make charcoal . the seed of inbred corn line php60 , the plant produced from the inbred seed , the hybrid corn plant produced from the crossing of the inbred , hybrid seed , and various parts of the hybrid corn plant can be utilized for human food , livestock feed , and as a raw material in industry in the examples that follow the traits and characteristics of inbred corn line php60 are given as a line and in hybrid combination . the data collected on inbred corn line php60 is presented for the key characteristics and traits . the results in table 3 compare php60 to b73 . b73 is an important inbred developed by iowa state university and is used in the area that php60 would be used and would cross well with some of the same inbred lines . the results show that the two inbreds differ significantly for a number of traits . php60 is later maturing ( flowering and harvest moisture of grain ), has higher percentage of large kernels , is shorter and lower eared , has harder textured grain , higher stay green scores , and better stalk lodging resistance than b73 . php60 has better ear mold tolerance , gray leaf spot tolerance , and much better southern leaf blight tolerance which makes it an important new female to use in the south . the results in table 4 compare php60 to phv78 . phv78 ( pvp certificate # 8800003 , u . s . pat . no . 4 , 812 , 599 ) is an important inbred that would be used in the area that php60 would be used and would cross well with some of the same inbred lines . this data was collected over four years of research testing . the results show that the two inbreds differ significantly for a number of traits . php60 had a five - bushel per acre yield advantage over phv78 , had higher grain test weight with better grain quality and harder textured grain , and better stay green than phv78 . php60 was also more resistant to southern leaf blight , gray leaf spot , fusarium and general ear molds than phv78 . the results in table 5a compare a php60 hybrid to a b73 hybrid from one research station in the south central corn belt . although the data is limited it shows some significant differences between the b73 and php60 hybrids . the php60 hybrid was later maturing ( flowering and grain harvest moisture ) and had better stay green . the results in table 5b compare php60 to phv78 crossed to the same inbred testers . this data was collected in the central and southern corn belt . the results show that the two lines also differ significantly for a number of traits in hybrid combination . the php60 hybrids had better resistance to root lodging , better stay green and better grain test weight than the phv78 hybrids . php60 has given good performance in specific hybrid combinations for the southeast . the results in table 6 compare a php60 hybrid to pioneer ® brand hybrid 3343 where both hybrids have a parent in common ( not php60 ). this data has been collected over one year of research testing in the central and southern corn belt . the data in the comparison is from shelbyville , illinois and union city , tennessee . the comparison shows that the php60 hybrid has much higher test weight grain than 3343 . the results in table 7 compare the performance of a php60 hybrid to pioneer ® brand 3295 where the hybrids have a parent in common ( not php60 ). the hybrid 3295 is grown in some of the areas where the php60 hybrid is grown but will not be utilized as far south . the php60 hybrid is later for harvest moisture maturity , has higher yields , better stay green , improved test weight , better grain quality and is a taller hybrid than 3295 . the results in table 8 compare the performance of a php60 hybrid to pioneer ® brand 3140 . although the two hybrids have no parents in common , 3140 is a fairly new very important hybrid that is used in the same area as the php60 hybrid . the php60 hybrid has higher yield , lower harvest moisture of the grain , with better test weight and grain quality , and improved stand establishment in the spring compared to 3140 . these characteristics will make the php60 hybrid very important in the southeast . table 3__________________________________________________________________________paired inbred comparison
