Abstract
Abstract According to the invention, there is provided an inbred corn line, designated PHHB4. This invention thus relates to the plants and seeds of inbred corn line PHHB4 and to methods for producing a corn plant produced by crossing the inbred line PHHB4 with itself or with another corn plant. This invention further relates to hybrid corn seeds and plants produced by crossing the inbred line PHHB4 with another corn line or plant.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
11 words
Inbred corn seed designated PHHB4 and having ATCC Accession No. 97048.
Claim 2
Dependent Claim
11 words
Inbred corn seed designated PHHB4 and having ATCC Accession No. 97048.
Claim 3
Dependent Claim
10 words
A corn plant produced by the seed of claim 1.
Claim 4
Dependent Claim
24 words
A tissue culture of regenerable cells of a corn plant wherein the tissue regenerates plants having all the physiolofiical and morphological characteristics of PHHB4.
Claim 5
Dependent Claim
24 words
A tissue culture of regenerable cells of a corn plant wherein the tissue regenerates plants having all the physiolofiical and morphological characteristics of PHHB4.
Claim 6
Dependent Claim
34 words
Tissue culture according to claim 3, the tissue culture selected from the group consisting of leaves, pollen, embryos, roots, root tips, anthers, silk, flowers, kernels, ears, cobs, husks, stalks, and cells and protoplants thereof.
Claim 7
Dependent Claim
32 words
A corn plant regenerated from a tissue culture of claim 3 wherein the regenerated plant has a genotype capable of expressing all the physiological and morphological characteristics of inbred corn plant PHHB4.
Claim 8
Dependent Claim
124 words
A process to produce a hybrid corn seed which gives rise to a hybrid corn plant having alleles which, when expressed, contributes to high yield, brittle stalk resistance, and common rust resistance in wet and dry years, when compared to similarly adapted hybrids, comprising the steps of: (a) planting, in pollinating proximity, seed of corn inbred line PHHB4 and another inbred line, not PHHB4; (b) cultivating corn plants resulting from said planting, said corn plants having a male and female reproductive system; (c) inactivating the male reproductive system prior to pollination of the plants of either the female inbred line; (d) allowing natural cross pollinating to occur between the inbred lines; and (e) harvesting seeds produced on said inactivated plants of the inbred line.
Claim 9
Dependent Claim
124 words
A process to produce a hybrid corn seed which gives rise to a hybrid corn plant having alleles which, when expressed, contributes to high yield, brittle stalk resistance, and common rust resistance in wet and dry years, when compared to similarly adapted hybrids, comprising the steps of: (a) planting, in pollinating proximity, seed of corn inbred line PHHB4 and another inbred line, not PHHB4; (b) cultivating corn plants resulting from said planting, said corn plants having a male and female reproductive system; (c) inactivating the male reproductive system prior to pollination of the plants of either the female inbred line; (d) allowing natural cross pollinating to occur between the inbred lines; and (e) harvesting seeds produced on said inactivated plants of the inbred line.
Claim 10
Dependent Claim
77 words
Hybrid seed produced by: (a) planting, in pollinating proximity, seeds of corn inbred lines PHHB4 and another inbred line, not PHHB4; (b) cultivating corn plants resulting from said planting, said corn plants having a male and female reproductive system; (c) inactivating the male reproductive system prior to pollination of the female inbred line; (d) allowing natural cross pollinating to occur between said inbred lines; and (e) harvesting seeds produced on said inactivated plants of the inbred line.
Claim 11
Dependent Claim
77 words
Hybrid seed produced by: (a) planting, in pollinating proximity, seeds of corn inbred lines PHHB4 and another inbred line, not PHHB4; (b) cultivating corn plants resulting from said planting, said corn plants having a male and female reproductive system; (c) inactivating the male reproductive system prior to pollination of the female inbred line; (d) allowing natural cross pollinating to occur between said inbred lines; and (e) harvesting seeds produced on said inactivated plants of the inbred line.
Claim 12
Dependent Claim
8 words
